— A —
To terminate a transaction in such a way that the values assigned to all protected resources, such as database records, are unchanged from the beginning of the transaction.
Set of restrictions on the ability of principals (human or software entities) to use software resources. These restrictions are enforced in order to prevent unauthorized use of such resources.
access control information (ACI)
Information about the initiator of a resource access request. The ACI is used to make a decision about enforcing access control.
Data structure used to authorize or prohibit the use of resources, such as network services, by principals. Each entry in an ACL contains a set of permissions associated with a particular principal.
The WebLogic Server implementation of ACLs is based on the java.security.acl package.
In a WebLogic Integration environment, the use of different types of resources is granted to different types of principals:
See also authentication, realm, permission, and principal.
Essential characteristics of transaction processing systems:
See access control list (ACL).
Basic unit of work performed during business process management functions (which are supported by WebLogic Integration). Actions define workflow and task behavior, and can be defined as parts of tasks, decisions, and events. WebLogic Integration provides numerous actions.

See also Component Object Model (COM).
Promotional message presented in any of various formats: a piece of HTML text, an image (GIF, JPG, PNG), or a Shockwave movie.
Ads work with ad placeholders, mechanisms that query the content management system for ads and display the results in a JSP. A Business Analyst uses the BEA E-Business Control Center to define queries for an ad placeholder and a Business Engineer (BE) creates a placeholder tag in the location in which the Business Analyst wants to display ads. A Business Analyst can also create a campaign scenario that places additional queries in an ad placeholder.
See also E-Business Control CenterTM, Business Analyst (BA), and Business Engineer (BE).

See also WebLogic Integration B2B Console and WebLogic Server Administration Console.
Advanced Program to Program Communications (APPC)
Software protocol that makes possible high-speed communications, over SNA, among programs on different computers, including portables, workstations, and midrange and host computers. This protocol is open and published. Also known as LU 6.2.
See also Systems Network Architecture (SNA).
Feature of the Personalization Server that ties together the services and components in the Personalization Server to deliver personalized content to a Web site visitor. It does this by matching content to information contained in the user profile. Specifically, it gathers information from the user profile with the User Management component, submits that information to the Rules service, and queries the document management system that the Content Management component uses. Developers determine whether the Advisor displays the results of the query with a JSP or a Java servlet.
The Advisor includes a JSP tag library and an API that EJB developers can use to access the underlying EJB stateless session bean.
See also developer, Enterprise JavaBeans (EJB), application programming interface (API), user profile, and Web application (Webapp).
Type of principal that accesses a resource in a WebLogic Server environment without being authenticated.

J2EE Connector Architecture standards-based integration broker developed by BEA Systems, Inc., as part of WebLogic Integration, for interenterprise and intraenterprise integration.
application programming interface (API)
See also enterprise resource planning (ERP).
Business-level interface to the functionality in an application. An application view is configured for a single business purpose, and contains only services related to that business purpose. Additionally, an application view represents both events and services that support a business purpose, allowing the business user to interact with the application view for all communication with an application.
Characteristic of events that occur at different times such that the relationship between the times when those events occur is unpredictable.
In distributed application architectures such as Web services, clients invoke methods (or send messages to) servers and servers respond. If a client is blocked from performing other work while waiting for a server to respond, the interaction is described as synchronous because the client is synchronized with the server.
If an interaction is designed such that a client can continue performing other work while the server prepares its response, and the server can notify the client when the response is ready, the interaction is described as asynchronous.
An asynchronous architecture is useful in event-driven scenarios, in which an event can arrive at any time and the receiver can handle it whenever it arrives.
Information that is sent with a business message.
See also access control list (ACL) and secure sockets layer (SSL).
Process of determining which services may be accessed by a particular entity (a user or a process) and then giving permission to that entity to access those services.
In a WebLogic Integration environment, trading partner authorization is a role-based security feature whereby a trading partner is allowed to send and receive certain types of messages, as defined by the trading partner's subscription in a specific conversation. Trading partners are authorized to access the transport servlet and the JDBC pool.
In addition, the WebLogic Integration software is authorized to access the transport servlet in order to send messages to trading partners.
Human users can be authorized to access JSPs and, indirectly, the JDBC pool. A WebLogic Server access control list (ACL) can be configured selectively to allow or deny a user access to a resource.
— B —

— C —
Compressed file used to load classes and other files required to run an applet in a single hypertext transfer protocol (HTTP) request. Can be used only with applets running under Microsoft Internet Explorer, version 4.0 or later.
See also JAR file, applet, and hypertext transfer protocol (HTTP).
Method defined on the client that can be called by your service. Callbacks make it possible to support an asynchronous two-way exchange between a client and a service. For example, if a service performs a time-consuming operation, the service can immediately acknowledge the client's request with a simple return value, then later use the callback to return the full result of the operation. A callback must participate in a conversation.
Method run by your service when it receives a corresponding callback. It is defined by the control that includes the callback. For example, the timer control provides the onTimeout method as a callback handler. You have the option of adding code that will run when the timer fires.
Principal that is associated with an application component instance during a method invocation. For example, an EJB instance can call the getCallerPrincipal method to get the principal associated with the current security context.
See also Enterprise JavaBeans (EJB) and principal.

You can specify a campaign sponsor by using the BEA E-Business Control Center.
See also E-Business Control CenterTM.
State of a campaign: active or deactive.
When a campaign is saved, it is in an active state. In other words, the campaign is ready to run between the specified start and stop times, and when the appropriate conditions are met.
When you disqualify an active campaign from running, or when you stop a running campaign before it reaches either the specified stop date or its goals, the
campaign is in a deactive state. In the campaign list of the E-Business Control Center (shown in the Control Center's Explorer window) deactivated campaigns are displayed in a lighter color than other items in the list.
See also E-Business Control CenterTM.

See also certificate authority (CA) and certificate authentication (CA).
certificate authentication (CA)
Method of providing a confident identification of a client by a server through the use of digital certificates. Certificate authentication is generally preferred over password authentication because it is based on what the user has (a private key), as well as what the user knows (a password that protects the private key).
See also authentication, certificate authority (CA), and certificate.
Standard interface defined in WebLogic Server to map digital certificates to WebLogic Server users. After verifying an incoming certificate, the certificate authenticator maps the incoming trading partner associated with the certificate to the corresponding WebLogic Server user, based on the certificate.

See also certificate and certificate authentication (CA).
Well-known and trusted organization, such as VeriSign, that issues digital certificates for the purpose of authenticating a certificate holder's identity to another party.
Process that causes a Webflow to move from one processor node (that is, an input processor or pipeline) to another processor node. This mechanism relieves you of the need to use processor nodes between presentation nodes. In a chaining
arrangement, the result state of one successfully executed processor node is another processor node.
See also input processor, node, pipeline, and Webflow.
Interactive process whereby a customer confirms items to be purchased, and provides payment and shipping information. The Commerce services then validate the customer information, post the credit card transaction, and log shipping and tax payment requirements.

List of paths for the file system directories or Java archive files to be searched by a Java Virtual Machine (JVM) at run time, in order to locate the executable class files required at that time. The list may be supplied through an operating system environment variable (CLASSPATH) or a command-line switch (-classpath) sent to the virtual machine. Application server containers, such as servlet engines and EJB containers, may contain additional levels of classpath information.
See also class and class library.
Act of clicking an ad. The number of clickthroughs can be used as one criterion to determine whether the goal of a campaign has been met.
If a client is located on a machine that belongs to the domain to which the target servers also belong, then the client is called a native client. If the client is located on a machine outside that domain, then the client is called a remote client or a Workstation client.
Entity that makes a request to a Web service to return data. Can be written in any language and run on any platform, as long as it communicates in the manner expected by the Web service. Most Web services expect to receive requests over an Internet protocol, such as HTTP, and they expect those requests to be XML messages formatted according to the SOAP specification.
client connector interface (CCI)
Interface that allows a J2EE-based application to connect to back-end systems and access them. The CCI manages the flow of data between a client application and its back-end system. It does not have any visibility into the activities, with the adapter, of the container or the application server.
Network in which heterogeneous clients make requests over various protocols for many different services on the network and the requests are fulfilled transparently by a high-performance, intelligent intermediate server or cluster of servers, such as the pure-Java WebLogic Server.
See also client/server and Web service.
Network architecture in which computer processing is distributed among clients (desktop PCs) and a server or servers (central computer).
Group of servers that work together to provide an application platform that is more powerful and reliable than a single server. A cluster appears to its clients as a single server but it is, in fact, a group of servers acting as one. If properly designed and configured, a cluster can provide both availability and scalability. New processes and machines can be added to a cluster, dynamically, to handle increased load without shutting down the cluster. Individual servers can be removed from the cluster periodically so that maintenance can be done without affecting cluster performance.
Clusterable stub is a wrapper that delegates its calls to a service instance. It has intelligence about how to deal with load balancing and failover situations, in which a service might be handled transparently by another server. You generate clusterable stubs by setting the -clusterable flags for RMIC or similar EJB deployment descriptor properties.
See also failover, load balancing, and stub.

Confirmed_Delivery_to_Destination
Quality of Service (QoS) option that verifies receipt of a message by all recipient trading partners. Delivery can be made more reliable by use of options such as Retry Attempts and Durability (Persistent option).
Confirmed_Delivery_to_Destination can also provide additional information to the sender and administrators, including delivery status from recipients, complete message tracking for administrators, and confirmation from the B2B integration component of WebLogic Integration upon completion of delivery. Availability depends on the business protocol that is used.
Default Quality of Service (QoS) option that verifies receipt of a message by the B2B integration component of WebLogic Integration. This option is often used when system performance is an issue. It does not provide delivery status from recipients, nor does it provide message tracking. Because the selection process for trading partners is performed after confirmation reaches the sender, no information about potential recipients is available. Availability depends on the business protocol that is used.
Provides connectivity to a resource manager and enables an application client to connect to a resource manager, perform transactions, and access services provided by that resource manager. A connection can be either transactional or nontransactional. Examples include a database connection and an SAP R/3 connection.
In Webflow, a small graphical device on the edge of a node that marks the point at which an event or exception is connected to that node. In some cases, it may be helpful to move the node's connection port.
See also node and Webflow.
In a WebLogic Server environment—Pseudomethod used to create an object. In Java, constructors are instance methods with the same names as their classes. Java constructors are invoked using the new keyword.
See also class, instance, Java, metadata interface, and object.
Part of an application server, such as WebLogic Server, that provides deployment and run-time support for application components. A container allows you to monitor and manage supported components as well as the service(s) that monitor and manage the components. A container can be any of the following:
See also Enterprise JavaBeans (EJB), Java Server Pages (JSP), and servlet.
Transaction in which an Enterprise JavaBean container controls the transaction boundaries. In a container-managed transaction, controls are specified in the deployment descriptor. When a bean method is invoked, the container manages the transaction, which begins and ends in the same method. An entity bean must use container-managed transactions.
See also bean-managed transaction and transaction.
System that manages a collection of content objects (articles, documents, images, and so forth), including metadata about the content. Content management systems, such those marketed by Interwoven and Documentum, usually provide services such as retrieval of content and content authoring services. Content authoring services may include services for creating, editing, and versioning content objects, and workflow services
Key WebLogic Personalization Server component that provides access to content via both JSP tags and EJBs. The JSP tags provide a developer with an enumeration of content objects by querying the content database directly using a search expression syntax. The content management tools are designed to be used with the rules manager and rules services, user profiles, and property set manager to create personalized content delivery on an e-commerce site. The primary interface to the functionality of the content management component is the ContentManager session bean.
See also Enterprise JavaBeans (EJB), JSP tag, property set management, and user profile.
Mechanism that queries, under a set of conditions, the content management system for documents. In the BEA E-Business Control Center, a Business Analyst specifies the conditions that trigger a content selector to run a query. A Business Analyst also uses the BEA E-Business Control Center to construct the query that the content selector runs. A Business Engineer creates a content-selector JSP tag where the Business Analyst wants to display documents.
See also E-Business Control CenterTM, Business Analyst (BA), and Business Engineer (BE).
Component used in a Web service so that a service can communicate with other kinds of applications and components. For example, a database control enables a Web service to request data from a database. A service control makes it easy for one Web service to call another.
Service that manages conversation life cycles, according to the rules of the corresponding business protocols, and supports long-living, durable conversations that span multiple organizational boundaries. The conversation coordinator generates conversation IDs; registers trading partners in a conversation; delivers business and system messages to clients; maintains status information about conversations; and provides the conversational context for execution of the business protocol.
Collection of values that specifies the parameters of a conversation.
Trading partner that initiates and terminates a conversation.
Period during which messages are exchanged between trading partners.
Trading partner that receives and processes business messages.
Intelligent and controlled cessation of message exchanges performed as part of a B2B integration or business process management (BPM) function, both of which are supported by WebLogic Integration:
Interface that enables a trading partner to send and receive business messages in conversations. A conversation handler must be registered for one or more conversation types in order for the associated trading partner to participate in conversations.
MBean interface that represents a conversation. WebLogic Integration management applications use ConversationMBean objects to monitor conversations in a run-time environment.
Common piece of source code designed to be copied into many source programs; used mainly in IBM DOS mainframe programming. In mainframe DOS (for example, DOS/VS and DOS/VSE), the copybook was stored as a book in a source library. A library comprising books, the name of each of which began with a letter prefix designating a programming language (for example, A.name for Assembler, C.name for COBOL) because DOS did not support multiple or private libraries. This term is used mainly by COBOL programmers, but it is supported by most mainframe languages. The IBM OS series did not use the term copybook; instead, it referred to such files as libraries implemented as partitioned data sets or PDSs. A copybook is functionally equivalent to a C or C++ include file.
See common object request broker architecture (CORBA).
Capability provided automatically, by WebLogic Workshop, to Web services. If a Web service has many simultaneous clients, it must keep track of which responses go to which clients in response to requests. This includes callbacks: when events occur in the Web service that must be passed on to clients via callbacks, WebLogic Workshop's correlation capability routes the callback messages automatically.
Quality of Service (QoS) option that contains the message identification string. It can be used to correlate different business messages within an application. Availability depends on the business protocol that is used.
Data entity that contains or references security information that can authenticate a principal to additional services. A principal acquires a credential upon authentication or from another principal that allows its credential to be used: the latter is termed principal delegation. A credential may be a password, an X509 digital certificate or a certificate chain, or any other token that validates a user.
See also realm and user.
Service that defines an interface for giving persistence to custom attributes of product items. (Custom attributes are attributes not defined in the ProductItem interface.)

Standard for assigning nine-digit strings, as internationally-recognized identifiers, to companies that engage in global electronic commerce transactions. Business identifiers are assigned to trading partners for external use by some business protocols; they differ from internal WebLogic Integration trading partner names. Implementations of the RosettaNet business protocol must use DUNS numbers.
Collection of interrelated or independent data items stored together without redundancy to serve one or more applications.
database management system (DBMS)
Program or set of programs that enables users to structure and manipulate the data in the tables of a database. Use of a DMBS ensures data privacy and integrity, and the ability to recover data in a multiuser environment.
Programming classification indicating the type of data in a variable. Some commonly used datatypes are various forms of integers, character, and Boolean. Most programming languages require that the datatype must be declared for data objects or fields. Datatypes are dependent upon the programming language used.
In a WebLogic Server environment—Set of high-level Java objects that may be used with any JDBC driver for database access.
See database management system (DBMS).
The business process management (BPM) term for a workflow component that contains a condition to be evaluated when a transition occurs. The result of the evaluation (true or false) determines the appropriate dependent node to which flow control then passes.
Component that processes the protocol-specific message headers, identifies the sending trading partner, enlists the sending trading partner in a conversation, prepares a reply for the sender, and forwards the message to the scheduling service.

deferred synchronous message delivery
Message delivery method whereby control is returned to the application once a message is sent. A message token is returned to the application, which the application can access later to check the status of message delivery. After the token is accessed, the application waits for a specified time or until one of the following events occur: acknowledgments are received from all potential destinations; the message times out; or the conversation in which the message was sent terminates.
Authorization, by principal A, for principal B to use principal A's identity or privilege, sometimes with restrictions.
Sequence of bytes that denotes the end of a field or group of data.
Specification for delivering business messages to one trading partner. Each trading partner has a delivery channel for each business protocol supported by the trading partner.

See also E-Business Control CenterTM and scenario action.
A business process management (BPM) term for a workflow. To execute an event node, the workflow waits for an XML message to trigger the event. When that trigger occurs, various sub-actions defined within the event node can be executed or workflow variables can be set.
One-way asynchronous notification of an event within a system (generally an EIS). An event notification is achieved by delivering an event object representing the event to a subscriber for that type of event.
Data object that represents an event within a system (generally an EIS). Event objects generally contain data sufficient to describe the event and the context in which it occurred. Event objects are often referred to simply as events. This is because event objects are the only representation of an event possible after the event has passed, and therefore are the lasting outcome of an event. An event object has a type that is a name used to refer to all events with the same cause. An event object contains an XML document that contains the data for the event.

XML facilitates the development of user-defined document types and the creation of programs that can use data from documents of such types. It is rapidly becoming a universal standard for defining, validating, and sharing data formats and documents.
Because XML is text-based (that is, it is not written in binary format), and it uses syntax rather than binary markers to organize data, it can be deployed across heterogeneous and potentially incompatible systems and platforms.
XML is a crucial component of the WebLogic Integration solution.
eXtensible Stylesheet Language (XSL)

See integrated development environment (IDE).
A function, f, is considered idempotent if f(f(x)) = x. Computer science defines a procedure as idempotent if it produces the same result every time it is performed with the same arguments.
This property is especially useful when dealing with a retry of a replicated object. When a communication failure occurs during an attempt to invoke a remote method, it is not always possible to know whether the failure occurred before or after the method invoked was completed on the server. If the failure occurred after the method completed on the server, a retry results in the same method being called twice (even if it is called on two servers).
Such behavior can produce incorrect results unless the method being invoked is idempotent. If a method is idempotent, then the process of invoking it multiple times with the same arguments is equivalent to invoking it only once.

— M —
Java object (JavaBean) that, as part of the Instrumentation level in the JMX architecture, contains attributes for management operations. In WebLogic Integration, MBean classes are used to monitor run-time information. MBeans are registered with the MBean server that runs inside WebLogic Integration. When MBeans are created, their attributes are populated from the repository. At run time WebLogic Integration updates MBean attributes to reflect the state of the running system. MBeans are implemented as Standard MBeans; that is, each class implements its own MBean interface.
See also CollaboratorMBean, ConversationMBean, and GlobalConversationMBean.

See also business message, log message, system log message, and trigger item.
Description of a collection of text messages indexed by a unique identifier.
Information that enables recipients of a message to determine the structure and content of the message, as well as the conversation in which the message was sent. Specifically, the message context identifies the following: the relevant conversation, the message definition, the message parts, a content-type for each message part, and a document definition for each message part.
Specification of the business content, or payload of a business message. A message definition consists of ordered message parts, the contents of which may be binary or XML. An XML message part defines a business document and requires a document definition. A binary message part defines an attachment and requires no other information. See business documents and attachments for more information about payloads.
See deferred synchronous message delivery and synchronous message delivery.
Representation of text in the form of a single string of digits, created with a formula called a one-way hash function. Encrypting a message digest with a private key creates a digital signature, which is an electronic means of authentication.
Method of reducing a message of any length to a string of a fixed length, called the message digest or hash value. Message digest algorithms have the property that it is computationally infeasible to find a message that corresponds to a given message digest, or to find two different messages that produce the same message digest. Examples of message digest algorithms are MD5 and SHA-1.
Container for a business message as it travels through the B2B integration feature of WebLogic Integration. As the business message enters, B2B integration creates a message envelope for each intended recipient. In addition to the business message, the message envelope contains high-level routing and processing information, such as URLs for the sender and the recipient.
Description of a binary format produced by Format Builder.

Token that is returned to an application after the application sends a message. The token provides the following information: the message ID; the ID of the conversation in which the message was sent; whether the message was sent successfully; the amount of time that elapsed before all recipients sent acknowledgments, whether the Quality of Service (QoS) delivery option allows this information to be sent; the number of recipient destinations after the initial selection (RPC specifications applied); and the number of recipient destinations after the final selection.
Feature that provides information about the status of a message as the message progresses through various predefined message-tracking locations in the B2B integration messaging system. WebLogic Integration administrators can use message-tracking information for debugging and identifying bottlenecks in the system. The availability of message-tracking locations depends on the configuration of the WebLogic Integration system, the Quality of Service (QoS) for the message, and the business protocol.

Database schemas and XML DTDs are examples of metadata.
See also content management system.
Interface that accesses information about data; descriptive information about a particular object.
In object-oriented programming, a programmed procedure that is defined as part of a class and included in any object of that class. A class (and thus an object) can have more than one method. A method in an object can have access only to the data known to that object, which ensures data integrity among the set of objects in an application. A method can be reused in multiple objects.

See also WebLogic Server jDriver.
Icon that represents a state in a Webflow mechanism. Depending on the node type (presentation or processor), there are a number of predefined events that may occur (such as a visitor clicking a link on a Web page). When a particular event happens, the Webflow decides which subsequent node to invoke to continue the flow. The invocation of a node to continue the flow is referred to as a transition.
See also presentation node, processor node, and Webflow.
Defines an operational environment for a two-tier application. An application client directly uses a resource adapter to access the enterprise information system (EIS); the EIS defines the second tier for a two-tier application.
Default Durability Quality of Service (QoS) option whereby a message is not stored anywhere in the WebLogic Integration system. A message sent with this option is not recoverable in the event of a whole or partial system failure that occurs while the message is enroute to its destination. Messages delivered with this option use fewer system resources and thus provide better throughput.
Mechanism that provides legal proof that a message was sent or received. Nonrepudiation of origin provides legal proof that a message was sent; it links a received message to the sender of the message. Nonrepudiation of receipt provides legal proof that a message was received; it links a processed message to the recipient of the message.

Ability to carry out certain operations on certain objects, as defined in an access control list. Permissions may be positive (explicitly allowing certain operations on certain objects), or negative (explicitly disallowing certain operations on certain objects). In a WebLogic Server environment, all permissions are positive; to disallow an operation, you must exclude a principal from the ACL that authorizes the operation.
See also realm, access control list (ACL) and principal.
Process that saves information or state, in a resource such as a file or database, that would otherwise be transient.
Durability Quality of Service (QoS) option whereby a message is stored at, and forwarded from multiple locations between its source and destination, during the course of its delivery, as a safeguard in case of machine failures. This process is called persisting a message. An application can direct the system to persist messages on a per-message or per-conversation basis. However, the B2B integration component of WebLogic Integration must be recoverable in order for the message to persist. Persistence is achieved at the expense of system throughput. A persistent message travels more slowly and consumes more resources than a message that is namespace.

See also application programming interface (API).
Service that creates, gets, updates, and deletes items within the Commerce services product catalog.
Mechanism for storing metadata using name/value pairs. All properties include the following information: property name, data type and selection mode—which specifies whether a property is single-valued (that is, it has a single default value) or multilevel (that is, it has a collection of default values)—and value ranges for defining default values.
Collection of metadata that describes a logical grouping of properties. Property sets allow properties to be conveniently grouped, and allow multiple properties with the same name to be defined.
WebLogic Portal component that you can use to name properties and group them into property sets, which you can also name. Properties represent the attributes of an object. For example, backgroundColor is a property of an HTML page.
When you create a property, you specify the type of attribute value (for example, text, integer, date/time), whether it defines multiple or single values, whether it restricts values to a certain set, and a default value. You can create property sets based on the following types: User/Group, Session, and Request.
You can apply named properties and property sets to users and groups, HTTP sessions and HTTP requests (wrapped by a ConfigurableEntity component), or content that is accessible from the Content Manager. However, property sets do not manage content; the document loader utility, or a third-party content management tool, manages content metadata.
For example, developers want visitors to be able to specify different background colors for each of their portals. By creating portal A and portal B property sets, the property backgroundColor can exist for both portal A and portal B. While the two backgroundColor properties have the same name, they could have the same or different definitions.
The process of sending files from point A to point B, usually from a server to a client. The server might implement the J2EE platform, and the client, the J2ME platform.
To transfer data processing tasks to another program or device.
Server that sends requests to another server for processing. WebLogic Server supports proxying of HTTP requests with its HTTPProxyServlet. You can proxy to an instance of WebLogic Server from Netscape and Microsoft Internet Information Server (IIS) through WebLogic Server's Netscape Server Application Programming Interface (NSAPI) and Internet Server API (ISAPI) plug-ins. The use of a proxy server is invisible to the end user.
See also hypertext transfer protocol (HTTP) and proxy.
Value provided by a certificate authority that, combined with a private key, can be used to encrypt and decrypt messages.
Algorithm for encrypting or decrypting data with a public or private key. A private key is typically used to encrypt a message digest; in such an application, the public key algorithm is called a message digest encryption algorithm. A public key is typically used to encrypt a content-encryption key, or session key; in such an application, the public key algorithm called a key-encryption algorithm. An example of a public key algorithm is RSA.
Technique in which a pair of asymmetric keys—a public key and a private key—is used for encryption and decryption. The public key is made public by distributing it widely. The private key is never distributed; it is always kept secret.
Extension of public key encryption technology developed for protection of a WebLogic Server environment. Public key encryption is used, in this extension, to establish end-to-end digital signing and data privacy between WebLogic Server and application clients. It complies with the PKCS-7 standard.
Business process conducted between trading partners. A public process is part of a formal contract between trading partners that specifies the content and semantics of message interchanges between them. When the RosettaNet business protocol is used, the business process is a partner interface process (PIP). For all business protocols, a public process is implemented by means of collaborative workflows.
Public-Key Cryptography Standard 7 (PKCS-7)
One of a set of Public-Key Cryptography Standards developed by RSA Laboratories in cooperation with an informal consortium, originally including Apple, Microsoft, Digital Equipment Corporation, Lotus, Sun and MIT.

To choose one of WebLogic Server's built-in replica handlers, set various flags for RMI and EJB compilation; these flags determine how the replica handler treats service characteristics such as failures and retries, and server affinity.
See also remote method invocation (RMI), replica-aware stub, and stub.
Wrapper that delegates its calls to a service instance. It has intelligence about how to deal with load-balancing and failover situations in which a service might be handled transparently by another server.

Implementation of business logic and presentation logic in the Commerce services that shows customers the items they have selected for purchase. Customers can start the payment process from the shopping cart.
Simple Object Access Protocol (SOAP)
Standard rules for formatting an XML message so that it can be interpreted by different Web services. It provides a means by which applications can communicate with each other over the Internet, independent of platform. Unlike OMG's IIOP, SOAP piggybacks a DOM onto HTTP (port 80) in order to penetrate server firewalls, which are usually configured to accept port 80 and port 21 (FTP) requests. SOAP relies on XML to define the format of the information and then adds the necessary HTTP headers to send it.
See also Internet Interoperability Protocol (IIOP), distributed object model (DOM), hypertext transfer protocol (HTTP), and extensible markup language (XML).
Server-side representation of a remote object that takes serialized requests from a stub, deserializes and unpacks it, and submits it as a method call to be invoked on the object's implementation. The server-side skeleton is responsible for deserializing and unpacking the request from its companion client-side stub.
See also server-side code and implementation.
See Systems Network Architecture (SNA).
See Simple Object Access Protocol (SOAP).
Endpoint of communication to which a name may be bound. The logical end point of a TCP/IP connection. An application accesses a TCP/IP connection through a socket.
WebLogic Portal option available in the JSP templates provided with the Commerce services. By using this option, customers can determine whether they want to have individual items they have purchased shipped to them as soon as those items are available (even if multiple shipments are required), or to have shipment of all items postponed until all items are can be shipped together. After a customer confirms a choice between these approaches, a pipeline commits that choice to the database.

Stand-alone discounts are available in all versions of the E-Business Control Center.
See also BEA E-Business Control CenterTM.
First component of a workflow, which specifies the workflow's triggering properties. The first shape after the start node is the first active component in the workflow.
Object in which application data is stored. Its state may change from one method execution to another. In a clustered environment, both load balancing and failover require stateful objects, because when a server hosting a stateful service fails or balances, the state of the service must accompany the object as it moves to another host.
Java bean that maintains a conversational state on behalf of a specific client. When a conversational state is maintained in a bean, multiple clients can access the bean on separate occasions, and use the information accumulated during the previous occasions, including the last.
Just as you pick up where you left off when continuing a conversation with a coworker from one day to the next, a client and a bean can continue a conversation from one session to the next, when the bean being used is a stateful session bean (that is, when the bean is one that can maintain conversational state).
Therefore a stateful session bean is useful for managing a process through multiple interactions.
Object that saves no application data; it is idempotent. Each operation on the object is independent of all other operations. (Do not confuse this general concept of stateless with the specific definition used in reference to a session EJB.)
Java programming language keyword that defines a variable as a class variable. Classes maintain one copy of class variables regardless of how many instances exist of that class. This keyword can also be used to define a method as a class method. Class methods are invoked by the class instead of a specific instance, and can only operate on class variables.
Structured Query Language (SQL)
Semi-standard language used to manage the tables and records in relational databases. Specifically, you can use SQL statements or queries to create, manipulate, query, update, and delete tables and records. For more information, visit http://www.sql.org.
Client-side representation of a remote object that is used to invoke methods on the implementation of the remote object. Defines the interface to the remote object implementation of an object. The stub is responsible for packaging the client request, serializing it, and shipping it to the companionskeleton on the server side.
See also implementation and skeleton.
Graphical representation, in the WebLogic Integration Studio drawing area, of a workflow node.
XSLT document that describes data transformations (or mappings) to be performed on an XML document. A stylesheet specifies which nodes of an XML document are to be manipulated (using XPath), and which manipulations are to be performed.
Container for related information about a single entity, such as a person. Such information includes the Subject's identities, as well as security-related attributes associated with it (such as passwords and cryptographic keys). Subjects may potentially have multiple identities. The Subject does not represent any of these identities; instead, it is a container for them. Each identity is represented as a Principal within the Subject.
In WebLogic Server security providers, the Subject contains a Principal for the user (WLSUser Principal) and a Principal for each group of which the user is a member (WLSGroups Principals). Custom Security providers may store identities differently.
Permission for a trading partner to participate in a particular role in a specific conversation definition. To send business messages for a role in a conversation, a trading partner must have a subscription to that role. To subscribe, a trading partner must specify its own name, the name and version of the desired conversation, and the role to which the trading partner is subscribing.
Sequence of processes for producing, shipping, and distributing products.

Attribute of a method that returns a value. The term is derived from the fact that a caller to a synchronous method must wait for the called method to return: the caller is synchronized with the method.
Message delivery method whereby B2B integration returns control to the application once the outcome of a message transmission is known. Control is returned to the application after any of the following events occur: acknowledgments are received from all potential destinations; the message times out; or a conversation in which the message was sent terminates.
Mechanism by which connection requests are passed between entities. To achieve a standard system-level pluggability between application servers, such as WebLogic Server and enterprise information systems (EIS), the Connector Architecture defines a standard set of system-level contracts between an application server and an EIS. The EIS side of these system-level contracts is implemented in a resource adapter.
Business process management (BPM) error handler available to every workflow template definition. Unless overridden by a workflow template definition, BPM invokes the system error handler whenever an exception occurs. When called, the system error handler rolls back the specified transaction and throws an exception to the client application.
Message placed in the local log to record WebLogic Integration activity. An example is a message indicating the inability to deliver a trigger item because B2B integration has terminated.
Type of cooperative work among multiple trading partners in which all participants are aware of all other participants from the beginning of the business relationships. In such an arrangement, the business relationship is ongoing and process changes occur infrequently.

See also Web application (Webapp) and Web service.
Code module through which one company offers online business functionality to another company or software program, usually through a network, such as the Internet. A code module that provides a Web service is language-independent, platform-independent, and self-describing.
The location of a Web service may be hard-coded in an application designed to use the service, or it may be identified by the service using UDDI (Universal Description, Discovery, and Integration). Because the service is self-describing, the application that invokes it can determine which functions are available and how to call them.
Web Services Description Language (WSDL)
An XML-based specification markup language used to describe a Web service so that the service can be called by diverse clients. A WSDL is necessary if two different online systems need to communicate without human intervention.
