Java ES system service components provide the infrastructure services needed to support distributed enterprise applications. The Java ES system service components are described in the following sections:
Sun Java System Access Manager (Access Manager) provides an infrastructure for an organization to administer the processes used to manage the digital identities of customers, employees, and partners who use their web-based services and non web-based applications. Because these resources might be distributed across a wide range of internal and external computing networks, the attributes, policies and entitlements are defined and applied to each identity to manage access to these technologies.
The Java ES installer provides Access Manager as a single installable component. If needed, the following Access Manager subcomponents can be installed separately:
Identity Management and Policy Services Core. Provides the means for creating and managing user identities, and for defining and evaluating policies that provide access to Java ES resources based on users’ identities. This subcomponent also includes the Access Manager SDK and the Delegated Administrator (see Sun Java System Delegated Administrator 6 2005Q4) subcomponents.
Access Manager SDK. Provides a remote interface to Access Manager. This subcomponent needs to be installed on any computer hosting a Java ES component that accesses Access Manager remotely.
Access Manager Administration Console. This graphical interface consolidates identity services and policy management and provides a single interface for users to create and manage user accounts, service attributes, and access rules in the Directory Server.
Common Domain Services for Federation Management. Enables users to use a single identity to access applications offered by multiple affiliated service providers.
Sun Java System Application Server (Application Server) provides a J2EE-compatible platform for developing and deploying application services and web services. Application Server provides the infrastructure services for interaction between tightly coupled distributed components, including remote method invocation and other runtime services.
The Java ES installer provides Application Server as a single installable component. If needed, the following Application Server subcomponents can be installed separately:
Domain Administration Server. Provides server-side administration functions, such as managing and configuring Application Server and deploying J2EE components and applications.
Application Server Administration Client. Provides graphical administration clients that allow you to manage and configure Application Server installations and hosted applications. The Administration Client also assists with deploying applications.
Command Line Administration Tool. Provides command-line administration clients that allow you to manage and configure Application Server installations and hosted applications. The tool also assists with deploying applications.
Load Balancing Plug-in.
PointBase. Provides an embedded database that can be used for persistence operations.
Sun Java System Calendar Server (Calendar Server) is a scalable, web-based solution that is used for centralized calendaring and scheduling for enterprises and service providers. Calendar Server supports personal and group calendars as well as calendars for resources such as conference rooms and equipment.
The Java ES installer provides Calendar Server as a single installable component.
Sun Java System Directory Server (Directory Server) provides a centralized directory service for your intranet, network, and extranet information. Directory Server integrates with existing systems and acts as a centralized repository for the consolidation of employee, customer, supplier, and partner information. You can extend Directory Server to manage user profiles and preferences, as well as extranet user authentication.
The Java ES installer provides Directory Server as a single installable component.
Sun Java System Instant Messaging (Instant Messaging) enables end users to participate in instant messaging and chat sessions, to send alert messages to each other, and to share group news instantly. Instant Messaging is suitable for both intranets and the Internet, and supports interaction with other instant messaging providers.
The Java ES installer provides Instant Messaging as a single installable component. The following Instant Messaging subcomponents can be installed separately:
Instant Messaging Server Core. Includes server and multiplexor software.
Instant Messaging Resources.
Access Manager Instant Messaging Service.
Sun Java System Message Queue (Message Queue) is a standards-based solution to the problem of inter-application communication and reliable message delivery. Message Queue is an enterprise messaging system that implements the Java Message Service (JMS) open standard.
In addition to being a JMS provider, Message Queue has features that exceed the minimum requirements of the JMS specification. With the Message Queue software, processes running on different platforms and operating systems can connect to a common Message Queue service to send and receive information. Application developers are free to focus on the business logic of their applications, rather than on the low-level details of how their applications communicate across a network.
Message Queue is available in two editions:
Enterprise Edition (default). Provides support for multi-broker message services, HTTP/HTTPS connections, secure and scalable connections, client connection failover, and client support for the C language. This edition is best suited to deploying and running messaging applications in a large-scale production environment.
Platform Edition. Provides basic JMS support, and is best suited to small-scale deployments and development environments
The Java ES installer provides Message Queue Enterprise Edition and Message Queue Platform Edition as separately installable components.
Sun Java System Messaging Server (Messaging Server) is a powerful, standards-based Internet messaging server for both enterprises and service providers. Designed for high-capacity, reliable message handling, Messaging Server consists of several modular, independently-configurable components that provide support for several e-mail protocols.
The Java ES installer provides Messaging Server as a single installable component. However, after installation, each Messaging Server instance can be configured to provide any of a number of different messaging services, in effect representing the following set of Messaging Server subcomponents:
Message Store. Provides message storing and retrieving.
Message Transfer Agent (MTA). Supports the sending of emails by handling SMTP connections, routing emails, and delivering messages to the proper message stores. Can be configured to deliver email to internal storage (inbound) or to external mail stores (outbound).
Message Multiplexor (MMP). Supports the retrieving of emails by accessing the message store (or a set of stores) for email clients, using either IMAP or POP protocols.
Message Express Multiplexor (MEM). Supports the retrieving and sending of emails by web-based (HTTML) email clients.
Sun Java System Portal Server (Portal Server) is an identity-enabled portal server solution. Portal Server combines key portal services, such as personalization, aggregation, security, integration, and search. Mobile access, a subcomponent of Portal Server, provides wireless access to the Portal Server from mobile devices, such as mobile phones and personal digital assistants.
The Java ES installer provides Portal Server, including mobile access, as a single installable component.
Sun Java System Service Registry (Service Registry) is a repository that serves as both a web services (UDDI) registry and an enterprise business XML (ebXML) registry for supporting web Service-Oriented Architecture (SOA) applications. The UDDI registry is used to register and discover web services and the ebXML registry is used to store and manage the information artifacts needed to support business process integration. These artifacts include metadata such as XML schema, business process rules, web service access controls, version controls, classifications schemes, and so forth.
Sun Java System Web Server (Web Server) is a multi-process, multi-threaded, secure web server built on open standards. Web Server provides high performance, reliability, scalability, and manageability for any size enterprise. Web Server supports a wide range of web software standards, including JDK 1.4.1, Java Servlet 2.3, JavaServer PagesTM (JSPTM) 1.2, HTTP/1.1, PKCS #11, FIPS-140, 168-bit step-up certificates, and various other security-based standards.
The Java ES installer provides Web Server as a single installable component.
