Overview
Introduction to WebLogic Server Process Edition
WebLogic Server Process Edition provides you with the technologies and tools you need to effectively service-enable your existing resources, create composite services using process-driven development, and extend these composite services to interact with other applications and technologies. Each of these phases allows you to take distinct measurable steps that are effective for both project and enterprise level architectures.
The following sections introduce the key features of WebLogic Server Process Edition, detail the WebLogic options available when you purchase a WebLogic Server Process Edition license and provide a brief overview of WebLogic Server Process Edition:
Access resources such as databases or other resources.
Encapsulate logic for reuse in other applications.
Modularize logic you want to keep separate from other application code.
Use Java 5 annotations to set control properties.
Provide mechanism to encapsulate business logic and to access enterprise resources such as databases, web services, EJBs, JMS message queues, and legacy applications using system controls.
Provide mechanism to fully customize access to a resource or encapsulate some application functionality using custom controls. You can design a custom control to do any task in an application.
Build, view, and change process models, with drag-and-drop graphical construction of complex composite service scenarios and two-way editing between Design and Source views.
Execute sophisticated Web service orchestration scenarios using composite process driven services.
Automatically accessible as a Web service, can easily invoke and respond to other Web services, and can be exported to Business Process Execution Language (BPEL).
Built-in support for asynchronous communication, lifecycle events, security, transactions, etc.
Supports proven process operations such as Synchronous and Asynchronous Communication, Branching, Nesting, Looping, Parallelism, Grouping, and Exception Handling.
Based on Process Definition for Java (PD4J-JSR 207), providing a seamless convergence between graphical representation of process flows in XML and Java for logic execution.
View process type information and locate specific processes for configuration.
View or update process type properties, the security policies for a process, and the selectors used to dynamically set control attributes for a Process or Service Broker control.
Activate or deactivate a non-versioned process.
Configure the activation time for a newly deployed process version, or rollback to a previous version.
View an interactive or printable process type graph.
View summary statistics that reflect system health and the summary or detailed status for selected instances.
Terminate or suspend instances, resume previously suspended instances, or unfreeze frozen instances.
Build for Integration
Unified Development Environment and Run-Time Framework
Use a single tool, runtime framework, and programming model to orchestrate all enterprise services including custom Java Controls, Applications, and Web services.
Easily produce and manage custom-fit enterprise portals through interoperability with Web applications and BEA WebLogic Portal.
Switch from writing code to immediately testing applications with one-button deployment, integrated debugger, and automated test harness.
Support latest standards including SOAP 1.2, WSDL 1.2, UDDI 2.0, and WS-Security.
Annotations based on JSR-175 standards.
XML productivity tools based on emerging XML Beans, XML Schema, and XQuery standards.
Comprehensive support for Enterprise Java Bean (EJB) development and deployment, including design views for session and entity beans.
Implement Web applications based on the Apache open-source Struts framework.
Support for BPEL export for cross platform interoperability.
An Enterprise Class Foundation
Industry Leading Application Server
Robust J2EE-certified application server functionality provides the essential capabilities and underlying infrastructure for enterprise-class applications: Security, system management and monitoring, failover via clustering, performance, scalability, transactions.
Native clustering that is completely transparent to the application.
Proven scalability and reliability in the most demanding enterprise environments.
Ensures that users experience no service interruption in mission critical applications. Use of in-memory replication to scale large clusters while ensuring high availability.
Allows reuse of different types of connections required to establish communications with clients, to databases, application adaptors, and message factories.
Delivers proven performance, scalability, flexibility, clustering, security, transaction management, and reliability to meet enterprise needs with confidence.
Installation
There is no separate installation procedure for WebLogic Server Process Edition. The availability of features is dependent on the WebLogic Platform product components and licenses installed.
When you install WebLogic Server, Workshop, and WebLogic Integration (the components of WebLogic Platform on which WebLogic Server Process Edition functionality depends), a development license is included that enables a complete development framework for the installed components.
To enable the WebLogic Server Process Edition capabilities for production, you must have a WebLogic Server Process Edition production license installed.
In the development environment, the features available in the WorkSpace Studio IDE are dependent on:
The WebLogic Platform components installed.
The type of domain in which the server is running.
If you have installed WebLogic Integration and are running the server in a WebLogic Integration domain, the WorkSpace Studio IDE not only provides access to the controls and other functionality supported by WebLogic Server Process Edition, it also provides access to WebLogic Integration features that are not supported by the WebLogic Server Process Edition production license. To ensure that no unsupported features are used, you must restrict the development environment by using only the features as described in the following section.
Mode
The WebLogic Server Process Edition production license is enforced at run time. However, as described in the previous section, the functionality available by default in the development environment is a superset of the functionality supported by the WebLogic Server Process Edition production license. To ensure that the functionality available is consistent with the functionality supported by the production license, WorkSpace Studio now supports the WebLogic Server Process Edition mode of operation.
Follow the steps to set the WebLogic Server Process Edition mode
After starting WorkSpace Studio, set the mode by selecting Window > Preferences...
The Preferences... dilog box is displayed as shown in the following figure
Click Weblogic Integration, and select the Set Weblogic Process Edition Mode check box.
Click Apply
Click OK.
If you are developing applications for a WebLogic Server Process Edition production environment, you must select the WebLogic Server Process Edition mode in WorkSpace Studio, before building any applications to avoid building applications that are not supported by your license at run time. Once you make this change, the new mode of operation is saved as an environment setting.
Notes:
When you try to upgrade a 8.x or 9.x application that has unsupported controls, the IDE does not show any error during the upgrade process regardless of the WebLogic Server Process Edition mode. However, when deployed, the application fails.
Note:
If an unsupported control is created before switching to the Process Edition mode, the IDE continues to enable such controls. But, the application fails at run time.
Note:
Also, when copying the unsupported controls from a different workspace to the current workspace, where Process Edition is enabled, the IDE does not show any error. However, the application fails to deploy.
Features
The WebLogic Server Process Edition production license provides business process management, data transformation, and process monitoring capabilities that are available in WebLogic Integration, in addition to all the capabilities of WebLogic Server Premium. WebLogic Server Process Edition does not include the Message Broker, WorkList, application integration framework, and trading partner integration capabilities that are available in WebLogic Integration. (For a description of the various offerings, see Licensing.)
The following table details the differences between WebLogic Server Process Edition and WebLogic Integration.
The WebLogic Platform contains numerous component products, as shown in the following figure. You can use a combination of these components, or just use an individual component, to build an application.
Figure 1-1 WebLogic Platform Component Products
BEA WebLogic Server, the industry-leading J2EE application server, provides the critical infrastructure needed to develop integrated solutions, including security, transaction management, fault tolerance, persistence, and clustering.
Leveraging WebLogic Server as the underlying deployment environment, WebLogic Integration uses Web services to integrate distributed systems inside and outside an organization and utilizes the BEA WorkSpace Studio framework to simplify application development.
WebLogic Integration works seamlessly in the WorkSpace Studio environment. WebLogic Integration uses the power of WorkSpace Studio to provide a robust set of tools to develop and extend integration applications. WebLogic Integration provides graphical tools you use to edit your business processes, and human interaction task plans. These tools are available in the same WorkSpace Studio environment as your controls, Web services, and portal-building tools.
WebLogic Server Process Edition contains an IDE framework based on Eclipse 3.1.2.
