Document Scope and Audience
This document is a resource for system administrators who want to configure and manage a WebLogic Messaging Bridge as a forwarding mechanism between any two messaging products—thereby providing interoperability between separate implementations of WebLogic JMS, or between WebLogic JMS and another messaging product. It also contains information that is useful for business analysts and system architects who are evaluating WebLogic Server or considering the use of WebLogic Server JMS for a particular application.
It is assumed that the reader is familiar with programming in Java Platform, Enterprise Edition (Java EE) and JMS concepts. This document emphasizes the value-added features provided by WebLogic Server and key information about how to use WebLogic Server features and facilities to configure and manage a messaging bridge.
Guide to This Document
This chapter, Introduction and Roadmap, describes the organization and scope of this guide, including new features and related documentation.
Understanding the Messaging Bridge, describes basic WebLogic Messaging Bridge resources, such as resource adapters and destinations.
Designing a Messaging Bridge, explains design options and other prerequisite considerations for configuring a WebLogic Messaging Bridge.
Interoperating with Different WebLogic Server Releases or Foreign Providers, explains the interoperability guidelines that apply when using the messaging bridge to access JMS destinations on different releases of WebLogic Server and in other WebLogic Server domains.
FAQs: WebLogic Messaging Bridge, provides answers to frequently asked questions (FAQs) for the WebLogic Messaging Bridge.
For information on topics related to configuring and managing a messaging bridge, see the following documents:
Administering JMS Resources for Oracle WebLogic Server is a guide to configuring and managing WebLogic JMS resources.
Developing JMS Applications for Oracle WebLogic Server is a guide to developing WebLogic JMS applications.
Tuning Performance of Oracle WebLogic Server provides information on how to monitor performance and tune the components in a WebLogic Server.
Developing Applications for Oracle WebLogic Server is a guide to developing WebLogic Server applications.
Deploying Applications to Oracle WebLogic Server is the primary source of information about deploying WebLogic Server applications.
Developing Resource Adapters for Oracle WebLogic Server contains information on WebLogic resource adapters and the WebLogic Server implementation of the Java EE Connector Architecture.
Samples and Tutorials for the JMS Developer
In addition to this document, Oracle provides a variety of code samples and tutorials for JMS developers. The examples and tutorials illustrate WebLogic Server JMS in action, and provide practical instructions on how to perform key JMS development tasks.
Oracle recommends that you run some or all of the JMS examples before developing your own EJBs.
Avitek Medical Records Application (MedRec) and Tutorials
MedRec is an end-to-end sample Java EE application shipped with WebLogic Server that simulates an independent, centralized medical record management system. The MedRec application provides a framework for patients, doctors, and administrators to manage patient data using a variety of different clients.
MedRec demonstrates WebLogic Server and Java EE features, and highlights Oracle-recommended best practices. MedRec is optionally installed with the WebLogic Server installation. You can start MedRec from the
\user_projects\domains\medrec directory, where
ORACLE_HOME is the directory you specified as the Oracle Home when you installed Oracle WebLogic Server. See Sample Applications and Code Examples in Understanding Oracle WebLogic Server.
MedRec includes a service tier comprised primarily of Enterprise Java Beans (EJBs) that work to process requests from web applications, web services, and workflow applications, and future client applications. The application includes message-driven, stateless session, stateful session, and entity EJBs.
JMS Examples in the WebLogic Server Distribution
WebLogic Server optionally installs API code examples in
WL_HOME is the top-level directory of your WebLogic Server installation. Start the examples server and obtain information about the samples and how to run them from the WebLogic Server Start menu.
Additional JMS Examples Available for Download
Additional API examples are available for download at the Oracle Technology Network at
http://www.oracle.com/technology/index.html. These examples are distributed as.zip files that you unzip into an existing WebLogic Server samples directory structure. You build and run the downloadable examples in the same manner as you would an installed WebLogic Server example.
