Configuring and Managing the WebLogic Messaging Bridge

Introduction and Roadmap

The following sections describe the contents and organization of this guide—Configuring and Managing the WebLogic Messaging Bridge:

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 J2EE 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, as well as 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.
Tuning WebLogic Message Bridge, provides information on how to tune a messaging bridge to achieve improved performance.

Samples and Tutorials for the JMS Developer

In addition to this document, BEA Systems 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.

BEA 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 J2EE 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 J2EE features, and highlights BEA-recommended best practices. MedRec is included in the WebLogic Server distribution, and is accessed from the Start menu on Windows machines. For Linux and other platforms, start MedRec from the WL_HOME\samples\domains\medrec directory, where WL_HOME is the top-level installation directory for WebLogic Platform.

MedRec includes a service tier comprised primarily of Enterprise Java Beans (EJBs) that work together 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 9.1 optionally installs API code examples in WL_HOME\samples\server\examples\src\examples, where 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 9.1 Start menu.

Additional JMS Examples Available for Download

Additional API examples for download at http://dev2dev.bea.com/code/index.jsp. 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.

New and Changed JMS Features in This Release

Many new Messaging Bridge features were introduced in WebLogic Server 9.0. For information on these features see the What's New in WebLogic Server 9.0 section of the WebLogic Server Release Notes.
