Chapter 10. Using WebLogic JMS

The Java Message Service (JMS) specification defines a standard set of interfaces for accessing messaging systems. WebLogic Server provides an enterprise-class messaging system that completely supports the JMS APIs. In addition, WebLogic Server goes the extra mile to make it easy to use other JMS-accessible messaging systems transparently from your Java EE applications. In this chapter, we begin by giving you a brief review of some key JMS concepts. Next, we jump into a detailed discussion of how the WebLogic JMS provider works. Then, we spend some time talking about WebLogic JMS design considerations. We follow that with a brief discussion of WebLogic JMS programming. Finally, we finish up this chapter with a discussion on integrating external JMS providers with WebLogic Server.

Like the rest of this book, this chapter is not intended as an introduction to either JMS or WebLogic Server's JMS implementation. If you are unfamiliar with the basics of JMS, we suggest that you study the book Java Message Service, Second Edition by Mark Richards, Richard Monson-Haefel and David A. Chappell (O'Reilly, 2009) for a complete treatment of JMS. For more information on WebLogic JMS, please refer to the WebLogic Server JMS documentation at Link 10-1, as listed in the book's online Appendix at http://www.wrox.com.
