Book Description

A comprehensive, practical guide to developing service-based applications using the Open Source JBoss Enterprise Service Bus

  • Develop your own service-based applications, from simple deployments through to complex legacy integrations
  • Learn how services can communicate with each other and the benefits to be gained from loose coupling
  • Contains clear, practical instructions for service development, highlighted through the use of numerous working examples

In Detail

You may often have wondered if there is a better way to integrate disparate applications than error-prone ""glue code"". JBoss ESB is just that solution as it can help solve common but difficult problems: writing new code that can be re-used and maintained, and integrating together new and old systems. JBoss ESB takes care of routing and processing service requests, leaving you to concentrate on your system's design and development.

The JBoss ESB Beginner’s Guide gets you up and running quickly with JBoss ESB to build your own service-based applications, with enhanced communication and organization. You will learn how to create new applications or to integrate combinations of new and legacy applications. Detailed examples get you creating your own services, and deploying and administering them with other JBoss Open Source tools.

Through hands-on examples, this book shows you how JBoss ESB enables you to design your system as services that are loosely coupled together by sending and receiving messages. Your services can execute your own custom code, or make use of JBoss ESB’s extensive set of out-of-the-box actions to perform specific tasks. The JBoss ESB Beginner’s Guide shows you the tools you can use to build re-usable and maintainable service-based applications with JBoss ESB, and teaches you by example how to use these tools.
