In this preface, we'll introduce JBoss, Open Source, and, of course, JBoss ESB. We'll also introduce thinking in Service Oriented Architecture terms, how JBoss ESB can help you, and why JBoss ESB is the best choice for your SOA needs.
This preface is organized into a series of questions and answers. We'll begin at the beginning, the beginning of JBoss, that is.
A comprehensive, practical guide to developing service-based applications using the Open Source JBoss Enterprise Service Bus with this book and ebook
-
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.
What you will learn from this book
-
Install, configure, administer, start and stop the JBoss Application Server (AS) and then deploy JBoss ESB onto JBoss AS.
-
Run the JBoss ESB example "quickstart" sample applications, so that you understand the applications' output, and how to debug the JBoss ESB application failures
-
Build custom JBoss ESB applications with JBoss ESB's out-of-the-box actions or your own action code
-
Use a service registry to provide access to your services and store and access your metadata
-
Integrate your custom application with other applications through the protocols supported by JBoss ESB gateway listeners
-
See how the behavior of services can alter through content-based routing and message transformation
-
Use other JBoss open source projects such as the JBoss AS and JBDS with JBoss ESB to create, deploy, and administer services
-
Integrate existing web services with your applications' services over JBoss ESB
Approach
Part of Packt's Beginner's Guide series, each chapter contains practical examples with step-by-step instructions and plenty of screenshots to guide you through the implementation of JBoss ESB.
Who this book is written for
This book is intended for Java programmers although you don't need previous experience with middleware such as application servers or ESBs.
