Overview of this book

<p>Web services are gaining popularity and have become one of the major techniques for application integration. Due to the flexibility and advantages of using web services, you want to enable Web service support to your applications. This book is your gateway to learning all you need to know about the Apache Axis2 web service framework and its hands on implementation. <br /><br />Apache Axis2 Web Services, 2nd Edition is your comprehensive guide to implementing this incredibly powerful framework in practice. It gives you precisely what you need to know to develop a detailed practical understanding of this popular, modular and reliable web service framework.<br /><br />This book starts with a short and relevant introduction about the Axis2 1.5 framework and then plunges you straight into its architectural model.</p> <p>Learn to use and develop your own modules. Write a services.xml file so efficiently that you'll be creating more complex applications (rather than just POJOs) in no time.</p> <p>Learn how straightforward it really is to turn a Java class into a web service in Axis2. Experiment with different types of sessions in Axis2. Learn different patterns of Enterprise deployment. Ensure reliability in your web service - a major concern in most enterprise applications - with minimum impact on performance.<br /><br />This book will journey you through all this and more, giving you exactly what you need to learn Axis2 1.5 in the easiest way possible and create secure, reliable, and easy-to-use web services efficiently and systematically.</p>

Other modules


The idea of other modules is optional modules that provide additional functionalities or utilities: for example, modules that need to generate Axis2 services and service proxies. Axis2 does not use these modules at the runtime, and as mentioned earlier, those are only to provide additional features. Axis2 uses them as tooling modules to generate service-side code and client-side code.

  • Code generation: Axis2 provides a code generation tool that generates server-side (skeleton) and client-side code (stub or proxy) along with descriptors and a test case. The generated code would simplify the service deployment and the service invocation. This would increase the usability of Axis2.

  • Pluggable data binding: The basic client API of Axis2 lets the user process SOAP at the XML InfoSet level, whereas data binding extends it to make it more convenient for the users by encapsulating the InfoSet layer and providing a programming language-specific interface.
