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>

Chapter 9. The Client API

Web service is one of the commonly used approaches for applications integration (composition), when integrating applications; an application can act as either a consumer (client) or a producer (server). A web service framework should be able to deploy services as well as access the services. So far, we have discussed the deployment side of it. Thus, in this chapter, we will focus on the client side and how to use Axis2 to access remote services. In high level, Axis2 runtime does not differentiate between the client side and the server side. Moreover, it uses the same execution framework at the server side as well as the client side. As we already discussed, in the server side, we have services. Thus, to keep the symmetry in the client side as well, Axis2 creates a dummy service when we use the client API. In this chapter, we will look at the various aspects of the client API, with the example use case.

In this chapter, we will discuss most of the commonly used APIs...
