Turning a Java class into a web service is very straightforward in Axis2. Once you know how to write a services.xml file correctly, you can create more complex applications rather than just POJOs. Deploying a service is just a matter of creating a service archive file and dropping it into the services directory in the Axis2 repository. WSDL's first approach is the easiest way of creating a service since Axis2 has inbuilt support for code generation and it has a set of tools to make the job even easier.
In this chapter, we discussed how to convert a simple class file into a web service and how to access that in a REST manner. We discussed what happens when the service becomes a little complex by adding a package name. We also discussed how to use the archive-based deployment mechanism. Finally, we briefly discussed the contract first approach.
In the next chapter, we will discuss how to extend Axis2's core functionality and provide additional service quality using the Axis2 module.
