Chapter 10. JAX-RPC Service Endpoints
A JAX-RPC service endpoint (JSE) is the simplest way to create a Web service in J2EE. In fact, it's so simple to create basic endpoints with JSEs that you will probably be reluctant to try anything else. Of course, there is a lot more to JAX-RPC than JSEs, but this chapter will give you enough information to get up and running with your first Web service.
A Simple JSE Example
Writing the code for a JSE is extremely simple. To create a JSE all you do is define an endpoint interface and an implementation class. An endpoint interface defines each of the Web service operations that your JSE will support in the form of a Java method. The implementation class implements these endpoint methods. For example, Listing ...
