Creating a Web Service with JAX-RPC
As discussed earlier, the JAX-RPC specification defines how Web Service clients written in Java can make RPC-style calls on Web Services and how Web Services can be written in Java to receive such calls. The Implementing Enterprise Web Services specification defined in JSR109 describes how such Web Services and Web Service clients can be used as part of a J2EE application. Although it is possible to use other transport mechanisms and interaction styles, the main focus of JAX-RPC is for making synchronous calls on top of the SOAP transport. Hence, the remainder of today will focus on building clients and servers that take part in this type of exchange.
