Java API for XML-based RPC

Java API for XML-based RPC (JAX-RPC) allows a Java application to invoke a Java-based Web service with a known description while still being consistent with its WSDL description. JAX-RPC is one of the Java XML programming APIs. It can be seen as Java RMIs over Web services. JAX-RPC 2.0 was renamed JAX-WS 2.0 (Java API for XML Web Services). JAX-RPC 1 is deprecated with Java EE 6. The JAX-RPC service utilizes W3C (World Wide Web Consortium) standards like WSDL or Web Service Description Language.

It works as follows:

The advantage of such a method is that it allows the Web service to be implemented at server-side as a Servlet or EJB container. Thus, Servlet or EJB applications are made available through Web services.
