JAX-RPC

Encyclopedia : J : JA : JAX : JAX-RPC

JAX-RPC (Java API for XML-based RPC) allows invoking from a Java application a Java based Web Service with a known description while still being consistent with its WSDL description. It can be seen as Java RMIs over Web Services.

It works as following:

A Java program invokes a method on a stub (local object representing the remote service)
The stub invokes routines in the JAX-RPC Runtime System (RS)
The RS converts the remote method invocation into a SOAP message
The RS transmits the message as an HTTP request

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.
