Java Web service client applications use a proxy client to interact with the Web services APIs.
A proxy client for Java™ Web services contains a number of Java Bean classes that the client application calls to perform Web service requests. The proxy client handles the assembly of service parameters into SOAP messages, sends SOAP messages to the Web service over HTTP, receives responses from the Web service, and passes any returned data to the client application.
Basically, therefore, a proxy client allows a client application to call a Web service as if it were a local function.
In the IBM® Web services environment, there are two ways to generate a proxy client:
Other Java Web services development environments usually include either the WSDL2Java tool or proprietary client application generation facilities.
