I have few SOAP Webservices which are defined in C# as a different solution and I have a GUI Application built in JAVA.
Can anyone provide links to consume those webservices through Java Application with description?
I'm assuming that you are creating the soap services with something like WCF? Then that means that you have some WSDL at the soap end-point.
Useful links: Where is wsdl file in WCF service
You could use JAX-WS to autogenerate a java client out of the WSDL exposed by the soap services end-point (the underlying implementation is irrelevant whether it is on .Net or any other framework).
