As per your given example I am exposing a Java Class as web service and generating the Java Proxy Client. But java class is replaced as Interface after generating the Java Proxy Client. So it giving problem as:

Hi Amit,

The metjod mentioned here for generating WS stubs is very primitive. Currently we have lot of mechanisms to do the same.

1) Decide what framework you need for your client (Axis for exmaple)
2) refer to the axis api for ANT script that will help you create a client
3) the ant script generallly takes in “testcase” as a parameter which is automatically create you a JUnit test class.

You can use the JUnit test class for testing your webservice easily.

Amit, I have created a small tutorial of how to invoke a web service using web service proxy client and is available at http://www.albeesonline.com/blog/2008/09/15/invoking-a-web-service-using-web-service-proxy-client/. If you have any questions please let me know.
