Hi Sachin

Which SOAP engine are you using in your application.I have worked with the Axis 1.4 SOAP engine. In Eclipse you can import the axis jar file and set the source and the destination end points for the WSDL and the Client Side Stubs generated from the WSDL. I think there may some mistake in this as the engine you are using is not able to get hold of the WSDL.Check for proper syntax to be used to do this operation.

For the client side exception that you are getting see if you are passing the correct parameter to your webservice.it looks like the SOAP engine is not able to serialize the object or the parameter you are passing.try to always pass non null values to your service or you have to do proper exception handling.
