Hi, I'm very new to webservice. Had developed a simple webservice which runs on websphere 5.0 and could be accessed by a client program using axis API. Now I had to deploy the same service to a websphere 4.0 environment. Because of this shift there was a change in the encoding ( because of the lack of compliance with WS-I )so the test client had to be modified. Now I am getting the following error when i run my test client -- "Unable to determine object id from call: is the method element namespaced?" Can anyone please help me out here.
