I´ve seen that I can define a stateful webservice by setting the session feature in the web service definition. But I don´t know how to use this in my Web Dynpro application.
I´ve written a stateful session bean and generated a "stateful" web service for this. The session bean increases a counter each time it is invoked.
In my Web Dynpro app. I created a model for that web service. As a result the "Use HTTP cookie-based session" option is selected in the logical port definition of the model.
In a view I use this model in the following way:
Request_TestWSViRpc_getCounter req = new Request_TestWSViRpc_getCounter();
In an action that is bound to the click event of a button:
When executing my Web Dynpro app. and pressing the button I expect to get the increased counter with each hit. But I allways get a "1".
