Hi, Ignacio. I managed to get the helloworldws-async sample working. I can see both the request and callback are finished without exceptions.
I had to fix some issues in the core as well as the test case. 1) Replaced some logic on ServiceContract.getCallbackClass() which is java-centric 2) Fixed the wrong usages of operation in the JDKWireService (in some cases, we use the source operation for the target side) 3) Replaced "interface.java" with "interface.wsdl" and fixed some issues in the wsdl file. It's the same workaround as we did on the client side that we have to force the axis2 service to use WSDL interface so that data transformation is triggered. I'll commit the changes and you can verify it. BTW, I'm still seeing the "null repsonse" from the client. Thanks, Raymond
