I´m very sorry, I don´t explain my problem well. You are right, I´m trying to do a dual channel non-blocking client and the CodeGen generates my CallbackHandler, I´m using ADB also.
The problem it´s that when I´m trying to obtain the result for: callbackReceiver.receive(messageContext) I have an exception. java.lang.NullPointerException at org.apache.axis2.util.CallbackReceiver.receive(CallbackReceiver.java:32) I have seen that the method receive in org.apache.axis2.util.CallbackReceiver makes RelatesTo relatesTO = messageCtx.getOptions().getRelatesTo(); String messageID = relatesTO.getValue(); And in my case relatesTO is null so messageID throws an exception and I can´t obtain the result. So, callback in never onComplete and the CallbackHandler is never call. My client works fine but I don´t know how to obtain the webservice response. Thank you very much.

Several things here don't make sense to me here. Perhaps with some more info maybe we can help: 1) You say you are using codegen with a hashMap - but there is no wsdl type for java.util.HashMap . 2) CodeGen generates its own *CallbackHandler.java , right? The code you are showing looks like its from the code gen stub. What you really need to do, IMHO, is implement your *CallbackHandler.java methods and invoke your Stub.start* (at least using xmlbeans, probably the samething for ADB) methods that receive the argument of *CallbackHandler .
