Your *ServiceStub.java is auto generated and should not be modified.
What you need to do is implement your *Callback.java and _not_ mess
around with CallbackReceiver - much in the same way as you implemented
your *Skeleton.java - the difference being that the *Callback.java is
client side and used for asyc operations. Then use this *Callback.java
as you would the Callback.java class shown in the user guide. Its been
a few months since I did this, but last I checked it does work.

Hi,
The source code in my *ServiceStub.java is:
org.apache.axis2.context.MessageContext _messageContext = new
org.apache.axis2.context.MessageContext();
_messageContext.setEnvelope(env);
_operationClient.addMessageContext(_messageContext);
Callback callbackClient= new Callback() {...};
_operationClient.setCallback(callbackClient);
_operationClient.getOptions().setUseSeparateListener(true);
_operationClient.getOptions().setTransportInProtocol(Constants.TRANSPORT_HTT
P);
CallbackReceiver _callbackReceiver= null;
if (_operations[0].getMessageReceiver() == null &&
_operationClient.getOptions().isUseSeparateListener()) {
_callbackReceiver = new CallbackReceiver();
_operations[0].setMessageReceiver(_callbackReceiver);
}
_operationClient.execute(false);
_operations[0].getMessageReceiver().receive(_messageContext);
I don´t know how to obtain the result, I do
_operations[0].getMessageReceiver().receive(_messageContext) but it isn´t
right because _messageContext contain the message that I use to call the web
service not the response, but I don´t know where to find the messageContext
with the response. Can you help me? And that is why I haven´t a relatesTo
value.

Asunto: Re: [Axis2] Non-blocking dual client
Hi Marta,
If there is an NPE, I will fix it.
But I'm sorry I'm missing something here. You *must* have a relatesTo
value, when you do a dual channel, non-blocking invocation. So what do
you mean by saying "in my case relatesTO is null"?
