I think I understand your scenario:
        You want to invoke a service and have the result sent to (and 
processed by) another service.

I have a couple of comments based on this:
 1. For that scenario you don't need a 2-way client as there will never be 
a response to the client (it should go to the ping service).
 2. The scenario isn't currently supported by Axis2. I proposed a patch to 
support it a while ago that received some objections and I've been meaning 
to follow it up. This has reminded me about it and I'll follow up soon.
 3. There is a ReplyTo based scenario which Axis2 does support, namely an 
asynchronous 2-way invocation where the response is sent back to the 
initiating client on a second connection though I don't think this matches 
what you're trying to do. (I think its what you've based your client on)
