The problem is in the Axis2FlexibleMEPClient's "send(MessageContext smc)"
method.
Line 80 - ac.addService(axisAnonymousService);
Shouldn't we remove the service with the same name before introducing the new
service.
I suggest a simple hack, for the time being.
if(ac.getService(axisAnonymousService.getName())!=null)
ac.removeService(axisAnonymousService.getName());
ac.addService(axisAnonymousService);
Some other better way is also welcome!
