[MOBY-dev] jMoby: Asynchronous service invocation problems

[Paul Gordon]

Hi Luke,

MobyRequest is my code. I'll look into the error handling for you.  For 
clarification of others on the list, he's making a client call, not a 
server side call.  jMoby supports this through MobyRequest (though it 
seems flakey if there's exceptions by Luke's analysis).
