Socket data send-receive problem

I hv J2ME client application and vb.net socket server application communicating over sockets. Client connection is made successfully but cant send data to server. When I exit from client application then server application receives those data. (application works pretty fine on emulator but on real device gives above problem)

WTK Sample application gives same problem when I tried.

Any idea abt this problem ? gr8 ful if u have some working code.
