[vtkusers] java + sockets

[Christopher M. Navarro]

I'm trying to send a string across a socket from a java client to a c++ 
server and I'm not sure what I'm doing wrong.  Here is a snip of code:

in java:
vtkSocketController contr = new vtkSocketController();
contr.Initialize();
vtkSocketCommunicator comm = new vtkSocketCommunicator();
String test = new String("test");

if(comm.ConnectTo(hostname,port) ==0) {
// do the right thing if the connect failed
}
if(comm.Send(test, 4, 1, 33) == 0) {
// do the right thing if the send failed
}

in c++:

char msg[4];
if(comm->Receive(msg, 4, 1, 33) == 0) {
// do the right thing if it failed
}

This works fine but when I try
cout << msg[0];  

The program crashes.  Any ideas as to what I'm doing wrong?
