I am starting Java network programming for the first time although I have
experience in Java itself and socket programming in C++.  I have an IM
server already running which I use to communicate with C++ clients and that
all runs fine.  Now I want to develop a Java client but am having problems.
When I connect the socket then try to get the input stream my program just
hangs.  The code is below, if anyone can tell me why this might happen, I
would appreciate it.

Another point is that, I want to send actual bytes on the line and receive
actual bytes, what type of input/output stream should I be using?

Thanks
Allan
