I have existing Java code that uses a TCP connection with the
DataInputStream and PrintStream as the input and output mechanisms,
repsectively.  When I tried to compile under JDK 1.1.2, I found out that
these are both deprecated.  When I switched to the new classes that the
JDK documentation suggested for replacing the deprecated ones, the
server could not communicate with the client, and vice versa, though
they connected successfully.  Since then I've tried other classes with
the same problem.  For now I'm keeping the deprecated classes in the
code, so that it works, but I should switch to newer classes as soon as
possible.  Can anyone suggest a class that would work, that they've
already had success with?

Thanks!
