Ok, now the problem with the connection is solved: when the server was
listening and I closed the connection, I didn't call ServerSocket.close(),
so the next time the system wouln't let me create the same ServerSocket.

I don't know what JVM version is installed on the target machine. It could
be not the 1.4. Other than that, is not this the very problem.

There is a GUI. The user should be able to interact with it.

This would not be a problem. The read() method would be called from a timer
10 times per second or so.

The problem is that (following the documentation), available() always
returns 0 on some systems, and should not be used in these manners. Then I
tried ready(), but returns false. I would like not to use a separate thread
for the network class, since that would mean adding a lot of extra code.
This app will be used just one time (university project) from my
professor...
Thank you for the help.
