As far as I know there is no way to allow a regular user to open a port <
1024. The request from the client doesn't make a lot of sense - perhaps it
could be explained to the client that it is more secure to run the Java
application on a non-privileged port. Or the application could be recoded
to do something like what the Apache web server does - start as root to
bind to the port, then switch to a non-root user. I have no idea if that is
possible for a Java app.
Or, maybe sudo could be used to allow a regular user to start the
application - in this case though, the application would still be running
