I agree with Tom.
If your application has to be single threaded, and a listener
has to listen on a port all the time for coming events,
how about the non-blocking socket I/O in Java SDK 1.4?
The non-blocking package allows application to continue
its other operation and handle the socket I/O at a later time,
and allows application to handle multiple socket connections
in a single threaded application. However, your listener has to
be socket listener, and the connection client has
to be socket application.
