On iPhone, I am running an app with AsyncUdpSocket library to take care of UDP networking. I have tested it. I can send UDP packet from my iPhone to a server that runs Java program accepting UDP correctly. However, when it is the other way around, Java program's UDP message doesn't get through to iPhone.

I have gotten as far as setting the background of the table view to "clear" with the hopes of showing a static image ...
