A friend of mine and I are attempting to play pc multiplayer over network. I host. He connects to my IP. The chat window comes up with a single message on his end. Neither of our games acknowledge the other has done anything. There is no java error that arises. Just nothing but a chat message on the non-host side. This happens to whoever is not the host. I have seen the message come up for those who have java errors come up, but neither of us get any java errors. We just type and nothing is happens.
We are both on release 1.6.56 on pc.
Any info or insight would be appreciated.

my knowledge of java is limited, does anyone at least know what this error is?

The channel being null means you weren't connected when it tried to send. Was there an error on the other side?
