Sniffing IP# On Java Based Chats

I am new to all this, and I was wondering if there was a way to sniff IP# on a Java based chat, something like Parachat. I have tried a couple of packet sniffers and all that, but I'm unable to get an IP# of the people on chat. Is there any way of gettng an IP# of a chatter and not the IP# of the chat room itself. Here's what a Parachat chatroom looks like.
