Is Jive Messanger possible to make HTTP web chat through firewall

I am making a web chat application using jive messenger+xiff. For common situation it works fine but for intranet users they get problem for making socket connection through web because corporate firewall. So is there a way for making jive messenger with any library to make HTTP web chat. I saw some people posting about Punjab and JwChat but do not know how to make them work with jive messenger. I am using windows 2003 with jive messenger built in jetty servlet.

Thx.
