using websocket within ofbiz

Hi all,

I've been trying to utilize the websocket in current trunk of ofbiz.
Make new component in hot-deploy, using the exact chat example from tomcat
and include the Java class. It can be compiled and ant start run without
any problem, but my browser console keeps telling me that ws connection
cannot be made.

I have read the discussion from Jacopo in Tomcat mailing list too, tried to
add the listener in web.xml and still my browser cannot make ws connection
to my ofbiz instance.

Have you guys any experience on this issue?

Thanks in advance!
