As I had written you in private mail this is true. I have problems with 
the Tomcat server that hosts this servlet at my Jabber server. But the 
servlet is working, you can install it in your own Java servlet container.

There are two ways to pass a proxy: Polling (then you need the 
JabberPollingServlet or an other implementation if JEP-0025) and to use 
a persistend request (this is supported by the jabberd without 
additional software).

The request you sent in your earlier mail was a polling request, this 
will not work with the plain jabberd even not with telnet. Maybe you did 
a persistend proxy request with your telnet client but this request 
doesn't start with the "0," in the request but just with the "<?xml 
version='1.0'?>" tag.

The major difference between the two methods is that polling uses 
multible HTTP connections and with the other method you need a 
presistend connection through your proxy server (that often does not 
allow this).
