Facebook with Strophe and punjab

Question

Hi,

I am new to xmpp.I created my own ejabberd server and tried to implement facebook chat through it, but it is giving the response as " remote connection failed". I also tried with punjab but not successful. Can anyone please tell me the configuration settings to be modified or added in ejabberd or punjab. I tried using "chat.facebook.com" as host name and 5222 as port but I m not sure about where to set these values in my configuration files.Can anyone solve this issue??

Thanks, Ramya
