I want to write a chat client. I could use RMI for that but I don't want to. Moreover I plan to have a web-interface.
I was reading about XMPP protocol and also the fact that google talk uses it. How can I implement it to write my own chat client, not a client for any other IM service? Is there any library available that could help me implement my own chat service (IM) ?

Multi-User-Chat (MUC) Because MUC rooms are based on XMPP, they can be used to exchange not only plaintext message bodies but a wide variety of XML payloads.
As mentioned above, XMPP works by passing small, structured chunks of XML data between endpoints (clients) via intermediary servers. In other words, if you send a message to your friend using XMPP, that message, as part of an XML document, first travels to a server instead of traveling directly to your friend's device.
The original and "native" transport protocol for XMPP is Transmission Control Protocol (TCP), using open-ended XML streams over long-lived TCP connections. As an alternative to the TCP transport, the XMPP community has also developed an HTTP transport for web clients as well as users behind restricted firewalls.
