# POE::Component::Jabber::XMPP(3pm)

connect using the XMPP Jabber protocol

## NAME

POE::Component::Jabber::XMPP - connect using the XMPP Jabber protocol

## SYNOPSIS

This is a Protocol implementation for the specifics in the XMPP protocol during connection initialization.

## DESCRIPTION

PCJ::XMPP provides all the mechanisms to negotiate TLS, SASL, resource binding, and session negotiation that PCJ needs to successfully establish an XMPP  connection. In essence, it implements XMPP Core and a smidgeon of XMPP IM.

## METHODS

Please see PCJ::Protocol for what methods this class supports.

## EVENTS

Listed are the exported events that make their way into the PCJ session:

- set\_auth

  This handles the initial SASL authentication portion of the XMPP connection.

- init\_input\_handler

  This is our entry point. This is what PCJ uses to deliver events to us.

- build\_tls\_wheel

  If TLS is required by the server, this is where that negotiation process  happens.

- challenge\_response

  This handles the subsequent SASL authentication steps.

- binding

  This handles the resource binding

- session\_establish

  This handles session binding.

## NOTES AND BUGS

Currently, only DIGEST-MD5 and PLAIN SASL mechanisms are supported. Server  implementations are free to include more strigent mechanisms, but these are the bare minimum required. (And PLAIN isn't /really/ allowed by the spec, but it is included because it was a requested feature)

The underlying backend has changed this release to now use a new Node implementation based on XML::LibXML::Element. Please see POE::Filter::XML::Node documentation for the relevant API changes.
