=head1 NAME
POE::Component::Jabber::J14 - connect to the jabberd14 router as a service
=head1 SYNOPSIS
PCJ::J14 is a Protocol implementation that connects as a service to a jabberd14
server.
=head1 DESCRIPTION
PCJ::J14 authenticates with the server backend using the method outlined in
XEP-114 (Jabber Component Protocol)
[http://www.xmpp.org/extensions/xep-0114.html]
=head1 METHODS
Please see PCJ::Protocol for what methods this class supports.
=head1 EVENTS
Listed below are the exported events that end up in PCJ's main session:
=over 2
=item set_auth
This event constructs and sends the <handshake/> element for authentication.
=item init_input_handler
This is out main entry point that PCJ uses to send us all of the input. It
handles the authentication response.
=back
=head1 NOTES AND BUGS
This only implements the jabber:component:accept namespace (ie. the component
initiates the connection to the server).
Also be aware that before this protocol was documented as an XEP, it was widely
implemented with loose rules. I conform to this document. If there is a problem
with the implementation against older server implementations, let me know.
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.
