[JDEV] XDB (external modules)

[David Waite]

Server modules must authenticate with the server. You send a
stream:stream header with appropriate namespace (jabber:component:accept
in this case, I believe), then the server responds with its own with an
'id' attribute embedded. Do a SHA1 of (id + secret) to get the handshake
value, then send this in a <handshake> tag. The server will respond with
an empty handshake tag if you authenticated correctly, and you are in.

For a Java example, see JabberBean (the DNS server for jabberbeans.org
seems to be having problems, try jabberbeans.sourceforge.net)
org.jabber.jabberbeans.serverside.Launcher contains the logic for
accept, connect, and exec. There is some code which uses this in the
src/jabberbeans-tests dir as well. (HelloWorldTransport)
