[jdev] Jabber4r

[Neil Mc Laughlin]

Many thanks for the advice, especially the link to the JEP.

I added the resource to the API call as suggested. That wasn't quite enough,
Apparently a minor patch was required for the current ruby xml parser. This
is done by the second require statement. It's still a bit rough round the
edges, but it does work now.

Purely for the record, the code is:

require 'jabber4r/jabber4r'
require 'jabber4r/rexml_1.8_patch'

begin
  session = Jabber::Session.bind('bob at jabber/Ruby', 'passwd', 5222, true)
  msg = session.new_message('neilmcl at jabber')
  msg.set_subject('test message')
  msg.set_body('test transmission')
  msg.send
rescue Exception => error
  puts error
ensure
  session.release if session
end


Thanks again,
Regards,
Neil.

Using Non-SASL digest auth (the method used by jabber4r in your XML) you
need to specify a resource for the user at the time of login.  I don't
know how to do that as I've never used that library.  Notice the empty
<resource/> element in the iq set you sent for authentication.  That is
not allowed.  See the JEP fo Non-SASL Authentication for more details.
