The code below is working with the xmpp4r form
http://home.gna.o...

require 'XMPP4R'
begin
# Connect to the server and set presence to available for chat.
jid = Jabber::JID.new('myjid@xmppserver/Resource')
client = Jabber::Client.new(jid, false)
client.connect
client.auth('passwd')
client.send(Jabber::Presence.new.set_show(:chat).set_status('Ruby!'))

# Send an Instant Message.
body = 'Hi XMPP'
to_jid = Jabber::JID.new('tojid@xmppserver')
message = Jabber::Message::new(to_jid,
body).set_type(:normal).set_id('1')
client.send(message)
end

question:

how do I receive messages, since I can only send?

Try looking at some of the examples. If you installed the gem, then go to:
.../gems/xmpp4r-0.3.2/data/doc/xmpp4r/examples/

And, look for add_message_callback in the RDoc:
http://home.gna.o...rdoc/
http://home.gna.o...rdoc/classes/Jabber/Stream.html#M000487

examples/basic/echo_threaded.rb:
cl = Client::new(myJID)
cl.connect
...
cl.add_message_callback do |m|
if m.type != :error
puts m.body
end
end

Something like that, i believe.

client.add_message_callback do |m|
print "#{m.from} - #{m.body}\n"
end

Thanks for your help.

I googled out on xmppr4-simple. It appears to easier and working well.
Here is the code that runs well with ejabberd sever:

require 'rubygems'
require 'xmpp4r-simple'
im = Jabber::Simple.new('zo@myejabberd','zo')

im.deliver('gm@myejabberd','hello xmpp')

puts 'send done'
sleep(3)

im.received_messages { |msg| puts "#{msg.body} #{msg.type}" }

im.disconnect

Hi Zablon,

I can send IM to only by setting presence status, But my account have
more than 50 or 100 contacts. It will take long time to set the presence
and getting status message from each contact.

ie,
client.send(Jabber::Presence.new.set_show(:chat).set_status('Ruby!'))
line of code breaks the functionality of client.send(message).

Setting presence took long time, but before to that send message code
executed. If I have to wait for getting result of setting presence and
then running the send message code only results the required output.

Is there any way to send IM without setting Presence.

My sever installed with Openfire and IM gateway plugin. Whether I have
to install any other plugin or source to automatically log into
Transport.

Please give your valuable suggestion.

Regards,
T.Veeraa.

Veera,
I was only trying out on this code. I didnt go much deep.

I was trying to find a way of communicating between my software modules.
I decided to use ISO 8583 protocol instead.

Sorry, I wish I could help.
