Thanks to the advices i found on this forum, i managed to get two Jboss servers (under windows) send messages (using queues) one to the other.
Now, I'm migrating the server managing the queues to linux. So I copied the whole jboss directory to linux (fedora) and started the two servers (one on linux and one on windows).
As i get no problem from my previous conf, i guess it should work. But i'm getting this error :
11:20:49,406 ERROR [DLQHandler] Initialization failed DLQHandler javax.jms.JMSException: Error creating the dlq connection: null
i get it!
In the /etc/hosts file, i put this
127.0.0.1 localhost 127.0.0.1 fedora (the name of the server)
127.0.0.1 localhost xx.xx.xx.xx fedora (with the real ip address)
