Hmmm, yes it seems as if this has nothing to do with the brokername? Even though i find it strange that it is never set (i guess you can see this from the log also: default.ActiveMQ-4.alive.%null%tcp://artimus:16161)
I have completly removed my firewall so that im certain that nothing is blocking datagram packet. I wonder, has this something to do with that i run broker and client on the same machine?
