Subject Re: Remote connection issues with 5.3.0
Date Thu, 18 Feb 2010 19:40:32 GMT

Oops, found the answer with just a little more checking.

I compared my activemq.xml to the new example ones and noticed a change to
the <transportConnectors> from 'uri="tcp://localhost:61616"' to
'uri="tcp://0.0.0.0:61616"'.   Made the change in my config and, I'm back up
and running.
