Re: ConnectionFactory.createConnection returns null

Hi,

I've struggled a bit with similar problems. First off I'd say make
sure your program is reading your jndi.properties file correctly
(maybe it's not in your class path?) or maybe it is not setup right?
using the standard tcp, also noticed that the OpenJMS server must
listen on both TCP and RMI ports for it to actually work. I once
turned off the RMI listener and nothing worked.
