I am trying to get my first JMS project working using the Sun reference version of j2ee connection to Tibco EMS.  I figured out how to get two Windows machines running j2ee to talk to each other, but talking to Tibco on a UNIX box isn't working.  I'm new to j2ee and JMS, so I really don't know where to go from here.  I realize I haven't given much information here, but I don't know what is needed to diagnose this.  Can anyone give me guidance on what I should do next?

Thanks very much.
