JBM 1.4.4 dynamic port/firewall issue

belcar Sep 29, 2009 6:04 AM

Hi All

I'm trying to access a JBM 1.4.4. environment deployed on JBoss 4.2.3 from a remote JBoss 4.2.3 server (client). The messaging client server is behind a firewall.

We've opened following ports on the firewall: 1099, 1098, 4444 and 4457.
Apparently we needed to open an additional undocumented port (55794) in order to let the client code create the JMS connection and ask for a JMS Session.

However, for some reason the client code that tries to open a JMS connection seems to use dynamic ports. Some time later on (after some restarts) the client tries to access port 17661 on the JBM machine (instead of 55794). This leads to a process freeze.

Is there a configuration option so we can fix this port and/or can somebody please explain what is going on?

Thanks in advance for your reply.

Did you configure the secondaryBindPort and secondaryConnectPort in your remoting configuration file?

I simply followed the installation documents and they didn't mention this. A quick lookup points me to the deploy/jboss-messaging.sar/remoting-bisocket-service.xml on my JBM server.

As a best practice, do I need to enable both the bindPort and the ConnectPort?

Thx in advance

Sure, you should use them together. Please note their values have to be same.

Thank you for your quick reply! I'll test it immediately.
Do you know if there exist documentation about these ports?

Thank you

Hi

I've verified and it works like a charm. I now receive a NullPointerException on the createSession() function now, but I'll research and possibly open another thread for it.

Tx a lot
