problems getting OpenJMS to connect over tcp (from Jahia CMS)

Hi folks,

I am setting up a Jahia CMS (www.jahia.org) cluster according to the instructions in their Jahia Clustering HOWTO (v2) document. Jahia uses OpenJMS for syncing the CMS cache across multiple instances.

If I set up my two Jahia instances to use RMI to connect to OpenJMS (running on a third server) all is well - except that I cannot then firewall the machines properly because of the anonymous ports used (cf. http://sourceforge.net/mailarchive/message.php?msg_id=9099205).

So I switched across to the TCP connector by changing the Connector scheme to tcp. All apears fine and I can connect OK to OpenJMS with "telnet localhost 3030".

In Jahia, the config change is performed by just changing one line:

org.jahia.cache.jmsCacheContextProviderURL              =   rmi\://blah.com.au\:1099/

to read:

org.jahia.cache.jmsCacheContextProviderURL              =   tcp\://blah.com.au\:3030/

For completeness, this is the full extent of JMS configuration in Jahia's properties file:

### JMS Cache Settings ###############

org.jahia.cache.jmsCacheActivated                       =   true
org.jahia.cache.jmsCacheInitialContextFactory           =   org.exolab.jms.jndi.InitialContextFactory
org.jahia.cache.jmsCacheContextProviderURL              =   rmi\://careerone01.ac3.com.au\:1099/
org.jahia.cache.jmsCacheTopicConnectionFactoryName      =   JmsTopicConnectionFactory
org.jahia.cache.jmsCacheTopicName                       =   jahiaCache
org.jahia.cache.jmsCacheMaxMessagesInPackage            =   2000
org.jahia.cache.jmsServerLookupSleepTime                =   10000

I also opened up the appropriate ports: 3030 and 3035.

But this doesn't work and I get the following Jahia error in catalina.out:

1315607 [JMS Reconnection]  WARN - org.jahia.services.cache.JMSConnectionException: JMS Connection error, Could not get the InitialContext [org.exolab.jms.jndi.InitialContextFactory] on provider [tcp://blah.com.au:3030/]., root cause:Operation getNameParser failed: java.io.EOFException root cause=javax.naming.NamingException: Operation getNameParser failed: java.io.EOFException

I have since flushed my iptables so I know it is not a firewall problem.

Is this an OpenJMS config error on my part? Am I missing something?

Thanks in advance,

Chris
