[openjms-user] problems getting OpenJMS to connect over tcp (from Jahia CMS)

[Chris S. <Chr...@Ne...>]

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=3D9099205).

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              =3D   =
rmi\://blah.com.au\:1099/

to read:

org.jahia.cache.jmsCacheContextProviderURL              =3D   =
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                       =3D   true
org.jahia.cache.jmsCacheInitialContextFactory           =3D   =
org.exolab.jms.jndi.InitialContextFactory
org.jahia.cache.jmsCacheContextProviderURL              =3D   =
rmi\://careerone01.ac3.com.au\:1099/
org.jahia.cache.jmsCacheTopicConnectionFactoryName      =3D   =
JmsTopicConnectionFactory
org.jahia.cache.jmsCacheTopicName                       =3D   jahiaCache
org.jahia.cache.jmsCacheMaxMessagesInPackage            =3D   2000
org.jahia.cache.jmsServerLookupSleepTime                =3D   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=3Djavax.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
