Hello all, I'm trying to configure my MDB's to run in an HA environment. I have half of the MDB working. The mdb performs the following tasks 1. Read from HA JBoss MQ Queue 2. Process message 3. Push the message onto a different queue. I'm using 2 identical nodes (vmware instances, prodjboss1, and prodjboss2), and I have edited the file 'deploy/jms/hajndi-jms-ds.xml' to have the following prodjboss1 | java.naming.provider.url=${jboss.bind.address:localhost}:1100,prodjboss2:1100 | prodjboss2 | java.naming.provider.url=${jboss.bind.address:localhost}:1100,prodjboss1:1100 | Both my MDB's read from the correct master node. However, I'm trying to connect to a different output queue via my MDB, and I'm not getting the expected behavior. I'm using the following JNDI properties on both nodes when attempting to connect to the output queue | java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory | java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces | java.naming.provider.url=jnp://prodjboss1:1100,prodjboss1:1100 | The lookup always works correctly on the node that's the master node, but fails on all slave nodes. Am I missing another property that I need to add in order to get automatic master discovery working and get all slaves connecting to the master MQ node to push data onto the queue?
