I had to switch to JBoss MQ provider instead of JBoss Messaging (JBossMessaging_1_4_0_SP3_CP03). The reason is bug in JBoss Messaging. I was unable to send messages IN ONE TRANSACTION to services that are deployed in cluster of esb servers. I am going to announce the bug to JBoss Messaging. But I am in hurry now to localize the bug in JBoss Messaging, create testcase.....
BTW.... I had to switch all my services to XAConnectionFactory (I could configure JBoss MQ as well) so that I could send message to esb service in transaction.
If there's a bug then make sure to create a JIRA in JBM and can you bounce a link into this forum too? Thanks.
