Sorry I have taken so long to look at this. Before I investigate any deeper, there is one obvious thing I can see wrong in your remote jms provider config: | <!-- The combined connection factory --> | <attribute name="FactoryRef">java:/XAConnectionFactory</attribute> | <!-- The queue connection factory --> | <attribute name="QueueFactoryRef">java:/XAConnectionFactory</attribute> | <!-- The topic factory --> | <attribute name="TopicFactoryRef">java:/XAConnectionFactory</attribute> | <!-- Uncomment to use HAJNDI to access JMS --> | You are doing your lookups with the "java:" prefix. As I'm sure you know, in JNDI, anything that starts with "java:" represents a lookup in the same VM. You need to lookup in the global JNDI space, i.e. "/XAConnectionFactory" rather than "java:/XAConnectionfactory". Take a look at http://www.jboss.org/wiki/Wiki.jsp?page=HowDoIConfigureAnMDBToTalkToARemo... for how to set up a remote JMS provider. Can you report back after trying this and we can investigate further if a problem still exists? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4073957#...
