JMS Modules are application-related definitions that are independant of the domain environment. AquaLogic BPM requires you to create a JMS system module that is targeted to each managed server within a cluster.
JMS System modules are created at the container level as opposed to the applications level. System modules are used to configure JMS resources including queues and topic connections factories. System modules are configured as subdeployments to allow them to be targeted to multiple managed servers.
The new JMS system module appear in the list of JMS modules. You can now create the required JMS resources.
