To provide messaging support on a WebSphere® Application Server Version 5 node, there is at most one JMS server and some number of JMS resources configured for the default messaging JMS provider on that node.
A JMS server on a Version 5 node serves the JMS resources (connection factories and destinations) for that node. The JMS server is managed as a separate process to application servers on the same node. Any application server within the domain can access JMS resources served by any JMS server on any node in the domain.
A connection factory encapsulates the configuration properties used to create connections with the JMS provider, to enable applications to access JMS destinations.
The main components of JMS support on a Version 5 node are shown in the figure The main JMS components on a version 5 node.
