Class ResourceManagerFactory

java.lang.Object
  org.jboss.jms.tx.ResourceManagerFactory

public class ResourceManagerFactory

extends java.lang.Object

This class manages instances of ResourceManager. It ensures there is one instance per instance of JMS server as specified by the server id. This allows different JMS connections to the same JMS server (the underlying resource is the JMS server) to use the same resource manager. This means isSameRM() on XAResource returns true, allowing the Transaction manager to join work in one tx to another thus allowing 1PC optimization which should help performance.
