MessageListenerFactory.java

 

In this sample, a message listener factory object is associated with each ServerSessionPool instance. The MessageListenerFactory class represents a very simple interface that is used to obtain an instance of a class that implements the javax.jms.MessageListener interface. The class contains a single method:

 javax.jms.MessageListener createMessageListener();

An implementation of this interface is supplied when the ServerSessionPool is constructed. This object is used to create message listeners for the individual JMS sessions that back up the ServerSessions in the pool. This architecture means that each separate implementation of the MessageListenerFactory interface must have its own ServerSessionPool.

WebSphere MQ JMS includes a sample MessageListenerFactory implementation, which is discussed in CountingMessageListenerFactory.java.
