Package org.ow2.joram.jakarta.jms

Class MultiSessionConsumer

java.lang.Object

org.ow2.joram.jakarta.jms.MessageConsumerListener

org.ow2.joram.jakarta.jms.MultiSessionConsumer

All Implemented Interfaces:

jakarta.jms.ConnectionConsumer, ReplyListener

public final class MultiSessionConsumer
extends MessageConsumerListener
implements jakarta.jms.ConnectionConsumer

The MultiSessionConsumer is threaded (see MessageDispatcher) because the session pool can hang if there is no more available ServerSession.
