JMS triggers

1) A JMS trigger is a trigger that receives messages from a destination (queue or topic) on a JMS provider and then processes those messages.

2) A JMS message is a Broker document; its document type is related to that of the topic or queue being published.

3) The webMethods Broker implementation of JMS supports the JMS publish-subscribe (pubsub) and point-to-point (PTP) messaging models.

4) Pub-Sub Messaging

In pub-sub messaging, message producers publish messages, and message subscribers consume those messages. If multiple message consumers subscribe to the same topic, each consumer will be given a copy of the message.

5) Point-to-Point Messaging

In JMS PTP messaging, a message producer sends messages to a message queue, and a message consumer retrieves messages from that queue. A JMS message queue is implemented as a guaranteed Broker client with the same name.

6)Durable Subscribers

The JMS pub-sub model supports durable subscribers. A durable subscriber's subscription remains valid until explicitly removed by the client program; thus, a durable subscriber survives both client connection failures and server restarts.
