JMS clients can operate with both publish/subscribe and point-to-point messages. The publish/subscribe and point-to-point application communication models use virtual channels called destinations. In the publish/subscribe model, the destinations are topics. For the point-to-point model, the destinations are known as queues.
Property | Description |
Connection Factory Name | A string name that is passed to JNDI to look up the
administered connection factory object. The connection factory object is used
to create a connection to the JMS destination.
|
Subscription Topic | The string name that is passed to JNDI to look up the JMS topic destination. The topic is used to create a JMS session when the node is being used to process publish/subscribe messages. |
Durable Subscription ID | This is a JMSInput node property only. It is a string
identifier that is specified if the node is to subscribe to a durable subscription
topic. A durable subscription is one that outlasts the client's connection to a message server. When a durable subscriber is disconnected from the server, it is the responsibility of the server to store messages that are published. Therefore, when the durable subscriber reconnects, the message server sends all the unexpired messages. Durable subscriptions cannot be unsubscribed from a message flow. It requires a separate administration task to unsubscribe a previously registered durable subscription. Some JMS providers supply an administration tool to perform this action. |
Source Queue | The string name that will be passed to JNDI to look up the JMS queue destination. The queue is used to create a JMS session when the node is being used to process point-to-point messages. |
The Subscription Topic and Source Queue properties are mutually exclusive because they configure the node to work with either the Publish/Subscribe message model or the Point-To-Point message model.
ADurable subscription ID is not valid without a Subscriber Topic property.
