This graphical example illustrates key concepts of the JMS publish/subscribe model. Run the example to observe the behavior of transacted sessions, persistent messages, and durable subscribers.
The following sections describe how to:
$ javac -d %CLIENT_CLASSES% JMSDrawDemo.java
The following items have been preconfigured and/or predefined for your convenience:
Note: If you have configured the server to run the examples.jms.topic example, then no additional configuration changes are required to run the JMSDrawDemo example, and you can skip to the section Run the Example.
To configure the server:
$ java examples.jms.drawdemo.JMSDrawDemo t3://hostname:port [DurableSubID]where:
The JMSDrawDemo application displays a command panel at the bottom of the screen allowing you to:
Check the Persistent checkbox to enable persistent messaging. Persistent messages are of most interest to durable subscribers. You can establish a durable subscription by specifying the (optional) durable subscriber ID as the second argument on the command line. Check the Persistent checkbox to enable persistent JMS messages. Persistent messages sent when the subscriber is not active will be delivered when the subscriber reattaches, even after a WebLogic Server reboot.
Check the Transacted checkbox to turn on transacted mode. When the transacted mode is on, JMS does not send messages until you click the Commit button to commit the transaction, or click the Rollback button to roll back the transaction. To view a transaction commit operation, click several times on one canvas, then click the Commit button. The other canvasses are updated only after you select Commit.
Click the Clear button to send a clearScreen message to the topic. When the message is delivered, all instances of the application clear their canvasses.
Click the Quit button to quit the application.
