Sending and Getting JMS Messages

A process can send JMS messages and get JMS messages from a queue in a loop.

Before you begin

TIBCO Enterprise Message Service must be running.

    Procedure
  1. In the samples directory, select palette > jms > GetQueueMessage and double-click tibco.bw.sample.palette.jms.GetQueueMessage. For more information, see Accessing Samples.
  2. In the Project Explorer view, expand the tibco.bw.sample.palette.jms.GetQueueMessage project.
  3. Verify your TIBCO Enterprise Message Service connection.
    1. Fully expand the Resources directory.
    2. Double-click JMSConnectionResource.jmsConnResource.
    3. In the Basic Configuration dialog, click the Test Connection button to verify the connection.
  4. Fully expand the Processes directory and double-click GetQueueMessage.bwp.
  5. Click Run > Debug Configurations.
  6. At the left hand tree of Debug Configuration wizard, expand BusinessWorks Application and select BWApplication.
  7. Click the Applications tab and then click the Deselect All button if you have multiple applications. Select the checkbox next to tibco.bw.sample.palette.jms.GetQueueMessage.application.
  8. Click Debug.
    This runs the sample in Debug mode.
  9. Click the Terminate icon to stop the process.

Understanding the Configuration

The JMS Send Message activity sends the messages with the message style set to Queue.

The Get JMS Queue Message activity receives the JMS messages from a Queue in a loop. The activity is placed in a group and the group action is set to Repeat.

The condition loops five times and receives five messages.
