JMS Palette

Java Message Service (JMS) is a specification about sending and receiving messages between two or more applications in a Java environment. The JMS palette is used to send and receive JMS messages in a process.

The models supported are:

  • Point-to-Point (queues): Message delivered to one recipient
  • Publish/Subscribe (topics): Message delivered to multiple recipients

JMS supports these two models by using distinct interfaces within the API for each messaging model.

For more information about JMS and its message models, see the documentation of the JMS provider or JMS specifications.

  • Common JMS Properties and Headers
    JMS properties comprise message headers and message properties. MessageHeader properties are set by the JMS client sending the message. You can view these after the message is received. You can also set MessageProperties on the outgoing messages on the Input tab of the activity that sends messages.
  • Get JMS Queue Message
    Get JMS Queue Message is an asynchronous activity that retrieves a message from the specified queue. You can use this activity to perform a receive operation on the queue as opposed to waiting for a queue message to be delivered to the Wait for JMS Queue Message activity.
  • JMS Receive Message
    JMS Receive Message is a process starter activity that starts the process based on the receipt of a message for the specified JMS destination.
  • JMS Request Reply
    JMS Request Reply is an asynchronous activity that is used to send a request to a JMS destination and wait for a response from the JMS client.
  • JMS Send Message
    JMS Send Message is a synchronous activity that sends a message to the specified JMS destination.
  • Reply to JMS Message
    Reply To JMS Message is a synchronous activity that sends a reply to a previously received JMS queue or topic message. The Reply For Event field in the General tab lists the activities that can receive the JMS message. The activity you select determines the response of the reply message.
  • Wait for JMS Request
    Wait for JMS Request is a signal-in activity that waits for the receipt of a message for the specified JMS destination.
