The following sample demonstrates creating a messaging engine (using the JMSServer-1.0 feature), the MDB feature (mdb-3.1), and the JMS Client feature (JMSMessaging-1.1).

Description

The JMS sample contains a server definition which includes the features for creating the messaging engine (wasJmsServer-1.0), MDB feature (jmsMdb-3.1), JMS Client feature (wasJmsClient-1.1). It also contains a very simple JMS application, JMSSample.war, which contains couple of servlet for performing Point to Point and Publish/Subscribe messaging.The JMS Servlet provides means to send/receive messages to a queue and also publish and subscribe messages from a Topic. For each of the function, servlet logs the appropriate logs into the console.log.

This sample can be installed onto runtime versions 8.5.5.0 and later.

Instructions

To run the JMSApp application:

  1. Extract the sample into the Liberty installation by running the command below from the root of your server installation:
    java -jar JMSSampleServer.jar
  2. Start the JMSSampleServer server by running the command below from the bin directory in the Liberty profile installation:
    server run JMSSampleServer
  3. Confirm the application started by looking for the following message in the log:
    CWWKZ0001I: Application JMSApp started in XX.XX seconds.
  4. In your browser, enter the URL for the application (see notes for other actions):
    For Point to Point (P2P) - http://localhost:9124/JMSApp/JMSSampleP2P?ACTION=SendMessage 
    For Publish Subscribe (Pub/Sub) - http://localhost:9124/JMSApp/JMSSamplePubSub?ACTION=NonDurableSubscriber 

    (where 9124 is the HTTP endpoint on which the JMSSample servlet is running).

  5. Once you run the above link you should see a completion message on the Web browser.
