Creating Simple Weblogic JMS Queues

In this post, we'll be seeing how to create a simple JMS queue in Weblogic application server. Based on the queues created in this tutorial, new tutorials will be posted in the future on how to listen and send message to a JMS queue.

1.  Steps to create a JMS Server

• Open Weblogic console
• Click Services -> Messaging -> JMS Servers
• Click “NEW” button to create a new JMS server like below
  
• The Name of the server should be “TestJMSServer”. Click “NEXT”
• Select the appropriate target in production like below and Click “FINISH”.

2.  Steps to create JMS module

• Click Services -> Messaging -> JMS Modules
• Click “NEW” button to create a new JMS Module like below

• The Name of the server should be “TestJMSModule”. Click “NEXT”
• Select the appropriate target in production like below.

• Leave the “Would you like to add resources to this JMS system module?” unchecked and click FINISH.

2.1    Create JMS sub-deployments

• Click on the recently created JMS module “TestJMSModule” and select the “Subdeployments” tab.
• Click “NEW” button to create a new sub-deployment like below.
• Put the sub-deployment name as “TestQueues” and click “NEXT”
  
• Select the recently created JMS server “TestJMSServer” as target and click Finish

4.  Create JMS Queues and Connection Factory

4.1    Create Connection Factory

• Click Services -> Messaging -> JMS Modules
• Click on the recently created JMS module “TestJMSModule” and click “NEW” button.
• Select “Connection Factory” option like below

• Specify the name and JNDI Name as “TestConnectionFactory” like below

• Select the default option for target and click “FINISH”.

4.2    Create Queue

• Click Services -> Messaging -> JMS Modules
• Click on the recently created JMS module “TestJMSModule” and click “NEW” button.
• Select “Queue” option like below

• Set the name and JNDI name as “TestQueue” like below

• Select the recently created “TestQueues” sub-deployment and “TestJMSServer” as target for the queues like below. Click “Finish” at the end.

Setting Session Timeout (J2EE)

There are two ways of setting session timeout in Java. One is by utilizing the deployment descriptor and the other is by calling setMaxInactiveInterval() under HttpSession interface.

Using Deployment Descriptor:



Setting time-out at the deployment descriptor gives impact to the whole web-application. Looking at the example above, the session for the whole web application will terminate in 5 minutes (note: In deployment descriptor the time used for the timeout is measured in minutes)


Using setMaxInactiveInternal() :

HttpSession session = request.getSession() ;
session.setMaxInactiveInterval( 5 * 60) ;

The difference between using setMaxInactiveInterval() in a program and using in deployment descriptor are:

• setMaxInactiveInterval() method will only cause session time-out for a particular session instance and not the whole web-application.
• Other than that in setMaxInactiveInterval() method, time is measured in seconds not minutes. Take a look at the code above, to reach 5 minutes expiry (5*60) is used.
