JMS Step 1 - How to Create a Simple JMS Queue in Weblogic Server 11g

JMS Step 1 - How to Create a Simple JMS Queue in Weblogic Server 11g

This example shows the steps to create a simple JMS queue in WebLogic Server 11g for testing purposes. For example, to use with the two sample programs QueueSend.java and QueueReceive.java which will be shown in later examples.

Additional, detailed information on JMS can be found in the following Oracle documentation:

Oracle® Fusion Middleware Configuring and Managing JMS for Oracle WebLogic Server
11g Release 1 (10.3.6)
Part Number E13738-06
http://docs.oracle.com/cd/E23943_01/web.1111/e13738/toc.htm

1. Introduction and Definitions

A JMS queue in Weblogic Server is associated with a number of additional resources:

JMS Server

A JMS server acts as a management container for resources within JMS modules. Some of its responsibilities include the maintenance of persistence and state of messages and subscribers. A JMS server is required in order to create a JMS module.

JMS Module

A JMS module is a definition which contains JMS resources such as queues and topics. A JMS module is required in order to create a JMS queue.

Subdeployment

JMS modules are targeted to one or more WLS instances or a cluster. Resources within a JMS module, such as queues and topics are also targeted to a JMS server or WLS server instances. A subdeployment is a grouping of targets. It is also known as advanced targeting.

Connection Factory

A connection factory is a resource that enables JMS clients to create connections to JMS destinations.

JMS Queue

A JMS queue (as opposed to a JMS topic) is a point-to-point destination type. A message is written to a specific queue or received from a specific queue.

The objects used in this example are:

Object Name

Type

JNDI Name

TestJMSServer

JMS Server

TestJMSModule

JMS Module

TestSubDeployment

Subdeployment

TestConnectionFactory

Connection Factory

jms/TestConnectionFactory

TestJMSQueue

JMS Queue

jms/TestJMSQueue

2. Configuration Steps

The following steps are done in the WebLogic Server Console, beginning with the left-hand navigation menu.

2.1 Create a JMS Server

  1. Services > Messaging > JMS Servers

  2. Select New
  3. Name: TestJMSServer
    Persistent Store: (none)
  4. Target: soa_server1  (or choose an available server)
  5. Finish

The JMS server should now be visible in the list with Health OK.

2.2 Create a JMS Module

  1. Services > Messaging > JMS Modules
  2. Select New
  3. Name: TestJMSModule
    Leave the other options empty
  4. Targets: soa_server1  (or choose the same one as the JMS server)
    Press
    Next
  5. Leave “Would you like to add resources to this JMS system module” unchecked and  press Finish .

2.3 Create a SubDeployment

A subdeployment is not necessary for the JMS queue to work, but it allows you to easily target subcomponents of the JMS module to a single target or group of targets. We will use the subdeployment in this example to target the following connection factory and JMS queue to the JMS server we created earlier.

  1. Services > Messaging > JMS Modules
  2. Select TestJMSModule
  3. Select the Subdeployments  tab and New
  4. Subdeployment Name: TestSubdeployment
  5. Press Next
  6. Here you can select the target(s) for the subdeployment. You can choose either Servers (i.e. WebLogic managed servers, such as the soa_server1) or JMS Servers such as the JMS Server created earlier. As the purpose of our subdeployment in this example is to target a specific JMS server, we will choose the JMS Server option.
    Select the
    TestJMSServer created earlier
  7. Press Finish

2.4  Create a Connection Factory

  1. Services > Messaging > JMS Modules
  2. Select TestJMSModule  and press New
  3. Select Connection Factory  and Next
  4. Name: TestConnectionFactory
    JNDI Name:
    jms/TestConnectionFactory
    Leave the other values at default
  5. On the Targets page, select the Advanced Targeting  button and select TestSubdeployment
  6. Press Finish

The connection factory should be listed on the following page with TestSubdeployment and TestJMSServer as the target.

2.5 Create a JMS Queue

  1. Services > Messaging > JMS Modules
  2. Select TestJMSModule  and press New
  3. Select Queue and Next
  4. Name: TestJMSQueue
    JNDI Name: jms/TestJMSQueue
    Template: None
    Press
    Next
  5. Subdeployments: TestSubdeployment
  6. Finish

The TestJMSQueue should be listed on the following page with TestSubdeployment and TestJMSServer.

Confirm the resources for the TestJMSModule. Using the Domain Structure tree, navigate to soa_domain > Services > Messaging > JMS Modules then select TestJMSModule

You should see the following resources

The JMS queue is now complete and can be accessed using the JNDI names

jms/TestConnectionFactory and
j
ms/TestJMSQueue.

In the following blog post in this series, I will show you how to write a message to this queue, using the WebLogic sample Java program QueueSend.java.
