Prerequisites

• Ensure you have administrative access to the IBM WebSphere Application Server (WAS) Integrated Solutions Console (admin console).
• The server should be running, and you need to decide on the scope (e.g., cell, node, server) for the resources.
• This guide focuses on the Default Messaging Provider (using Service Integration Bus or SIBus), which is the built-in JMS provider in WAS. If using WebSphere MQ, additional configuration for the MQ provider is required.
• Restart the server after major changes if prompted.

Step 1: Create a Service Integration Bus

The service integration bus acts as the messaging backbone for JMS resources.

1. Log in to the WebSphere Integrated Solutions Console.
2. Navigate to Service integration > Buses.
3. Click New.
4. Enter a unique bus name (e.g., MyJMSBus).
5. Clear the Bus security option unless required.
6. Click Next, then Finish to create the bus.

Step 2: Add the Server as a Bus Member

This enables the server to host messaging engines on the bus.

1. Select the bus you created (e.g., MyJMSBus).
2. Under Additional properties, click Bus members.
3. Click Add.
4. In the Add a New Bus Member wizard:
   • Select Messaging engine as the bus member type.
   • Choose your server (e.g., server1) from the list.
   • For the message store, select File store (default for non-clustered) or Data store for database persistence, and configure properties if needed.
5. Click Next, then Finish.
6. Restart the WebSphere Application Server to activate the bus member.

Step 3: Create a JMS Connection Factory

A connection factory is required to connect JMS clients to the provider.

1. Navigate to Resources > JMS > Connection factories.
2. Select the appropriate scope (e.g., Server scope for server1) and click New.
3. Select Default messaging provider and click OK.
4. Enter details:
   • Name: e.g., MyJMSConnectionFactory.
   • JNDI name: e.g., jms/MyConnectionFactory.
   • Bus name: Select MyJMSBus from the drop-down.
   • Leave other defaults (e.g., Provider endpoints as auto-detected).
5. Click Apply, then Save to the master configuration.

Step 4: Create a JMS Queue

This defines the queue destination for point-to-point messaging.

1. Navigate to Resources > JMS > Queues.
2. Select the appropriate scope and click New.
3. Select Default messaging provider and click OK.
4. Enter details:
   • Name: e.g., MyJMSQueue.
   • JNDI name: e.g., jms/MyQueue.
   • Bus name: Select MyJMSBus.
   • Queue name: Select Create Service Integration Bus Destination, enter a unique identifier (e.g., MyQueueDestination), and select the bus member created earlier.
   • Base queue name: e.g., $MyJMSBus:MyQueueDestination (auto-generated).
5. Configure additional properties if needed (e.g., delivery mode, expiry).
6. Click Apply, then Save to the master configuration.

Step 5: (Optional) Create Activation Specifications for Message-Driven Beans (MDBs)

If using MDBs to consume from the queue, configure activation specs.

1. Navigate to Resources > JMS > Activation specifications.
2. Select the appropriate scope and click New.
3. Select Default messaging provider and click OK.
4. Enter details:
   • Name: e.g., MyActivationSpec.
   • JNDI name: e.g., jms/activation/MyActivationSpec.
   • Bus name: Select MyJMSBus.
   • Destination type: Queue.
   • Destination: Enter the JNDI name of the queue (e.g., jms/MyQueue).
5. Click Apply, then Save to the master configuration.

Verification and Testing

• After saving, sync nodes if in a clustered environment.
• Restart the server.
• Use a JMS client application to test sending/receiving messages via the JNDI names.
• Monitor via Service integration > Buses > [Your Bus] > Bus members > [Your Member] > Messaging engines.

For advanced configurations (e.g., security, clustering), refer to IBM documentation.
