Answer / Simpal Chauhan
To use Sorted Queues in WebLogic Server, you can follow these steps:
1. Declare a JMS queue with the `XA` and `SORTED` options enabled. For example:
- `<resource-ref>
<res-ref-name>myqueue</res-ref-name>
<res-type>javax.jms.Queue</res-type>
<res-auth>Container</res-auth>
<jndi-name>java:comp/env/myqueue</jndi-name>
</resource-ref>`
2. Send messages with the sort key specified. For example, in Java:
- `QueueSession session = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = (Queue) context.lookup("java:comp/env/myqueue");
TextMessage message = session.createTextMessage("This is a sorted message with sort key 10");
message.setJMSProperty("JMSXGroupID", "some-group");
message.setJMSPriority(DeliveryConstants.DEFAULT_PRIORITY);
message.setJMSMessageID(UUID.randomUUID().toString());
message.setStringProperty("JMSXSortedKey", "10");
sender.send(queue, message);`
