    <p>I have MQ as an external JMS server on my Weblogic server. The thing is that I need to rollback the message and retry until backout threshold is reached. Then I need to move the message to backout queue.</p> <p>The MessageDrivenContext.setRollbackOnly() method takes care of that just fine. The problem, however, is with the message on the backout queue - it is uncommited.</p> <p>Moreover, the messages are being taken from backout queue and processed again as soon as new message appears on the main queue.</p> <p>This suggest me that there is something teribly wrong with my approach. I cannot, however, change the fact, that I have to retry the onMessage() with the same message a couple of times and send it to backout queue is backout threshold was reached.</p> <pre><code>@MessageDriven( name="MQListener", mappedName = "jms.mq.SOME.QUEUE.NAME", activationConfig = { @ActivationConfigProperty(propertyName = "destinationType",propertyValue = "javax.jms.Queue"), @ActivationConfigProperty(propertyName = "destination", propertyValue = "jms.mq.SOME.QUEUE.NAME"), @ActivationConfigProperty(propertyName = "connectionFactoryJndiName", propertyValue = "jms.mq.MQ"), @ActivationConfigProperty(propertyName = "useJNDI", propertyValue = "true") }) public class MQListener implements MessageListener { @Resource private MessageDrivenContext context; @Override public void onMessage(Message message) { String messageContent=""; try { messageId = message.getJMSMessageID(); if (message != null) { messageContent = ((TextMessage)message).getText(); if(!doSomething(messageContent)){ // doSomething fails, I need to rollback the message and try again: context.setRollbackOnly(); } } } catch (Exception e) { throw new RuntimeException(); } } private boolean doSomething(String messageContent){ // ... } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
