    <p>I'm not sure I get what you're trying to do. If you're trying to have multiple messages processed concurrently, get away from the JmsTemplate and use a <a href="http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/jms/listener/DefaultMessageListenerContainer.html" rel="nofollow">DefaultMessageListenerContainer</a> with <a href="http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/jms/listener/DefaultMessageListenerContainer.html#setConcurrentConsumers%28int%29" rel="nofollow">concurrentConsumers</a>. Also available via the <a href="http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/jms.html#jms-namespace" rel="nofollow">JMS namespace</a>.</p> <p>For example, it seems that you could throw away all the code that you're showing in your question and use this instead:</p> <pre><code>&lt;jms:listener-container concurrency="10"&gt; &lt;jms:listener destination="some.queue" ref="fooService" method="handleNewFoo"/&gt; &lt;/jms:listener-container&gt; </code></pre> <p>That will automatically spawn up to 10 threads for concurrent message processing. When a message comes in, it will use one of the worker threads to call fooService.handleNewFoo(), where fooService is a bean in your Spring context.</p> <p><strong>Edit:</strong> I've created a sample project on github showing a basic Spring JMS setup. You can browse the source at <a href="https://github.com/zzantozz/testbed/tree/master/basic-spring-jms" rel="nofollow">https://github.com/zzantozz/testbed/tree/master/basic-spring-jms</a> or just clone and run it:</p> <pre><code>git clone git://github.com/zzantozz/testbed.git tmp cd tmp mvn compile exec:java -Dexec.mainClass=rds.jms.Main -pl basic-spring-jms </code></pre> <p>There's a main class that starts a JMS broker and starts Spring. When Spring starts, it inits a bean that begins sending JMS messages. There's also a Spring message listener as I described above that consumes messages and passes them to the same bean that produces messages, which prints them to stdout.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
