    <p>I wouldn't bother with Quartz, it's overkill for something this simple. Java5 comes with its own scheduler, and it's good enough.</p> <p>Pre-Spring 3, this is was the easiest approach:</p> <pre><code>&lt;bean class="org.springframework.scheduling.concurrent.ScheduledExecutorFactoryBean"&gt; &lt;property name="scheduledExecutorTasks"&gt; &lt;list&gt; &lt;bean class="org.springframework.scheduling.concurrent.ScheduledExecutorTask"&gt; &lt;property name="period" value="30000"/&gt; &lt;property name="runnable"&gt; &lt;bean class="org.springframework.scheduling.support.MethodInvokingRunnable"&gt; &lt;property name="targetObject" ref="pitcher"/&gt; &lt;property name="targetMethod" value="voice"/&gt; &lt;/bean&gt; &lt;/property&gt; &lt;/bean&gt; &lt;/list&gt; &lt;/property&gt; &lt;/bean&gt; </code></pre> <p>With Spring 3, it can be ridiculously easy:</p> <pre><code>@Scheduled(fixedRate=30000) public void voice() { System.out.println(getShout()); } </code></pre> <p>and</p> <pre><code>&lt;beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd "&gt; &lt;bean id="pitcher" class="spring.com.practice.Pitcher"&gt; &lt;property name="shout" value="I started executing..."&gt;&lt;/property&gt; &lt;/bean&gt; &lt;task:annotation-driven/&gt; &lt;/beans&gt; </code></pre>

    2. CO@skaffman thank you for your response, I'll try that now, the thing is I want to do something more complicated so I want to start from bottom up. `I want to create 2 objects that send messages to each other, one to greet other to respond trough JMS messaging on JBOSS 5, and I want this done every 30 seconds.` So first thing to consider would be the executing task every 30 seconds and then onwards ..

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).
