    <p><a href="http://static.springsource.org/spring/docs/2.5.x/reference/beans.html#context-functionality-events"><strong>Spring has some standard events which you can handle.</strong></a> </p> <p>To do that, you must create and register a bean that implements the <code>ApplicationListener</code> interface, something like this:</p> <pre><code>package test.pack.age; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationEvent; import org.springframework.context.ApplicationListener; import org.springframework.context.event.ContextRefreshedEvent; public class ApplicationListenerBean implements ApplicationListener { @Override public void onApplicationEvent(ApplicationEvent event) { if (event instanceof ContextRefreshedEvent) { ApplicationContext applicationContext = ((ContextRefreshedEvent) event).getApplicationContext(); // now you can do applicationContext.getBean(...) // ... } } } </code></pre> <p>You then register this bean within your <code>servlet.xml</code> or <code>applicationContext.xml</code> file:</p> <pre><code>&lt;bean id="eventListenerBean" class="test.pack.age.ApplicationListenerBean" /&gt; </code></pre> <p>and Spring will notify it when the application context is initialized.</p> <p>In Spring 3 (if you are using this version), the <a href="http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/context/ApplicationListener.html"><code>ApplicationListener</code> class is generic</a> and you can declare the event type that you are interested in, and the event will be filtered accordingly. You can simplify a bit your bean code like this:</p> <pre><code>public class ApplicationListenerBean implements ApplicationListener&lt;ContextRefreshedEvent&gt; { @Override public void onApplicationEvent(ContextRefreshedEvent event) { ApplicationContext applicationContext = event.getApplicationContext(); // now you can do applicationContext.getBean(...) // ... } } </code></pre>

    1. COok, thanks . it's good to know that spring3 filters the events. I did notice the applicationlistener class before. but its hooks would also be called for RequestHandledEvent.

    2. COAny idea what will happen if you use the annotation stuff and you declare two classes ? Non-annotation ( XML ) and two ? Will they fire in the order declared? thanks ;)

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.
