Life Cycle Listener

You could have some custom initialization and cleanup when an application, a session, a desktop or an execution is instantiated or about to being destroyed.

There are two steps:

1. Implements the corresponding interface. For example, WebAppInit for application's initialization
2. Register it in WEB-INF/zk.xml, or in Java.

Application	Init: WebAppInit Cleanup: WebAppCleanup

The registration in WEB-INF/zk.xml is the same, no matter what interface you implement:

<listener>
    <listener-class>my.MyImplementation</listener-class>
</listener>

The registration in Java is done by Configuration.addListener(Class).

webapp.getConfiguration().addListener(my.MyImplementation.class);
