The Servlet Container Model

You have created a Listener called AccountApplicationListener that receives events when the context of the web-application "account" is created or destroyed. How would you define this in your deployment descriptor?

1		`<listener>com.scwcd.AccountApplicationListener</listener>`
2		`<listener> <class>com.scwcd.AccountApplicationListener</class> </listener>`
3		`<listener> <listener-class>com.scwcd.AccountApplicationListener</listener-class> </listener>`
4		`<listener-class>com.scwcd.AccountApplicationListener</listener-class>`
5		`<web-app name="account"> <listener-class>com.scwcd.AccountApplicationListener</listener-class> </web-app>`

Explanation

Answer 3 is correct.

<listener>
  <listener-class>com.scwcd.AccountApplicationListener</listener-class> 
</listener>

The XML defines the name of the class that receives the events, there is no need to define the name of the class of the event. The container will look at the class and register it as a Listener depending on the interface that it implements.
In the example: only events of type ServletContextEvent will be handed off to the AccountApplicationListener class.
