  -Since this is a very basic example of a Wicket application, we don't need to specify anything inside the _init_ method. The home page of the application is the _HomePage_ class. In the next paragraph we will see how this page is implemented and which conventions we have to follow to create a page in Wicket.

   If we prefer to use a servlet instead of a filter, we can use class _org.apache.wicket.protocol.http.WicketServlet_. See the JavaDoc for further details.
   
  
positive.code: protected void init()

  This method is called when our application is loaded by the web server (Tomcat, Jetty, etc...) and is the ideal place to put our configuration code. The _Application_ class exposes its settings grouping them into interfaces (you can find them in package _org.apache.wicket.settings_). We can access these interfaces through getter methods that will be gradually introduced in the next chapters when we will cover the related settings.
  
  The current application's instance can be retrieved at any time calling static method _Application.get()_ in our code. We will give more details about this method in <<requestProcessing.adoc#_the_director_of_request_processing_requestcycle,chapter 9.3>>. The content of the application class from project HelloWorldExample is the following:

negative.code: public abstract Class<? extends Page> getHomePage()

  As you may guess from its name, this method specifies which page to use as a homepage for our application.
  Another important method is _init()_:
