[Geoserver-devel] option "Hello" from the left panel not displayed

Hi all
I want to build this example in the module "Implementing a Wicket UI Extension", but the option "Hello" from the left panel, resulting in this example does not show me. Acontinuacion describe the steps that follow.
I have windows 7 operating system. Download the source code with geoserver "git clone git :/ / [github.com](http://github.com) / geoserver / geoserver geoserver.git" command, I get version "master" and create the java project with maven eclipse. I am recreating the example in "Implementing a Wicket UI Extension", take the structure of the "geoserver \ src \ community \ hello_web" folder to build the sample with maven. I built the project with maven successfully, then add the hello_web dependence inside the pom.xml file this in the "geoserver \ src \ web \ app" folder, went back to generate web \ app with maven, the "hello_web-1.0 file -SNAPSHOT.jar "now appears in the" geoserver \ src \ web \ app \ target \ geoserver \ WEB-INF \ lib "and in the file" geoserver \ src \ web \ app \ target \ geoserver.war ". Inside the file "hello_web-1.0-SNAPSHOT.jar" file "applicationContext.xml" appears. The problem is that when you restart the geoserver project and enter with admin user, the hello option in the left pane does not appear as it should occur. The structure hello_web pom.xml file is the following:
	  <project xmlns="[http://maven.apache.org/POM/4.0.0](http://maven.apache.org/POM/4.0.0)"
         xmlns:xsi="[http://www.w3.org/2001/XMLSchema-instance](http://www.w3.org/2001/XMLSchema-instance)"

      </project>

And This is my file HelloPage.java
package org.geoserver.helloweb;

import org.apache.wicket.markup.html.basic.Label;
import org.geoserver.web.GeoServerBasePage;

public class HelloPage extends GeoServerBasePage {

    public HelloPage() {
        add( new Label( "label", "Hello World!" ) );
    }
}

Could you please help me find the error. Thank you very much.
