Wicket base webapp

After having some trouble finding a slim and small base layout in the web, serving as template for any Wicket application I might develop (without using Jetty or providing any "quickstart" framework), I'd like to post a solution using filters instead of the Wicket servlet (recommended as of Wicket 1.4+):

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app
      PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
      "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
  <display-name>Wicket Base</display-name>

  <context-param>
    <param-name>configuration</param-name>
    <param-value>deployment</param-value>
  </context-param>
 
  <filter>
    <filter-name>wicketbase</filter-name>
    <filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
    <init-param>
      <param-name>applicationClassName</param-name>
      <param-value>com.wicketbase.WebApplicationBase</param-value>
    </init-param>
  </filter>

  <filter-mapping>
    <filter-name>wicketbase</filter-name>
    <url-pattern>/wbase/*</url-pattern>
  </filter-mapping>
   
</web-app>


WebApplicationBase.java:

public class WebApplicationBase extends WebApplication {

  @Override
  protected void init() {
    this.getMarkupSettings().setDefaultMarkupEncoding("UTF-8");
    this.getRequestCycleSettings().setResponseRequestEncoding("UTF-8");
  }

  @Override
  public Class getHomePage() {
    return WebPageBase.class;
  }

  public static WebadminApplication get() {
    return (WebadminApplication) Application.get();
  }

  @Override
  public Session newSession(Request request, Response response) {
    return new WebSessionBase(request);
  }

}


WebSessionBase.java:

public class WebSessionBase extends WebSession {

  public static WebSessionBase get() {
    return (WebSessionBase) Session.get();
  }

  protected WebSessionBase(Request request) {
    super(request);
    setLocale(new Locale("de", "DE_EURO"));
  }


}


WebPageBase.java:

public class WebPageBase extends WebPage {
 
  public WebPageBase() {
    add(HeaderContributor.forCss(WebadminPage.class, "res/style.css"));
  }

  public WebSessionBase getWebSessionBase() {
    return (WebSessionBase)getSession();
  }
}


WebPageBase.html (just for completing this example):

<?xml version="1.0" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:wicket="http://wicket.apache.org/" xml:lang="en" lang="en">
<head>
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>

<body>
...
</body>
</html>


Ant build script:

<?xml version="1.0" encoding="UTF-8"?>
<project default="war" name="wicketbase" basedir=".">
 <property name="final.name" value="wicketbase" />
 <property name="src.main.dir" value="src/com/wicketbase" />
 <property name="src.web.dir" value="webapp" />
 <property name="lib.dir" value="lib" />
 <property name="build.dir" value="target" />
 <property name="build.main.classes" value="bin" />
 <property name="build.reports.dir" value="${build.dir}/reports" />
 <path id="build.classpath">
  <fileset dir="${lib.dir}">
   <include name="**/*.jar" />
  </fileset>
 </path>
 <target name="clean">
  <delete dir="${build.dir}" failonerror="false" />
  <delete file="${final.name}.war" failonerror="false" />
 </target>
 <target name="init">
  <mkdir dir="${build.dir}" />
 </target>
 <target name="compile" depends="init">
  <mkdir dir="${build.main.classes}" />
  <javac destdir="${build.main.classes}" target="1.5" source="1.5"
   srcdir="${src.main.dir}" classpathref="build.classpath" />
  <copy todir="${build.main.classes}">
   <fileset dir="${src.main.dir}">
    <include name="**/*.*" />
    <exclude name="**/*.java" />
   </fileset>
  </copy>
 </target>
 <target name="war" depends="compile">
  <war destfile="${build.dir}/${final.name}.war" webxml="${src.web.dir}/WEB-INF/web.xml">
   <lib dir="lib">
    <include name="*.jar" />
   </lib>
   <classes dir="${build.main.classes}" />
   <fileset dir="${src.web.dir}">
    <include name="**/*" />
    <exclude name="**/web.xml" />
   </fileset>
  </war>
 </target>
</project>


The folder layout of the webapp is as you would probably expect it. Wicket jar's go to "WEB-INF/lib", your classes and the HTML go to "WEB-INF/classes/[package]".
