When deployed on Tomcat 6.0 the wicket example, it is not building the War with the necesary wicket jars. They are missing in the WEB-INF/lib directory.

When the war is loaded in tomcat an error in the loading of WEB-INF/components.xml is thrown:

java.lang.RuntimeException: error while reading /WEB-INF/components.xml
