I have a Google Appengine/Guice/Wicket Application. My problem is that due to the mapping I can\'t access the /_ah/admin Page anymore.

I know this is is a pretty old question with an accepted anser, however the solution is more straight forward than URL rewriting. In your Guice servlet module you can pass configuration parameters as follows:
Map wicketParams = new HashMap(3);
wicketParams.put(WicketFilter.IGNORE_PATHS_PARAM, "/_ah/*");
wicketParams.put(WicketFilter.FILTER_MAPPING_PARAM, ROOT_FILTER_MAPPING_URL);
filter("/*").through(GuiceWicketFilter.class, wicketParams );
