There is one thing about adding filters that wasn't quite obvious to me.
If you application is just a filter (e.g. Wicket) then you still need to
add a "NullServlet".

I use something like this to add filters:

int options = ServletContextHandler.NO_SECURITY;
ServletContextHandler context = new ServletContextHandler(server, "/",
options);

context.addFilter(MyFirstFilter.class, "/*", FilterMapping.REQUEST);

FilterHolder secondFilter = new FilterHolder(MySecondFilter.class);
