Thanks all for the responses. I have one more question though. I am working with the wicket framework and i know it already has an internal guice servlet module defined somewhere. (wicket-guice sub project) . I would like to inject the Persist Filter . Is it possible to have more than one servlet module so that i can later create my inject using something like Guice.createInjector(new ServletModule1(), new ServletModule2, new PersistenceModule()) e.t.c ..
Kind regards.
