You're perfectly right, but the Application can be either MyWebApplication or WicketTester, so the Page doesn't know the exact type of the Application. > > And about the Wicket-Spring extension, is there a > > documentation available? > > It has JavaDocs and an example project, and there is a WIKI > page: http://www.wicket-wiki.org.uk/wiki/index.php/Spring. Thanks, that was exactly what I was looking for. And you see in the examples that the following construct is used: ((MyApplication)getApplication()).getContactDao() However there is also a discussion about Injector, maybe it's a better approach than MetaData, and no cast is necessary in this case apparently.
