Piece of cake, you can create a page that handles authentication
checking as follows:
public abstract class AbstractSecurePage extends AbstractPage implements
PageValidateListener {
InjectState("visit")
public abstract Session getSession();
public void pageValidate(PageEvent event) {
//check user permissions here e.g.:
if (!getSession().isUserLoggedIn()) {
throw new PageRedirectException("LoginPage");
}
}
}
Hope that helps :D
