It's not really a "workaround". The only thing special about managed beans are the fact that they can get created for you, as a side effect of evaluating an expression. But after creation the server actually puts them into one of the normal scopes: * Request scoped managed bean --> request attribute * Session scoped managed bean --> session attribute * Application scoped managed bean --> ServletContext attribute Therefore, using a ServletContextListener to preinitialize your application scoped managed bean is fine ... all you have to ensure is that the attribute name you store it under is the same as the managed bean name. Later on, then, the managed bean facility will find that the bean already exists, so it will not bother to create it. Craig
