So, you are calling your ejb or delegate class from your formbean to get the static data? And how do you access it from the jsp? I am just curious.

The "clean up" part is tricky, because you can't be sure of when the data can be cleaned up, and you can't rely on the user to click somewhere that'll fire an action to make that cleanup... Around here, because we have lots of "static" data on the pages and querying the remove server (EJB) for these data would be very onerous, we do the following: - All our form beans are in the session scope. This way, we populate them with the necessary collections and other data needed for the JSP, and we don't need to re-populate this data in later requests from that user. - No data is stored outside the form bean. Everything on the JSPs is loaded from the form bean. - On each request, we look for the objects stored in the user's session and, in case it is a form bean but is not the form bean of the current request, it is deleted. The last part may seem "heavy" since in every request I loop through everything in the session, but, due to the way we implemented (everything in the bean) we generally have 2 or 3 objects in the session (the form bean, the "Locale" object and the "token" for preventing repeated requests from being processed). Also, we have some mechanisms for when we do not want a form bean to be erased from the session (since all our forms use session scope, there are times when we may need more than one bean in the session). It may not be the most beautiful thing to do, but it has been working very well. =) -- []'s Marcelo Vanzin Touch Tecnologia [EMAIL PROTECTED] "Life is too short to drink cheap beer" -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
