Re: Session based object, accessible to all classes.
Hi, Eh, store the object in the session with session.setAttribute(name, object) retrieve it with (cast-to your object)session.getAttribute(name). Or is this a too simple answer for your problem ?

Is there a common way of sharing a data structure across these classes? I want to instantiate it when a user logs in, add to it from one class, then retrieve data from another class. This data will vary across users, hence is not common to all sessions. TIA, Regards DaveP. snip here * - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Or is this a too simple answer for your problem ? javax.servlet.http Interface HttpSession ? Is that the one you mean Werner? Just give it any recognisable name and it returns the object based on this users session? Sounds about right, so long as it is session based, which it seems to be from the javadocs. Much appreciated.

Think of session as another scope, like request or application: it's a bucket in which you can store any old Object (just be sure to cast it back to your expected object when you get it back). Session scope is special because it is bound to, well, a session, which should be a particular instance of a particular user account. (i.e. if bob logs in twice from different browsers, he will likely have two different sessions.) -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
