RE: Session management with Struts
In that case i would advise you to maintain a Hashmap/Hashtable of form objects wrapped inside an Global Action form (session scope). Every time a user opens a new browser window, i am sure that a unique id can be generated for the new window ( i have seen a posting on this list a month back where somebody has explained that using javascript we can generate a unique id for every new web browser that was opened by the user). Store this id in a hidden name=value pair. Check the mail archives as to how to do this. Over-ride your ActionServlet service() method where you initially check the id of the browser window. (btw the form objects wrapped inside the GlobalActionForm object will be mapped to these id's.) . When the corresponding form object is found, then you populate the data in that form object. If no form object is found, then create a new form object and populate the data in that form object (using reflection). Struts has libraries to do this. This is a complicated way of doing it, but the best that could pop out of my brain this time...(morning blues. I could use some caffeine). cheers, Amar.. -Original Message- From: TJM Todd McGregor [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 09, 2001 5:44 PM To: '[EMAIL PROTECTED]' Subject: RE: Session management with Struts But that's exactly my problem.

RE: Session management with Struts
Hi, I think you want to start looking at the 'tokens' functionality that comes with struts. We did something similar in my last non-struts project and it worked very well.
