One way is to have a old and new variable in your form bean. Leave all the old variables empty when the form bean is sent to the jsp for the first time. When the user makes their changes and submits them check in the set method of the form bean to see if the data changed. If it did then save the original value to the old variable and then set the new value into your variable.

Is it possible to use the form bean that stores our old data, and the form that is populated by the new data for comparison? I hope i am not confusing. thanks again. -----Urspr�ngliche Nachricht----- Von: Keith Bacon [mailto:[EMAIL PROTECTED]] Gesendet am: Friday, December 14, 2001 3:00 PM An: Struts Users Mailing List Betreff: Re: possible to keep old and new values inside of a form bean Hi Fehmi. I think you should do things like this in your Action class rather than the Form bean - which should strictly be used for data that goes from forms to Action class & vice versa. This is part of your business logic (or maybe of DB integrity checking) - so if your system is large(ish) you'll want to have that logic in classes called from your Action class.
