prompt user

[zeero]

Hi all, I have a form in jsp that adds info into a database (insert into..) However, as of now I have it set with try catch blocks to capture and display errors on another page instead of getting the apache error pages. I want it to so instead of getting the duplicate key error message to prompt the user if he wishes to update instead. So in that particular catch block would I redirect to a new page to allow an update? If so, how?
I'm sure there are a few ways of doing this, but any suggestions would be appreciated. Hope this makes sense Thanks.

In a situation such as this, I would probably query the database first and determine if a user prompt is necessary, then write the following two HTML forms in if/else blocks:

(1) if(promptNecessary){prompt user, set hidden form element with response, then submit to the next page, using the user's response to determine how to draw it;}

and

(2) else{immediately redirects to main page if user prompt is not necessary.}

'hope that's useful.
