One approach you might consider is trying to use the get method for the first time the page is called and then using the post method for each subsequent call. In your JSP you could then check to see how the request was sent and react appropriately.

Dubuisson, Jr. [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 08, 2002 7:48 AM To: [EMAIL PROTECTED] Subject: Checkboxes I have a checkbox question. I’m trying to retreive a value from an HTML checkbox in my JSP code. I want the checkbox to have 3 states: 1) null meaning the page is hit the first time; 2) checked with a value of “Y”; 3) unchecked with a value of “N”. What I seem to be getting are the first two and not the third. Instead of showing an unchecked value of “N”, I get just a value of null. If a checkbox is set, you’ll get a request parameter value for it. If it is not checked, you will not get a request parameter value for it. That’s how it works. Your code which reads the request parameter values has to understand that. If you don’t see the parameter, the box wasn’t checked. -- __________________________________________________________ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup "Free price comparison tool gives you the best prices and cash back!" http://www.bestbuyfinder.com/download.htm =========================================================================== To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".
