You can create your own tag to wrap the html tag, and in the tag class to process any attribtue you need. If you want to build a whole view framework, I guess to use tag library is necessary and might be the best way to take. ----- Original Message ----- From: "Witold Iwaniec" <[EMAIL PROTECTED]> To: "JDJList" <[EMAIL PROTECTED]> Sent: Thursday, June 06, 2002 12:16 AM Subject: [jdjlist] Servlet request and HTML element attributes
