This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
All form fields come in as either java.lang.String (or String with getParameterValues).
To insure that a field is numeric, you can either create a regular expression and match it against that or try to convert it to an int with Integer.parseInt from with a try/catch block. [ March 27, 2008: Message edited by: Ben Souther ]
