RE: [JBoss-user] Throwing exception question....
Correction. According to the specification, the JSP dumps everything in a super-giant try-catch block so Exceptions and RuntimeException need not be declared. The solution is therefore to apply best practices: limit the amount of code in your JSPs to none or less if possible. I know that our application contains hundreds of pages and there is no "code" at all. We use tags and beans that you might define as a page-let: a bean whose sole responsibility is to provide an API for a given JSP page. That way everything is compiled and at most the JSP page calls inline methods on its pagelet. -Original Message- From: Pitre, Russell [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 14, 2004 2:07 PM To: [EMAIL PROTECTED] Subject: RE: [JBoss-user] Throwing exception question Right!but doesn't...

Re: [JBoss-user] Throwing exception question....
You'll need: public class MaxNumberOfRequestsException extends Exception rather than extends RuntimeException or whatever you are using to avoid declaring it as being thrown. RuntimeExceptions and Errors do not need to be handled.
