Dont worry about the Z. Apparently you have the latest version of Struts for development but not when you deploy. You might want to check the version that you have deployed with to make sure. -Tim
-----Original Message----- From: Mervin Williams [mailto:[EMAIL PROTECTED] Sent: Monday, March 03, 2003 4:58 PM To: 'Struts Users Mailing List' Subject: RE: isEmpty() Method Not Working? I put a try/catch block around the "if(!errors.isEmpty())" call, but the catch block was never entered, and the exception occurred. Below is the stack trace for the error. I do notice something strange in the stack tracke: in the "Root Cause" portion of the stack trace, the NoSuchMethodError refers to a method named "ActionMessages.isEmpty()Z". Where is the "Z" coming from - I do not have a "Z" at the end of my method call. -------------------------------------- 2003-03-03 15:48:18,909 ERROR [org.jboss.web.localhost.Engine]
