Tomcat gurus: I still have not had a response to my original question of 05/09/01 about DEFAULT TC4 error return page, but while looking further into the use of web application <error-page> directives in the app's web.xml, I have come across the following problem: 1) Using a JSP page to set a parameter via form with same page as action, perform a divide of 17 by the parameter value. When I enter 0 for the parameter, the expected javax.servlet.ServletException / by 0 is triggered, with root cause of java.lang.ArithmeticException / by 0. However, I have placed into the web.xml the following: <error-page> <exception-type>javax.servlet.ServletException</exception-type> <location>customerrorSE.html</location> </error-page> (I have also tried permutations of the <location> value, with no avail. The html file is in the webapps root directory.) Adding a directive for the Arithmetic exception: <error-page> <exception-type>java.lang.ArithmeticException</exception-type> <location>customerrorJE.html</location> </error-page> also has no effect. So, does anyone know why this does not appear to be working? -------- Original Message -------- Subject: Is it possible to set the GLOBAL default error page for Tomcat 4? Date: Wed, 09 May 2001 17:34:03 -0500 From: John Upham <[EMAIL PROTECTED]> Organization: MOREnet Systems & Programming To: [EMAIL PROTECTED] BCC: [EMAIL PROTECTED], [EMAIL PROTECTED] I understand the use of the error-page directive in an application web.xml, but we are interested in changing the default error-page returned globally by Tomcat 4. We would like to return a "user-friendly" error response with a customized error page that does not include the stack trace info (but from which we can do informational logging). Is it possible to declare a default error-page value in the Tomcat server.xml (or other config file)? Barring that, is it possible to create a custom error handler class to override the Tomcat error handler? Thanks for any help, jbu -- John B.
