Hi, Because this processing servlet of yours itself had an error. A JSP file by default is processed by Tomcat's JSP servlet, not your Router servlet. Accordingly, it's not subject to your custom error handling mechanism. A more standard way to do this is declare an <error-page> for 404's in your web.xml, and/or an errorPage for the specific JSP page in the JSP page itself.
