Custom Error Page for Error Code 500 in Tomcat

[Ram Balasubramaniam]

Hi
I am trying to have a custom error page for the HTTP 500 error code . I am using Tomcat 3.2.3
In my application
/tomcat/webapps/myapp/WEB-INF/web.xml I have added the following code.

 
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
    "http://java.sun.com/j2ee/dtds/web-app_2.2.dtd">
<web-app>

<servlet>
    <servlet-name>DisplayChart</servlet-name>
    <servlet-class>com.jrefinery.chart.servlet.DisplayChart</servlet-class>
 </servlet>
 <servlet-mapping>
 <servlet-name>DisplayChart</servlet-name>
 <url-pattern>/servlet/DisplayChart</url-pattern>
</servlet-mapping>
<error-page>
     <error-code>404</error-code>
     <location>/errorpage.html</location>
 </error-page>
 
 <error-page>
     <error-code>500</error-code>
     <location>/errorpage.html</location>
 </error-page>
</web-app>
 

When I restart the server , I am able to see error page for 404 but 500 does not seem to work. I am really confused.Am i Doing any mistakes in web.xml.
My error page is in the /tomcat/webapps/myapp/errorpage.html.
I even tried using errorpage.jsp as suggested by some one in the forum , but it dint work .
Can some one point out the mistake.
Thanks
Ram
