Yeah, I agree with you .......I should and it works!!!!
To check our understanding this what I did this time. I updated my
configuration to
<servlet-mapping>
<servlet-name>SessionExample</servlet-name>
<url-pattern>/servlet/SessionExample</url-pattern>
</servlet-mapping>
<error-page>
<exception-type>java.sql.SQLException</exception-type>
<location>/servlet/SessionExample</location>
</error-page>
As you can see now it's redirected to a servlet.
Could you try some thing like this
1. try a new servlet, which is very simple.
2. test this servlet by entering it's URL in your browser.
3. if this servlet is working fine then map it's "<url-pattern>" to your
<location> XML element under <error-page> as shown in the above sample.
I hope this should work. It worked for me (I tried this on
jakarta-tomcat-5.5.4)

code does not work. Theoretically my code should work
right?
