Hi Marc,
Hope I can help. I wrote that chapter and the examples. Sorry for any
confusion!
So what are you doing? I just tried those samples again and they work
fine.
Note that the illegal.jsp is the page you should request, which will
then throw the exception to the exceptInherits.jsp. The
exceptInherits.jsp is the page that generates the response (e.g.):
JSP Implicit Object: exception
In Tomcat Web Server/3.3 dev ( JSP 1.1; Servlet 2.2 ):
This particular exception has an inheritance tree of:
java.lang.ArithmeticException
java.lang.RuntimeException
java.lang.Exception
java.lang.Throwable
java.lang.Object
Here is the exception thrown in the calling page:
java.lang.ArithmeticException: / by zero
If you request the exceptInherits.jsp _directly_, then you will get a
stack trace in the browser, as you should. The root exception is a
NullPointer for the implicit "exception" object because no exception has
been thrown, so none exists. Furthermore, an error page can't act as
its own error page, which is what it sounds like you are attempting.
Does this make sense?
Best regards,
Scott S.
