Hi,
perhaps you should add :
<%@page errorPage="True%>

at top of your JSP files.

and
"
<error-page>
<error-code>403</error-code>
/default.jsp
</error-page>
<error-page>
<exception-type>java.lang.Exception</exception-type>
/error.jsp
</error-page>
<error-page>
<exception-type>java.sql.SQLException</exception-type>
/sqlException.jsp
</error-page>

"
at web.xml

hope you are happy

Thanks for reply,
Yes I'm using <@errorPage="errorPage.jsp"@> and <@isErrorPage="true"@> in error page.
Without <error-page>...</error-page> in web.xml I get error in regular html page, not the errorPage.jsp.
When I add <error-page>...</error-page> I get empty html page and in log file
I see another error (not related to exception I throw from my code):

It's really show-stopper, I can't release this app like this.
Is it Jetty problem or jboss? Or maybe mine :-(

hope you happy

I guess I'm not...

Hi, as my understanding:

<@errorPage="errorPage.jsp"@> is used to forward the page error to errorPage.jsp, and

<@isErrorPage="true"@> seems that this JSP file can receive and display Exception information.

so,you should add <@isErrorPage="true"@> to errorPage.jsp,
or it display empty page without Exception info.

if you use <error-page/> tag you not need to add <@errorPage="errorPage.jsp"@> in every jsp, because system can automatically capture all Exception info to forward to error-page file.

in addition, the NullPointerException in log file is from your JSP file,not errorPage.jsp

maybe above is useful.

5. Re: Can't use errorPage. Any idea why?

l.g. Sep 13, 2002 10:48 AM (in response to l.g.)

The problem was using filters. If in filter exception is thrown then errorpage does not triggered by the system,
so I have to manually forward to errorpage. :(
