RE: Error 500 with stack trace

Hi,
 
I've noticed that there's a difference on how Resin 3 handles
errorpage-things compared to Resin 2. It seems that if there is an error
in your JSP after something is already written to the response and its
buffer has been committed, the errorpage cannot be shown anymore via the
forward mechanism. This is propably what the spec expects, but Resin 2
didn't work like this...

To clarify my two questions further...

 

1) How do you get the custom error 500 page to display? I've got the
following in my web.xml:

 

<error-page>

    <error-code>500</error-code>

    <location>/500.jsp</location>

  </error-page>

 

... but when an 500 error is thrown I get the following error message:

 

java.lang.IllegalStateException: forward() not allowed after buffer has

committed.

2) How do you gain access to the stack trace of the original exception
so it can be displayed?

 

 

Thanks - G

Does anybody know how to setup Resin with a custom page for an error 500
that displays the stack trace?

 

Thanks - G
