Shoot. Didn't read your message closely enough. This only applies to
exceptions thrown within a JSP page and handled by the JSP exception
handling mechanism, and you're talking about the Struts exception
handling mechanism.
Sorry 'bout the noise.

From Section 2.4 of the JSP 1.2 specification:
"If the errorPage attribute of a page directive names a URL that refers
to another JSP, and that JSP indicates that it is an error page (by
setting the page directive’s isErrorPage attribute to true) then the
'exception' implicit scripting language variable of that page is
initialized to the offending Throwable reference"

JC,
Thanks. This I know. But...
If I do this in struts-config:
<global-exceptions>
<exception
key="exception.general"
type="java.lang.Exception"
path="/error.jsp"/>
</global-exceptions>
Then error.jsp will be called when an Exception is thrown by an Action
method. In error.jsp I can print a general message. I would like to be
able to also print out stack trace info in the jsp. Does the mere fact
of designating error.jsp as my error hadling page mean that struts has
put the Exception somewhere, e.g. the request? If so under what key? Or
must I do all this myself:
<global-exceptions>
<exception
key="exception.general"
type="java.lang.Exception"
path="/error.do"
handler="com.plok.blah.ExeptionHandler" />
</global-exceptions>
In ExeptionHandler I log the problem ad then put the formatted Exeption
stacktrace on the request, or something similar?

Miles, you can capture a stack trace from any throwable using a
technique
like:
ByteArrayOutputStream baos = new
ByteArrayOutputStream();
(new Throwable(s)).printStackTrace(new
PrintStream(baos));
return baos.toString();
The result could be logged.
Hope this helps.

Please respond to
"Struts Users Mailing
List"
The html:errors tag will display a generic message but how can I
display the details of what went wrong (e.g. the Exception's
stacktrace) in the designated error jsp?
What are the options?
Can someone point me at some docs that go into this in more detail?
Thanks,
