You might investigate these links:
Section 4.5 here:
http://struts.apache.org/userGuide/building_controller.html
and the corresponding javadoc here:
http://struts.apache.org/api/org/apache/struts/action/ExceptionHandler.html
Since I really don't know off the top-of-my-head...
Good luck!

Please respond to
"Struts Users Mailing
List"
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?
