ExceptionHandler handles, but no error output in JSP
Help please!
I have just integrated ExceptionHandler. It now
appears to handle exceptions (because stack trace is
no longer displayed in browser, when there is an
error) but no error is output in JSP
My jSP (TILES) has tags for actionErrors and
ActionMessages, which outputs errors/messages for
ohter things, but does not work for ExceptionHandler
error.
Can anyone please tell me why exceptionHandler errors
are not output in my JSP screen?
Please see my source code below.
Thank you.

Michael,
I do intend to log the error and will add the
functionality to do that later. My primary concern
for now is to give the user some information. My
problem is what additional step to take in order to
output the message on the screen - JSP (TILES).
Thank you.
Ola.

I just had the thought that this whole way of doing things may be
superior to logging with respect to debugging. Hmmm?

ExceptionHandler handles, but no error output in JSP(tiles)
Posted by "O. Oke" <re...@yahoo.co.uk>.
Help please!
I have just integrated ExceptionHandler into
struts-config.xml file. It now
appears to handle exceptions (because stack trace is
no longer displayed in browser, when there is an
error) but no error is output in JSP.
My jSP (TILES) has tags for actionErrors and
ActionMessages, which outputs errors/messages for
other things such as validation errors, but does not
work for ExceptionHandler in struts-config.xml file.
Can anyone please tell me why exceptionHandler errors
are not output in my JSP(tiles) screen?
Please see my source code below.
Thank you.
