RE: Probelm with global-exceptions routing.
Dear Sreekant,
When I programmed my RequestProcessor a about 2 weeks ago, I found
processRoles() throws exceptions which are absolutely not catchable by any
Exceptions listings in struts-config.xml. So, I wrote better Java code to
catch things like null pointers. Or (pardon the thick sarcasm), you could
try/catch it yourself in your method. The reference to my filter is:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg78455.html
I did one typo, in step #3 i wrote 'scope='
when it should be 'roles=.'.
I've never had one login-related exception (null pointer or otherwise) since
the day I wrote the above RequestProcessor class, which I have in place and
test under every day. The hard part for me was figuring out how to redirect
to the page of my choice, which you'll find in my example code.
Regards,
David
