Hi Gal

Thanks for the help.

I was wondering if you knew where I can find complete documentation on the
server.xml
file.  I want to write a Security Request Interceptor for one web app.
Currently
in each JSP page I include a header file that have a bean scoped to the
session.  When
anybody enters the session, I look if the person is registerd for this
session.  If not
I display a Login.  I don't know if this warrants a RequestInterceptor
rather than a
putting a check in every JSP page.

I appreciate your help
Manie

P.S. Pardon my delicious English
