violates loader constraints

[Alice Han <al...@villanova.edu>]

I have gone through the entire archive about this topic and
none of them give a final answer.
I have the web application in  Tomcat 4  working for a couple
of days, but  I'm getting a strange error, and frankly I don't
know what's causing it.   The vusecuity.jar in WEB-INF/lib  is not standard api.

Help?
