When
I try to access to a Database through the connector it fails if I leave
it inside WEB-INF\lib, but everything works if I copy the jar in the
lib folder of the apache distribution. Is there any other way to let a
web app access to a lib without having to copy the jar in apache\lib?
I'm using apache 6.0.18 and the exception I receive when I try to
access the db is:
