Hello,
See:
http://tomcat.apache.org/tomcat-5.5-doc/config/context.html
in particular, the section on antiResourceLocking. Note the caveats.
Otherwise, undeploy the app, update your jars, and redeploy.
Thanks.

Any fool can paint a picture, but it takes a wise person to be able to

Actually I want to update the jar with the latest one inside 'lib'...and
want to make our app hot-updatable. what would be a good idea for that?
