We delete the war file before stopping tomcat to give Tomcat a chance to
auto-undeploy the application automatically.

I just read last night that auto-deploy/undeploy carries a performance
impact, is the performance impact really that significant just for
monitoring a directory?

The problem as I am made to understand from the developers is that the
context name is dependant on the application name and that specifically
specifying a context name does not do the trick. I have not tested this
myself yet, but plan to do so.
Even though the file name in the script are the same it is a different file
or different version at least of the same application.

An interesting idea... How would you make your tomcat unavailable during the
re-deployement of a new application?
