Java EE (Java Enterprise Edition) General Discussion

My host is running Tomcat 4.1.24 on an Apache 1.3.29 server, and tomcat (supposedly) refreshes its servlets every twelve hours. If I upload a new .war file it will deploy it to a folder of the same name almost instantly, however if I then make changes to that .war file it will not deploy it over the old installation. This would lead me to believe I need to undeploy the old version of my webapp before the updated .war file can be deployed.

It doesn't even deploy the updated .war file when tomcat refreshes, as I've waited over 12 hours without the updated .war file being deployed.

Bearing in mind that I do not have access to my host's tomcat config files and, to make matters worse, they say they don't run the tomcat manager tool on their servers, how can I undeploy my old version of my webapp so that I can deploy the new one?

Thanks,
Andrew.
