Java EE (Java Enterprise Edition) General Discussion

I have a completed JSP/servlet website that I'm trying to deploy on a webhosting site but I'm having some problems. The root directory is apparantly /html and then there's a /web-inf folder in that that containts a /classes and /lib folder. I've tried placing the war file in the /html and the /web-inf folder and having them restart tomcat, but it won't automatically uncompress the war file. I don't have access to any of the server configuration files. Is there a line of code I can use to telnet in and manually extract the war file?
