How do you upload to the server? Depending on your vendor you may have both a WAR and directory structure deployed and it is ignore the one you are deploying. Start by cleaning out all of the web applications first, start from scratch.
Hmm. I ftp the completed class files and web.xml file to the appropriate directory. What annoys me is the hosting company telling me its a problem with my code when it works on my machine swimingly. Im seriously considering just keeping the domain name and hosting from my machine!
