Your problem is here:
String root = getServletContext().getRealPath("/");
you are setting the upload path to the containers path, not a default path but the place where the server started from. You can make the upload path anything you want it to be, it depends on your needs and configuration.
You could create a system property with the directory of your choice, you could set it as a dynamic property in a JBoss configuration file (not sure what that would be for JBoss4).
