I'd like to make a simple-ish website that is essentially a small game. Key strokes are to be processed and sent to a server (already acquired and should support SQL and JSP, I believe) which then translate to a location and written to the DB.
SQL queries are to be used to retrieve these locations and written to other clients connected to the website. Their page is to be updated with these locations.
EDIT: I was just informed I will not be able to use WAR files on the server. I'm not big on php and really don't like developing with it, can I still use Java?
