Putting Java into cPanel?

I'm working on coding a game a friend of mine runs (currently by hand changing HTML). He hosts on cPanel and the language I'm most familiar with is Java. I'm completely new at programming for websites.
Just a few questions:

-Can this even be done? I looked into it, and found out some things about Applets, but they seem very odd (different?) to code, but I suppose I can make due, if only I knew how to implement them in cPanel.
-How can I access information from the database? I've looked into JDBC, but again, I don't know how to integrate it or if it will even work.

Any explanations or help is appreciated. Thanks.
