I'm working on some Java EE application (with GWT and the smartclient widget library), and I'm running against a few simple Java EE related problems (this is my first Java EE project).

I know how I can send and receive data from my server side Java with RPC calls, I know that I should use JDBC to connect to my database, but I have no idea whatsoever on how to set up this database in a way I can use it in my Eclipse project.

Some help here would be appreciated :)
