That's not difficult:

1.) Establish a ssh connecton from the client formwaarding to the
    dbhost (port is the port number on the local host being forwarded):
    ssh -L port:dbhost:5432 dbhost
    or (as I regularly do)
    ssh -2 -n -N -L port:dbhost:5432 dbhost
    You'll probably have to set up some identities to make this
    work conveniently.

2.) Then you can connect to the remote database by using
    db = DriverManager.getConnection
         ( "jdbc:postgresql://localhost:"+port+"/"+dbname, user, pass );
    Where post is the local port and dbname is the (remove) database
    name.
