People normally do:
Class.forName("oracle.jdbc.OracleDriver");

con = DriverManager.getConnection(
"jdbc:oracle:thin:@hostname:1521:db", "www_user", "www_user" );

I've also seen 'dnldthin' instead of 'thin'. Mysql is using so well
for me these days, I see little need to use Oracle. Just can't get
any large contracts any more these days anyway.
