        catch (SQLException ex) {
            ex.printStackTrace();
    }
    return conn;
    }

    public static void main(String[] args) {
        Connection conn;
        DBConnection db = new DBConnection("localhost","8889","test","test","test");
        conn = db.establishConnection();
    }
}

I use this code so many times, it was only fair to finally do this!
