Answer 2

Add MySQL JDBC driver (you can get it here: http://dev.mysql.com/downloads/connector/j/) to application's classpath and remove unnecessary piece of code:

    try 
    {
        Class.forName ("com.mysql.jdbc.Driver");
    }
    catch (ClassNotFoundException e)
    {
        System.out.println ("Could not load the driver");
    }

Answer 3

You can try to connect directly with MySQL JDBC driver

com.mysql.jdbc.Driver driver = new com.mysql.jdbc.Driver();
Connection conn = driver.
            connect("jdbc:mysql://localhost/test?user=root&password=root", null);

if this code does compile you are missing MySQL JDBC driver on the classpath
