Java and Database Connectivity

Getting a Connection

• Need a URL, a username and a password
• Might throw an exception
• No simple means of working out what the exception means

    Connection c;

    try
        {
            c = DriverManager.getConnection( url, user, pass);
        }
    catch ( SQLException e)
        {
            out.println( "Could not connect to database " + url);
            out.println( "Does it exist? Are you authorised?");
        }
