DB CONNECT类未找到java类MYSQL

Question

我的代码不能用java和jsp plz帮帮我

public class DbConnect {
    Connection conn = null;
    ResultSet rst;
    java.sql.Statement stmt;
    String url="jdbc:mysql://localhost:3306/";
    String dbName="teljo";
    String driver="com.mysql.jdbc.Driver";
    String userName="root";
    String password="";

    public Connection getConnect(){
        try {
            Class.forName(driver).newInstance();
            System.out.println("driver loaded sucessfully");
            conn=DriverManager.getConnection(url + dbName,userName,password);
            System.out.println("connect to the data base");
        }
        catch (ClassNotFoundException ce) {
            System.out.println("driver loading failed"+ ce);
        }
        catch (Exception e) {
            System.out.println("error in connection to database");
        }
        return conn;
    }
}

这是我的连接代码db class。 mysql连接notconnect是做什么的？我使用eclipse IDE， 输出就是这个

 driver loading failedjava.lang.ClassNotFoundException: com.mysql.jdbc.Driverjava.lang.NullPointerException

请将外部MySQL Connector / J添加到您的项目中。这些可以解决问题。

下载mysql jdbc jar的链接：https://dev.mysql.com/downloads/connector/j/
