用eclipse写jsp&servlet时，连接数据库出错

[小思緖兜兜转转]

用eclipse写jsp&servlet时，连接数据库出错：

加载驱动成功
java.sql.SQLException: No suitable driver found for jdb:mysql://127.0.0.1:3306/db_jsp
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at com.shi.util.Util.getCon(Util.java:17)
at com.shi.util.Util.main(Util.java:36)
Exception in thread "main" java.lang.NullPointerException
at com.shi.util.Util.main(Util.java:43)



程序代码如下：
package com.shi.util;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class Util {

private String driverName="com.mysql.jdbc.Driver";
private String name="root";
private String password="123456";
private String db_url="jdb:mysql://127.0.0.1:3306/db_jsp";

public Connection getCon() throws Exception{
Class.forName(driverName);
System.out.println("加载驱动成功");
Connection con=DriverManager.getConnection(db_url, name, password);
return con;
}

public void close(Connection con){
if(con!=null){
try {
con.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

public static void main(String[] args) {
Connection con=null;
Util db=new Util();
try {
con=db.getCon();
System.out.println("连接成功");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
con.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}

这样不行啊，要学会自己看错误提示， 你这里 jdb:mysql://127.0.0.1:3306/db_jsp中，把jdb改成jdbc就行，谢谢！！！

楼上正解，没错
