这是我的jsp页面

这是我的道课

package dao;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;

import connection.Connect;
import model.Driverreg;

public class driverdao {

    private Connection connection;

    public driverdao() throws Exception {
        connection = Connect.getConnection();
    }

    public void adddriver(Driverreg d)
    {
        try {
            PreparedStatement p=
            connection.prepareStatement("insert into drireg(did,dname,daddress,dgovtidno,dgtype)values(?,?,?,?,?)");

            p.setInt(1, d.getDid());
            p.setString(2, d.getDname());
            p.setString(3, d.getDaddress());
            p.setInt(4, d.getDgovtidno());
            p.setString(5, d.getDgtype());

        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

我已经创建了该jsp页面用于驱动程序注册，并且想将在表单中输入的数据保存到数据库中，为此我已经在dao类中编写了adddriver方法。我已经创建了pojo Drireg，并用于连接mysql Connect类。当用户单击“保存”按钮时，请求应转到此dao类，但是在执行这些操作时出现错误。该怎么办？

我想在用户单击保存按钮到数据库时保存数据

错误是

HTTP Status 404 - /selflearn/dao/driverdao


type Status report

message /selflearn/dao/driverdao

description The requested resource is not available.


Apache Tomcat/8.0.9

如何将请求从jsp页面转移到dao类
