import java.io.IOException;
import java.sql.DriverManager;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.mysql.jdbc.*;

*// Here,in below 2 statement, I got 2 the same error as shown in title*

**Connection con = DriverManager.getConnection("localhost:3306", "root","simple");               
Statement stmt = con.createStatement();**
    if(stmt.execute(sql)){
    System.out.println("Sql Statement Executed.");
    }
    else
    {
        System.out.println("Sql Statement not eexecuted.");
    }
    if((unm != null) && (pwd != null)){
        RequestDispatcher rd =request.getRequestDispatcher("Home.jsp");
        rd.forward(request, response);
    }
}

}

我试图将我的数据从servlet发送到mysql服务器但在servlet中我得到了

错误:"类型不匹配:无法从java.sql.Connection转换为com.mysql.jdbc.Connection"

任何人都可以建议我删除代码错误的方法.我不知道.
