내 프로젝트에서 사용자 테이블에서 계정을 삭제하는 계정을 취소 취소 기능을 만들고 있습니다. 사용자 테이블 이름은 newuser입니다.Exhausetd 결과 집합 Percentular 열에서 가져 오는 중 오류가 발생했습니다.

이 Cancelaccount 서블릿, 나는이 열려 계정에 등록 된 암호를 사용하여 현재 입력 암호와 일치하는 것을 시도하고있다 : 같은 cancelaccount JSP로 보인다. 그들이 계정을 취소해야할지 일치하면 서블릿 코드는 그렇지 not.So :
import getset.Getset;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.SQLException;
import accessdb.Dao;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
public class Cancelaccount extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
// TODO Auto-generated method stub
Getset g = new Getset();
Dao dao = new Dao();
PrintWriter pw = response.getWriter();
String password = request.getParameter("password");
HttpSession session = request.getSession();
String userid = (String)session.getAttribute("userid");
if (password.equals("") || password.equals(" "))
response.sendRedirect("UserHome.jsp");
g.setuserid(userid);
g.setloginpassword(password);
try {
String password1 = dao.getregpasswordbyuserid(g);
if (password1 == password) {
dao.cancelaccount(g);
pw.println("<html>Your Account has been successfully cancelled from the system.<p>" +
"Click here to go to <a href=\"WelcomePage.jsp\">Start Page</a><html>");
session.invalidate();
} else {
response.sendRedirect("UserHome.jsp");
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
DAO 기능 코드는 다음과 같습니다
public void cancelaccount(Getset g)throws ClassNotFoundException,SQLException{
//Delete a user from NEWUSER TABLE AND MEALDB TABLE
Connection con=Dbconnection.getConnection();
String userid=g.getuserid();
PreparedStatement pstmt=con.prepareStatement("delete from mealdb where userid=?");
pstmt.setString(1, userid);
pstmt.executeUpdate();
PreparedStatement pstmt1=con.prepareStatement("delete from newuser where userid=?");
pstmt1.setString(1, userid);
pstmt1.executeUpdate();
}
public String getregpasswordbyuserid(Getset g)throws ClassNotFoundException,SQLException{
//GET PASSWORD BY USERID
Connection con=Dbconnection.getConnection();
String userid=g.getuserid();
PreparedStatement pstmt=con.prepareStatement("select regpassword from newuser where userid=?");
pstmt.setString(1, userid);
ResultSet rs=pstmt.executeQuery();
rs.next();
String p=rs.getString(1);
System.out.println(""+p);
return p;
}
그리고 stacktrace은 다음과 같습니다

DAO에서 'cancelaccount 다른 테이블에서 삭제 된 기능 mealdb도 있기 때문에 userid 필드는 primary key이고 newuser이고 foreign key은 mealdb입니다. 나는 그것을 열심히 들여다 보았다. 그러나 길을 발견 할 수 없었다. 고맙습니다.
그리고 감사합니다 @MaVRoSCy 귀하의 의문의 여지가있는 협력을 위해. – Mistu4u
