一般这种错误是发送id的时候，servlet接收不到。

import java.io.IOException;  
import javax.servlet.ServletException;  
import javax.servlet.annotation.WebServlet;  
import javax.servlet.http.HttpServlet;  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;

import edu.jmi.emp.dao.EmpDao;

/\*\*  
 \* Servlet implementation class deleteServlet  
 \*/  
@WebServlet("/deleteServlet")  
public class deleteServlet extends HttpServlet \{  
    private static final long serialVersionUID = 1L;  
         
    /\*\*  
     \* @see HttpServlet\#HttpServlet()  
     \*/  
    public deleteServlet() \{  
        super();  
        // TODO Auto-generated constructor stub  
    \}

/\*\*  
     \* @see HttpServlet\#doGet(HttpServletRequest request, HttpServletResponse response)  
     \*/  
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException \{  
        // TODO Auto-generated method stub  
        response.getWriter().append("Served at: ").append(request.getContextPath());  
        doPost(request, response);  
    \}

/\*\*  
     \* @see HttpServlet\#doPost(HttpServletRequest request, HttpServletResponse response)  
     \*/  
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException \{  
        // TODO Auto-generated method stub  
        request.setCharacterEncoding("utf-8");  
        int id=Integer.parseInt(request.getParameter("id"));  
        EmpDao empDao=new EmpDao();  
        boolean b=empDao.deleteEmp(id);  
        System.out.println(id);  
        if(b==true) \{  
            request.getRequestDispatcher("MainServlet").forward(request, response);  
        \}else \{  
            response.sendRedirect("index.jsp");  
        \}
