如下代码编译时总出现不能识别RequestDisPatcher的错误，请大家帮忙看看！
package mypack;

import java.util.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class DispatcherServlet extends HttpServlet
{
  private String target = "/hello.jsp";

  public void init(ServletConfig config)
    throws ServletException
  {
    super.init(config);
  }

  public void doGet(HttpServletRequest request,HttpServletResponse response)
    throws ServletException,IOException
  {
    doPost(request,response);
  }

  public void doPost(HttpServletRequest request,HttpServletResponse response)
    throws ServletException,IOException
  {
    String username = request.getParameter("username");
    String password = request.getParameter("password");

    request.setAttribute("USER",username);
    request.setAttribute("PASSWORD",password);

    ServletContext context = getServletContext();

    System.out.println("Redirecting to " + target);

    RequestDisPatcher dispatcher = context.getRequestDispatcher(target);
    dispatcher.forward(request,response);
  }

  public void destroy()
  {

  }

}
