jsp初学小问题

如题就是EL表达式不知道为什么接收不到值，request可以
jsp代码：

<table align="center" border=1>
  <tr>
      <td>名称 </td> <td>城市 </td> <td>票价 </td>
  </tr>
  <tr>
      <td>${name[0]} <%=request.getAttribute("city") %> </td> <td>${city[0]} </td> <td>${price[0]} </td>
  </tr>
  <tr>
      <td>${name[1]} </td> <td>${city[1]} </td> <td>${price[1]} </td>
  </tr>
  <tr>
      <td>${name[2]} </td> <td>${city[2]} </td> <td>${price[2]} </td>
  </tr>
</table>

java代码：

package javabean;

import java.io.IOException;
import java.util.ArrayList;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class SetAccess extends HttpServlet {

/**
