嗨我所面临的问题，同时使用forEach迭代我给完整的代码，请告诉我这是什么错误。forEach标签有问题

的index.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" 
    pageEncoding="ISO-8859-1"%>

Servlet的代码：

package com.foreach; 

import java.io.IOException; 

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

/** 
* Servlet implementation class foreachservlet 
*/ 
public class foreachservlet extends HttpServlet { 
    private static final long serialVersionUID = 1L; 

    /** 
    * @see HttpServlet#HttpServlet() 
    */ 
    public foreachservlet() { 
     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 

     try{ 
      System.out.println("Getting inside get method--"); 
      String[] movieList={"Isquia","3 idiots","Kurbaan","Jab we met"}; 
      request.setAttribute("movieList",movieList); 

      System.out.println("After setting attribute"); 
      RequestDispatcher dispatcher=request.getRequestDispatcher("/pages/welcome.jsp"); 
      dispatcher.forward(request, response); 

       System.out.println("Last line--"); 

     }catch(Exception e){ 
      e.printStackTrace(); 
     } 


    } 

    /** 
    * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) 
    */ 
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
     // TODO Auto-generated method stub 
    } 

}

jsp代码：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> 
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %> 
<HTML> 
<HEAD><TITLE>Movie Collections</TITLE> 
</HEAD> 
<BODY> 
    <strong>Movie list</strong><br></br> 
    <TABLE BORDER=5 ALIGN="CENTER"> 
    <c:forEach var="movie" items="${movieList}"> 
     <tr> 
     <td>${movie}</td> 
     </tr> 
    </c:forEach> 
    </TABLE> 
</BODY></HTML>

我收到以下错误，我无法理解。

welcome.jsp:9:24: Static attribute must be a String literal, its illegal to specify an expression. 
<c:forEach var="movie" items="${movieList}"> 
         ^---^ 
welcome.jsp:9:24: Static attribute must be a String literal, its illegal to specify an expression. 
<c:forEach var="movie" items="${movieList}"> 
         ^---^

请帮忙。谢谢

我认为这是因为你的taglib声明中的URI不正确。它应该是

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

，而不是

<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>

您正在使用的一个是旧的，预JSP-2.0库，它不支持运行时表达式（表达中传递作为原始字符串并由标签本身评估，而不是JSP引擎）。

编辑：看起来它是你与Expression Language in JSP not working

在另一个问题中，他最初在模板文本中遇到了EL问题。 – BalusC 2010-02-07 13:24:18

非常感谢先生。问题仅在于标签库。 – user262577 2010-02-07 14:08:25

很高兴帮助你。请不要忘记标记他的答案**接受**通过点击左边的大白色复选标记:)这就是它应该如何在这里工作在Stackoverflow：http://stackoverflow.com/faq – BalusC 2010-02-08 02:33:31

同样的问题，你可以试试：

<c:forEach items="${movieList}" varStatus="i"> 
    <td>${movieList[i.index]}</td> 
</c:forEach>

请加入这一行：

<%@ taglib uri='http://java.sun.com/**jsp**/jstl/core' prefix='c'%>

相反的：

<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>

其实JSTL - 只是一套自定义标签，不能单独使用。如果你不使用任何MVC框架，那么你需要自己做一些修改。如果您正在使用Spring MVC的则包括JSTL为：

<%@taglib prefix="c" uri="http://java.sun.com/jstl/**core_rt**"%>

如果不使用core_rt那么它会抛出错误。
