解决方案 »

  1.   

    attribute test does not accept any expressions 
      

  2.   

    jstl_core.jsp(19,4)页面上少写了些东西,或者你写的表示与jar包定义的tld不相符
      

  3.   

    这是我写的程序：jstl_el.jsp<%@ page language="java" contentType="text/html; charset=GBK"%>
    <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"%><html>
    <head>
    <title>测试EL表达式</title>
    </head>
    <body>
    用户名：<li>${people.username}</li><br>
    密码:<li>${people.password}</li><br>
    用户名：<li>${people.username}</li><br>
    <c:set value="123" var="temp"/>
    <c:out value="${people.password}"/>
    ${temp} 
    </body>
    </html>
      

  4.   

    <c:out value="${people.password}"/> 标签不支持嵌套，你把它换下试试
      

  5.   

      明显是jsp页面报错啊
      看看是否不支持标签啊，或者缺少标签对啊
      
      

  6.   

    加上<%@ page isELIgnored="false" %>这个试试 如果不行那就是你的jstl那个标签版本不对 或者是路径不对 而且你换换<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>这样 试试 如果不行的话可以去http://www.blogjava.net/jiafang83/archive/2008/11/07/239284.html这个网站上看看
      

  7.   

    我测试了一下你的 把那个换成<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>这个就ok了
      

  8.   

    <c:out value="${people.password}"/> 
    这个标签不支持表达式
      

  9.   

    <tag>
        <name>out</name>
        <tag-class>org.apache.taglibs.standard.tag.el.core.OutTag</tag-class>
        <body-content>JSP</body-content>
        <description>
    Like &lt;%= ... &gt;, but for expressions.
        </description>
        <attribute>
            <name>value</name>
            <required>true</required>
            <rtexprvalue>false</rtexprvalue>
        </attribute>
        <attribute>
            <name>default</name>
            <required>false</required>
            <rtexprvalue>false</rtexprvalue>
        </attribute>
        <attribute>
            <name>escapeXml</name>
            <required>false</required>
            <rtexprvalue>false</rtexprvalue>
        </attribute>
      </tag>
    应该用这个导入这个taglib
    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
      

  10.   

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

  11.   


    似乎又是uri缺了个jsp，记得好像你昨天回过一个同样得帖子，哈哈哈哈
