    解决方法:

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

    另一篇描述比较透彻的分析如下:

      

    环境: win2003 tomcat 5.5 JDK1.6上 
    <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.4"
     xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >
    </web-app>
    jsp代码:

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

    1+2+3 = ${1+2+3} <br>   

    1+2+3 = <c:out value="6" /> <br>

    此时执行没有任何问题。

     1+2+3 = <c:out value="${1+2+3}" />执行时就会出现:

    According to TLD or attribute directive in tag file, attribute value does not accept any expressions

    昨天少了一个jsp,所以一直出现问题。

    代码

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

    写成   

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

    今天再试。发现JSTL1.1可以用。但是用JSTL1.0时,出现问题。

    就是把JSTL1.1的库放到/WEB-INF/lib/ 下。

    刚开始我是netbeans 5.5.1中的JSTL库拷贝出来发现可以用。后来用jstl1.1.2的库,也是可以用。

    总结:

    JSTL1.1的库 在JSP2.0(Servlet 2.4)及以后(推荐用JSTL1.1及以上)用:

    代码

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

    web.xml

    <?xml version="1.0" encoding="UTF-8"?>

    <web-app version="2.4"

             xmlns="http://java.sun.com/xml/ns/j2ee"

             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

             xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >

    </web-app>

    在 Servlet2.3及以前,

    代码

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

    比2.4以后版本少了jsp

    web.xml

    <?xml version="1.0" encoding="UTF-8"?>  

    <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">  

    <web-app>        

    </web-app>  

    在Servlet2.3中最好用JSTL1.0,如果用JSTL1.1,请加上

    <?xml version="1.0" encoding="UTF-8"?>  

    <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">  

    <web-app>       

        <taglib>  

            <taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>  

            <taglib-location>/WEB-INF/c.tld</taglib-location>  

        </taglib>  

    </web-app> 

    把tld目录下的c.tld拷贝到/WEB-INF?下。

     找到官方下载地址:

    http://jakarta.apache.org/site/downloads/downloads_taglibs.html

    选择 Standard 1.0 Taglib 和Standard 1.1 Taglib 可以下载jstl1.0和jstl1.1版本。

    According to TLD or attribute directive in tag file, attribute page does not accept any expressions

    说的是对应tag的属性不支持表达式传入。解决的办法是,在tld文件的相应tag的相应属性中加上rtexprvalue属性并设置为true,比如:

    <tag>

     <name>CustomTag</name>

     ……

     <attribute>

      <name>AttName</name>

      <rtexprvalue>true</rtexprvalue>

     </attribute>

    </tag>

    网上说这个和Tomcat的版本也有关系(5.x),我用的恰好是5.0.27,不过这个没有证实过。

    应用部署运行的时候出现JSP异常, 发生在使用JSTL库的时候: According to TLD or attribute directive in tag file, attribute value does not accept any expressions, 可能是因为使用了JSP2.0版本, 同时又没有使用JSTL core库的备用版本(RT库), 以下有两种处理方法:

    1. 修改web.xml.

    <web-app

    xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">

    改为2.3版本的

    <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

    <web-app>

    2. 使用JSTL core RT库

    JSTL core库的有两种taglib伪指令, 其中RT库即是依赖于JSP传统的请求时属性值, 而不是依赖于EL来实现(称为EL库.JSP2.0将支持EL)

    JSP中使用<%@ taglib uri=http://java.sun.com/jstl/core prefix="c"%>在2.3版本都可以,在2.4就不行了, 难道是版本不兼容吗?

    只要将

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

    改为

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

    就没有问题了
