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
