j2ee5.0使用jtsl报错
框架是struts2.1.8，使用嵌入式jetty6.1.5启动或者tomcat6.0.18启动都报同样的问题：（细节有区别）

jetty报错如下：

网上的办法都试过了，比如拷贝myeclipse路径下的4个jar到tomcat下等，涛声依旧，求达人帮忙看看，本人qq465089135.坐等。


[解决办法]
请使用servlet2.4格式的web.xml头：
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" 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">

然后在web.xml中去除对taglib的声明再试试看

如果不是这个问题你还是贴一下web.xml出来给大家分析一下，至少把引用到uri的那部分贴出来看看
[解决办法]
由于JSTL1.0和JSTL1.1的声明语句不一样。

JSTL 1.0 的声明是：
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core " %>

JSTL1.1 的声明是：
<%@ taglib prefix="c" uri=http://java.sun.com/jsp/jstl/core %>

如果你使用的JSTL库和你在JSP中的声明不一致。就会报上面提到的Exception。

另外，要注意的是：Tomcat是先引用"TOMCAT_HOME/shared/lib"下面的库，再引用web项目下面的"WEB-INF/lib'的库。

还有就是，jBuilder自带库中的JSTL有两个配置，一个是"JSTL"(1.0)，一个是"JSTL1.1"(1.1)，注意在做项目的时候别引用错了。

还有一个技巧是：如何判断JSTL的两个库文件(standar.jar和jstl.jar)的版本？展开jar文件在"META-INF"目录下的MANIFEST.MF文件，其中"Specification-Version"指名的就是版本号。

[解决办法]
从网上搜了一下，相同的说法是：一个就是JSTL的版本问题（1.0与1.1），是否不一致。还有就是检查虚拟目录下WEB-INF目录下的lib文件夹(如果同有lib文件夹，后动创建一个）中是否有jstl.jar和standard.jar两个jar包，如果没有则把它们复制到lib下面。

都试了，不过报错依旧……后来又找了一下加上自己的乱搞，按照上面的改过之后，大体有两种解决方法：

第一种就是在Eclipse的工程中导入JSTL1.1后，下载JSTL1.1 http://jakarta.apache.org/taglibs/index.html
然后解压,把*.jar和*.tld放到/WEB-INF/lib目录下。也就是将所有的jakarta-taglibs-standard-current.zip（JSTL的类库）中的.jar和.tlb放到WEB-INF目录下的lib文件夹中，JSP文件中导入<%@ taglib prefix="c" uri="/WEB-INF/lib/c.tld" %>，经试验是可以的。

第二种是修改web.xml，加上下面的语句：

<jsp-config>

<taglib>

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

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

</taglib>

<taglib>

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

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

</taglib>

<taglib>

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

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

</taglib>

<taglib>

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

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

</taglib>

</jsp-config>

JSP中导入<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>。应该就可以了……

推荐第二种^_^！
[解决办法]

很明显jstl的uri不对，看你用的哪个版本，不同版本还不一样，上面两位说的应该很明显了
[解决办法]
web.xml头部有问题吧,
顶#1楼

我不作回答了,上面的方法搞不定我也是白说.
