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

<servlet-mapping>
<servlet-name> dispatcher </servlet-name>
<url-pattern> /dispatcher </url-pattern>

<taglib> （这里为什么个有大红叉)
<taglib-uri> /mytaglib </taglib-uri>
<taglib-location> /web-inf/mytaglib.tld </taglib-location>
</taglib>

</web-app>
但下面这些为什么对的:

<?xml version="1.0" encoding="iso-8859-1"?>

<!doctype web-app public
'-//sun microsystems, inc.//dtd web application 2.3//en'
'http://java.sun.com/j2ee/dtds/web-app_2_3.dtd'> //不一样的

<taglib>
<taglib-uri> /mytaglib </taglib-uri>
<taglib-location> /web-inf/mytaglib.tld </taglib-location>
</taglib>

</web-app>
这两个只是我标记的了地方不一样,问题在哪!是标记那有问题?但上面一个我是在myeclispe中自己生成的,只是加个 <taglib> 就不对,web中有 <taglib> 这个标签的啊!

web-app version="2.4"

下边的是2.3

如2楼所述,xml 的 version 不一样, validator rule 也不一样

2.4和2.3都应该对 <taglib> 支持吧!怎么会出错啊?请略详解!

我已经试过了,确实是2.4不支持 <taglib> 标签

下面是在myeclipse中的报错信息,楼主可以看一下:

那在2.4版中是不有没办法用 <tablib> 了,有什么办法可用吗?

发表于：2008-01-10 13:52:246楼得分:0

2.4中使用 <taglib> 的方法:

在 <taglib> 外面加上 <jsp-config>

2.3中可以直接写:

xml code


  <taglib> 
      <taglib-uri> /mytaglib </taglib-uri> 
      <taglib-location> /web-inf/mytaglib.tld </taglib-location> 
  </taglib>

2.4中要写成:

xml code


  <jsp-config>
      <taglib> 
          <taglib-uri> /mytaglib </taglib-uri> 
          <taglib-location> /web-inf/mytaglib.tld </taglib-location> 
      </taglib>
  </jsp-config>
