Answer 1

关键点是，web.xml 中各种元素的出现是有先后顺序的。

Answer 2

目錄下有這個嗎？
WEB-INF/struts-logic.tld

Answer 3

呵呵，我把你复制到web.xml里面，
就是编辑器在<taglib>这里打了个红叉，提示：
invalid content was found starting with element 'taglib'.

Answer 4

目錄下有這個嗎？
WEB-INF/struts-logic.tld
-------------------------
有的啊！

Answer 5

你把我的完全复制进去当然有错，
<taglib-location>/WEB-INF/tlds/struts-tiles.tld</taglib-location>
这里面的路径要换成你的

Answer 6

<taglib>
    <taglib-uri>/WEB-INF/struts-bean</taglib-uri>
    <taglib-location>/WEB-INF/struts-bean.tld</taglib-location>
  </taglib>
  <taglib>
    <taglib-uri>/WEB-INF/struts-html</taglib-uri>
    <taglib-location>/WEB-INF/struts-html.tld</taglib-location>
