[解决办法]
标签库 没有放进去 你看看
[解决办法]
查看web.xml文件中的
<taglib>
<taglib-uri> /WEB-INF/taglib/struts-bean </taglib-uri>
<taglib-location> /WEB-INF/taglib/struts-bean.tld </taglib-location>
</taglib>
解释：
<taglib-uri> 中的值为jsp中 <%@ taglib uri= "/WEB-INF/struts-bean.tld " prefix= "bean "%>
uri中的值
<taglib-location> 为标签tld文件的物理位置。
都查看下是否对上了。
再不行就得查tld文件对应的标签类，是否导入进来了。是否对上了
