web.xml /WebTest/WebContent/WEB-INF line 41 XML Problem

原因：
在jsp2.0中,且2.4版的DTD验证中,taglib描述符,正确写法是放到描述符中。

解决办法：
1）将
改为，去除验证。

2）按规范，把taglib标签放进jsp-config标签中。如下：

  
    /tags/struts-bean
    /WEB-INF/lib/struts-bean.tld
  
  
    /tags/struts-html
    /WEB-INF/lib/struts-html.tld
  
  
    /tags/struts-logic
    /WEB-INF/lib/struts-logic.tld
