配置Struts2 xml Referenced file contains errors (http://struts.apache.org/dtds/struts-2.0.dtd). For m

换了myeclipse版本出现这样错误：Referenced file contains errors (http://struts.apache.org/dtds/struts-2.0.dtd). For more information, right click on the

 message in the Problems View and select "Show Details..."

解决办法： 在myeclipse9.0，      [MyEclipse]-[Files-Editors]-[XML]-[XML Catalog]    查找到  “-//Apache Software Foundation//DTD Struts Configuration 2.1//EN ”   和

“-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN ” 

只需将struts.xml文件  “-//Apache Software Foundation//DTD Struts Configuration 2.0//EN ”   2.0修改为对应的 2.1或是2.1.7   ctrl+s即可
