MyEclipse报struts2的DTD出错

MyEclipse报struts2的DTD出错

刚刚新建个工程
给struts.xml加上DTD申明后，

XML code
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

居然报错说:
Referenced file contains error (http://struts.apache.org/dtds/struts-2.0.dtd)

缺少struts-config_2_0.dtd，在MyEclpse安装目录下myeclipse\eclipse\plugins\com.genuitec.eclipse.j2eedt.core_6.5.0.zmyeclipse650200806\catalog-dtd里面
