打开struts-config.xml 报错 解决办法Could not open the editor

错误信息:Could not open the editor: Project XXX is not configured as a MyEclipse Web-Struts Project. Therefore the MyEclipse Struts Editor may not be used with struts-config.xml. The default XML Editor has been used to open the file instead.

解决方法：找到你工程下的.project文件，打开，在<natures>节点下面加上

<nature>com.genuitec.eclipse.cross.easystruts.eclipse.easystrutsnature</nature>

就可以了。
