myeclipse struts config editor 出错

用MyEclipse struts config editor 编辑器编辑Struts的配置文件错误:org.eclipse.ui.PartInitException: Project fuNan_eAdmin is not configured as a MyEclipse Web-Struts Project. Therefore the MyEclipse Struts Editor may not be used with struts-action.xml. The default XML Editor has been used to open the file instead.

解决方法：
方法1.在项目上点击右键，选择“myeclipe”下的“add struts capabilities”即可解决

方法2.若方法一不能解决，则找到项目所在目录，找到.project文件。在<natures>节点中添加<nature>com.genuitec.eclipse.cross.easystruts.eclipse.easystrutsnature</nature>，重新打开项目问题即可解决。
