通过手动加入Struts包来开发J2EE工程,可是结果却发现不能使用Struts的默认编辑器来打开Struts配置文件,双击打开Struts配置文件时,就出错,图片如下:

点击如下图的右侧"Deltails"按钮时,出现相关详细错误信息

org.eclipse.ui.PartInitException: Project newsjq 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.

看到"org.eclipse.ui.PartInitException: Project newsjq 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."这行错误提示,还以为默认编辑器被修改了,于是重新将它设成默认编辑器,结果还是不行.

后来仔细对比了一下手动加入Struts包的项目与[右键单击工程，选择MyEclipse-> add Struts capabilities]加入Struts的项目比较,发现他们在项目的文件里有一点点的差别,那就是在在项目下的.project文件里少了一行代码<nature>com.genuitec.eclipse.cross.easystruts.eclipse.easystrutsnature</nature>, 把这个加上去,就OK 了.

最后总结出修改办法,如下:

解决办法一:,在项目下的.project文件里添加一行代码<nature>com.genuitec.eclipse.cross.easystruts.eclipse.easystrutsnature</nature>,结果如下

</projectDescription>
......
</natures>
......
<nature>com.genuitec.eclipse.cross.easystruts.eclipse.easystrutsnature</nature>
</natures>
</projectDescription>
刷新工程就可以正常打开了

解决办法二:
右键单击工程，选择MyEclipse-> add Struts capabilities
