解决 Implementation of project facet jst.web.jstl could not be found. Functionality will be limited.

在开启MyEclipse时遇到的问题:

Description Resource    Path    Location    Type
Implementation of version 2.0 of project facet jst.jaxrs could not be found. Functionality will be limited. HNUST       Unknown Faceted Project Problem

Description Resource    Path    Location    Type
Implementation of project facet jst.web.jstl could not be found. Functionality will be limited.         Unknown Faceted Project Problem

此类问题一般发生在你用你的IDE导入别人的项目, 解决方案:

1. 打开你的工作空间, 找到.settings文件夹中的org.eclipse.wst.common.project.facet.core.xml
2. 删掉<faceted-project>标签下的所有内容

最后, Demo就跑起来了!

因为折腾了半天, 所以把它写下来进行记录!
