配置tomcat应用程序的上下文路径

我'm trying to change the context path of a tomcat application. I'已经阅读this问题，并尝试按照接受的答案中所述添加 root.xml 文件：

在$ CATALINA_BASE / conf / [enginename] / [hostname] /中添加root.xml文件，并将其添加为：<Context
的docBase = “/选择/ mywebapps / <yourApp>”
路径=“”
重新加载=“真”
/>
有关更多详细信息，您可以使用Apache上下文配置链接：http：//tomcat.apache.org/tomcat-7.0-doc/config/context.html

但这对我不起作用 . 我在这里错过了什么？

我的webapp的路径： C:\apache-tomcat\webapps\activiti-webapp-explorer2-5.18.0

我的 root.xml 文件的路径： C:\apache-tomcat\conf\Catalina\localhost\root.xml

另外，创建root.xml文件仍然是为webapp配置上下文路径的首选方法吗？如果有一种模式“正确”的方式，我想知道它 .

EDIT:

我忘了提到两件重要的事情 . 第一个是我通过导航到 localhost:8080/activiti-webapp-explorer2-5.18.0 来访问我的应用程序

EDIT2:

这是我的C：\ apache-tomcat \ conf \ Catalina \ localhost \ root.xml：

<Context path="activiti-explorer-2" docBase="C:\apache-tomcat\webapps\activiti-webapp-explorer2-5.18.0" reloadable="true">

这是我的C：\ apache-tomcat \ webapps \ activiti-webapp-explorer2-5.18.0 \ WEB-INF \ web.xml：
