尝试将Web应用程序部署到我的计算机上安装的tomcat 7.0.35服务器实例时，我一直在收到一系列错误消息。该应用程序是使用eclipse在jsp中开发的。遇到异常javax.management.RuntimeOperationsException：异常调用方法检查
我收到第一条错误消息是：
FAIL - Encountered exception javax.management.RuntimeOperationsException: Exception invoking method check
上述错误消息来了以后我试图部署在Tomcat管理器应用程序的应用。
我有一个名为myapp.xml放置在工作空间中的应用程序的根文件夹的XML文件，并且其内容是：
<Context path="/myapp" docBase="d:\path\to\myapp"/>
我试图解决此错误消息的多种不同的方式，没有效果。过了一段时间，错误信息也开始出现。
最后，每隔几秒钟，控制台与大批量从它的继续重试新的错误消息的刷新，而这些错误消息包括以下内容：

这似乎是抛出一个空指针tomcat在tomcat文件夹中查找myapp.xml时发生错误。但似乎没有看到myapp.xml位于我的eclipse工作区中，位于我在tomcat管理器应用程序中提供的d：\ path \ to \ myapp url，如上所示。随着我不断尝试新事物，问题似乎越来越严重。
任何人都可以告诉我如何解决这一切，以便我可以在tomcat上部署我的应用程序？在此之前，我已经使用类似的方法在此服务器上部署了其他应用程序，没有任何问
