嘗試將Web應用程序部署到我的計算機上安裝的tomcat 7.0.35服務器實例時，我一直在收到一系列錯誤消息。該應用程序是使用eclipse在jsp中開發的。遇到異常javax.management.RuntimeOperationsException：異常調用方法檢查
我收到第一條錯誤消息是：
FAIL - Encountered exception javax.management.RuntimeOperationsException: Exception invoking method check
上述錯誤消息來了以後我試圖部署在Tomcat管理器應用程序的應用。
我有一個名爲myapp.xml放置在工作空間中的應用程序的根文件夾的XML文件，並且其內容是：
<Context path="/myapp" docBase="d:\path\to\myapp"/>
我試圖解決此錯誤消息的多種不同的方式，沒有效果。過了一段時間，錯誤信息也開始出現。
最後，每隔幾秒鐘，控制檯與大批量從它的繼續重試新的錯誤消息的刷新，而這些錯誤消息包括以下內容：

這似乎是拋出一個空指針tomcat在tomcat文件夾中查找myapp.xml時發生錯誤。但似乎沒有看到myapp.xml位於我的eclipse工作區中，位於我在tomcat管理器應用程序中提供的d：\ path \ to \ myapp url，如上所示。隨着我不斷嘗試新事物，問題似乎越來越嚴重。
任何人都可以告訴我如何解決這一切，以便我可以在tomcat上部署我的應用程序？在此之前，我已經使用類似的方法在此服務器上部署了其他應用程序，沒有任何問
