Question

尝试将Web应用程序部署到计算机上安装的tomcat 7.0.35服务器实例时，我收到了一系列错误消息。该应用程序是使用eclipse在jsp中开发的。

我收到的第一条错误消息是：

FAIL - Encountered exception javax.management.RuntimeOperationsException: Exception invoking method check

在我尝试在tomcat管理器应用程序中部署应用程序之后出现上述错误消息。

我有一个名为myapp.xml的xml文件放在工作区中应用程序的根文件夹中，其内容为：

<Context path="/myapp" docBase="d:\path\to\myapp"/>

我尝试以多种不同的方式解决此错误消息，但没有任何效果。一段时间后，也会出现错误消息。

最后，每隔几秒钟，控制台就会重新刷新一大堆新的错误消息并继续重试，这些错误消息包括以下内容：

当tomcat在tomcat文件夹中查找myapp.xml时，似乎抛出了空指针错误。但似乎没有看到myapp.xml位于我的eclipse工作空间中，我在tomcat管理器应用程序中给出的d：\ path \ to \ myapp url，如上所示。随着我不断尝试新事物，似乎问题越来越严重。

任何人都可以告诉我如何修复所有这些，以便我可以在tomcat上部署我的应用程序吗？我之前使用类似的方法在此服务器上部署了其他应用程序而没有任何问题。

我通过卸载然后重新安装eclipse和tomcat来解决这个错误。

遇到异常javax.management.RuntimeOperationsException：异常调用方法检查
