我在两台不同的机器上使用完全相同的方法安装了Tomcat。 两者都使用这里find的Windows服务安装程序
我生成一个WAR文件做mvn clean install -X 。 然后，我将WAR文件复制到其他两台Windows计算机上，并尝试通过Web App Manager和WAR文件放在\ webapps文件夹中进行部署。 我可以在一台机器上启动应用程序，但不能启动其他应用程序。 再一次，Tomcat的安装是完全一样的，我已经尝试重新安装Tomcat的应用程序没有启动的机器，但仍然无法启动我的应用程序。
这里是应用程序工作的机器上的tomcat7-stdout.log：
2017-07-21 11:58:28 Commons Daemon procrun stdout initialized
这里是应用程序不工作的机器上的tomcat7-stdout.log。 有一个NullPointerExceptionexception显示，有些东西是失踪，但我不知道是什么。 Tomcat 7.0 \ libs文件夹中的依赖关系在两台机器上是相同的。

任何意见，为什么完全相同的Tomcat安装和WAR文件在一台机器上工作，而不是其他的将不胜感激！
