Question

我的应用程序最初是与Play一起开发的！框架版本2.3。

我正在尝试使用tomcat 7从war文件运行我的Web应用程序。

启动时，tomcat会记录下来：

我们已经可以看到很多警告，但我不明白它们的含义，某些目录不存在但是我已经安装了我的tomcat，而传统的apt-get install通常会安装我需要的一切。

问题在于我无法使其工作，我试图阻止tomcat然后将war文件移动到webapps目录并再次启动tomcat：这并没有启动我的应用程序..

然后我连接到tomcat web应用程序管理器，我的应用程序（confscheduler）可见并且没有运行：

我尝试了我的webapp名称右侧的开始按钮，但经过一段时间后，经理显示了此消息：失败 - 无法启动上下文路径/ confscheduler中的应用程序

FAIL - Application at context path /confscheduler could not be started

这是我的catalina.log的一部分，我们可以看到我的尝试：

.war文件是从我的Play中创建的！框架2.3使用play2war插件的应用程序，我真的按照项目的教程，但我不知道问题是来自war文件还是tomcat servlet。

如果你知道我做错了什么或者什么可以帮我解决这个问题，请告诉我。

感谢您的帮助

Tomcat无法从war文件
