Tomcat can'；t从war文件启动我的web应用程序

我的应用程序最初是用Play开发的！框架版本2.3

我正在尝试使用Tomcat7从war文件运行我的web应用程序

启动时，tomcat会记录以下内容：

.war文件是根据我的剧本创建的！Framework2.3应用程序通过使用该插件，我确实遵循了该项目的教程，但我不知道问题是来自war文件还是TomcatServlet

如果你知道我做错了什么，或者什么能帮助我克服这个问题，请告诉我

感谢您的帮助

除此之外还有其他错误吗？由于以前的错误，Message

启动失败

意味着在显示该错误时该错误已经发生。@Gary我添加了启动日志，该日志似乎有很多警告，并尝试首次启动我的应用，这可能是前面的错误，因为这是在我尝试之前发生的唯一其他事情。有时，一年中我会遇到1、2次动态取消部署/部署问题。也许单身汉会产生冲突，也许循环引用，也许加载器无法在两者之间说话。通常JDBC驱动程序、H2或ehacache会给出问题。重新加载整个Tomcat会有帮助吗？现实生活中的一个附加问题：新的部署需要新版本的框架库，而旧的框架库没有相同的结构仍然存在于容器中。@JacekCz你的意思是我应该尝试重新加载Tomcat吗？我已经用

服务tomcat7 stop/start

试过了。
