无法在 tomcat6 上启动 grails 战争
当我尝试部署 grails 应用程序时，我在 catalina.out 中收到此消息：
Feb 9, 2012 10:32:25 PM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart

运行 Grails 2.0、Tomcat 6、Ubuntu 10.04。我以前从未见过这样的事情，这是我正在做的事情/可以修复的事情还是Tomcat的设置方式？

Running Grails 2.0, Tomcat 6, Ubuntu 10.04. I haven't seen anything like this before, is this something I'm doing / can fix or something with how Tomcat is setup?

真正的错误将在日志目录中的另一个日志文件中。线程泄漏消息是一个问题，但在关闭时这是一个问题。您的启动失败是问题所在，除了
SEVERE: Context [/application]startup failed due to previousErrors之外，您所显示的内容根本没有描述它The real error will be in another log file in the logs directory. The thread leak messages are a concern, but that's an issue when shutting down. Your failure to startup is the problem and it's not described at all in what you've shown other than
SEVERE: Context [/application] startup failed due to previous errors您是否有机会运行后台线程插件？我见过 Tomcat 无法响应，因为该插件不放弃线程并阻止服务器正确关闭。
Are you running backgroundthread plugin by any chance? I have seen Tomcat fail to respond because of the plugin which does not give up the thread and prevents the server from shutting down correctly.
