Question

当我尝试部署grails应用程序时，我在catalina.out中得到了这个：

Feb 9, 2012 10:32:25 PM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Feb 9, 2012 10:32:25 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/application] startup failed due to previous errors

SEVERE: A web application created a ThreadLocal with key of type [org.springframework.core.NamedThreadLocal] (value [Transaction synchronizations]) and a value of type [null] (value [null]) but failed to remove it when the web application was stopped.

运行Grails 2.0，Tomcat 6，Ubuntu 10.04。我之前没有见过这样的东西，这是我正在做什么/可以修复的东西或者Tomcat的设置方式？

Answer 1

真正的错误将出现在logs目录中的另一个日志文件中。线程泄漏消息是一个问题，但这是关闭时的问题。您的启动失败是问题，除了SEVERE: Context [/application] startup failed due to previous errors

之外，您所展示的内容完全没有描述

Answer 2

你是否有机会运行backgroundthread插件？我看到Tomcat没有响应，因为插件没有放弃线程并阻止服务器正常关闭。

无法在tomcat6上启动grails war
