严重: Error filterStart

2011-12-16 0:48:00 org.apache.catalina.core.StandardContext start

严重: Context [/Bank_Report] startup failed due to previous errors

2011-12-16 0:48:00 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap

严重: The web application [/Bank_Report] created a ThreadLocal with key of type [com.opensymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@1bfbe18]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@1593225]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
