急！！！急！！！J2EE的有关问题
我用Myeclipse做了一个简单的登录和注册页面，但总是出现以下问题：
严重: Exception starting filter struts2

严重: The web application [/sshtext] created a ThreadLocal with key of type [com.opensymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@147027a]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@f3d4c3]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.

严重: The web application [/sshtext] created a ThreadLocal with key of type [com.opensymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@157ace]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@317bdd]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
log4j:ERROR LogMananger.repositorySelector was null likely due to error in class reloading, using NOPLoggerRepository.
[解决办法]
项目clean，重新部署下试试。
