看下面的配置，按文檔配的話應該是Session的listioner在Application listener的前面，但運行時拋錯說什么對象類型不對，現在如下把順序換了下，運行正常了
<filter>
<filter-name>container</filter-name>
<filter-class>com.opensymphony.webwork.lifecycle.RequestLifecycleFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>container</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
<listener>
<listener-class>com.opensymphony.webwork.lifecycle.ApplicationLifecycleListener</listener-class>
</listener>
<listener>
<listener-class>com.opensymphony.webwork.lifecycle.SessionLifecycleListener</listener-class>
</listener>
