看下面的配置，按文档配的话应该是Session的listioner在Application listener的前面，但运行时抛错说什么对象类型不对，现在如下把顺序换了下，运行正常了
<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>
