什么原因导致Tomcat出现这种错误？

SEVERE: Exception loading sessions from persistent storage
java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException:

在Tomcat 7上部署我的webApplication时,我将获得下面的控制台输出.重新启动服务器两次或三次后,它可以正常工作.

我正在使用JSF,Tomcat和businesslogic部分的RMI连接(在这里应该没关系？)

@ViewScoped托管bean中的@EJB导致java.io.NotSerializableException - 这里我读到了序列化.但是在这种情况下,客户端状态保存被激活,这在我的webApp中并非如此(就我的web.xml告诉我而言).那么我的视图编译ManagedBeans的序列化是必要的还是另一个失败？

这是我的启动控制台输出(Sry中的德语部分):

我在@ViewScoped托管bean中读过@EJB会导致java.io.NotSerializableException,但是我的状态保存设置是server.

这是我有的:
