这个问题怎么解决 ？要导入哪些包？

我现在导入了

memcached-session-manager-1.4.0.jar

memcached-2.5.jar

kryo-1.03.jar

minlog-1.2.jar

reflectasm-0.9.jar

asm-3.2.jar

kryo-serializers-0.8.jar

msm-kryo-serializer-1.4.0.jar

javolution-5.4.3.1.jar

msm-javolution-serializer-1.4.0.jar

xstream-1.3.1.jar

xpp3_min-1.1.3.4.O.jar

msm-xstream-serializer-1.4.0.jar

都放到了 tomcat lib中

######问题解决了吗？######cookie 可保存少量信息，如果有更多的信息可用memcached集中保存。 这样可以屏蔽调session管理
