completed the thing answers question make "that" class implement java.io.serializable, here don't see of own classes involved. these libraries use , can't modify them. or it's tomcat trying use log4j
caused by: java.io.notserializableexception: org.apache.log4j.logger
one of classes trying deserialize (probably session attribute) contains field of type org.apache.log4j.logger. logger. logger fields should static, or @ least transient.
from stack trace seems exception occurs when serialized object being deserialized. means might have clean tomcat caches or internal session storage old data no longer there.
