無法解決此錯誤 - NotSerializableException？

Question

java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException 

爲什麼在啓動我的服務器Tomcat 6.0時出現此錯誤？

Context Initialized 

Answer 1

<Context antiJARLocking="true" antiResourceLocking="true" reloadable="true" path="/janus-atreya-emr"> 
    <Manager className="org.apache.catalina.session.PersistentManager" saveOnRestart="false"/> 
</Context> 

我可以改變這種情況下文件：
