An attempt to serialize the attribute information has failed. (J2EE application = aa....aa, context root = bb....bb, HTTP session ID = cc....cc, attribute name = dd....dd, invalid class = ee....ee)

aa....aa: J2EE application name
bb....bb: Context root name
cc....cc: HTTP session ID
dd....dd: Name of the attribute that failed to be serialized
ee....ee: Class name of the object that failed to be serialized

Description

An attempt to serialize the attribute information of the HTTP session has failed. The information of this HTTP session will not be replicated in the database.

Note that if the HTTP session is invalid during output of this message, null is output to the HTTP session ID (cc....cc).

Action

Determine the cause of the failure in serialization based on the contents of the stack trace output with the message ID KDJE34319-E in the Web servlet log, and then take either of the following actions:

• Remove the erroneous object from the attributes of the HTTP session.
• Change the Web application, and then remove the cause of the error from the object that failed to be serialized.

Take action based on the following causes of the failure in serialization:

• The object referenced from the object of the attribute that failed to be serialized was not from a serializable class.
• The writeObject(java.io.ObjectOutputStream out) method is implemented, and an exception occurred during serialization.
