An attempt to serialize the global session information 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: Session ID of the HTTP session
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 cannot be duplicated.

The following might be the causes for the error in serialization:

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

Action

Identify the cause of the error in serialization based on the contents of the stack trace that is output with the KDJE34412-E message ID to the Web servlet log, and take any of the following actions:

• Exclude the object in which the error occurred from the attribute of the HTTP session.
• Change the Web application and remove the cause of the error from the object that failed to be serialized.
