java.io.NotSerializableException: com.ibatis.db.sqlmap.LazyLoadList

[Khanna, Vijay \(GE, Corporate, consultant\)]

Hello,

 

We are using Ibatis 1.x along with JBoss cache. Now when the application is run in clustered environment and the Cache & session replication happens, we are getting an error from Ibatis. "java.io.NotSerializableException: com.ibatis.db.sqlmap.LazyLoadList" . I checked within the application code to find if we are using any instance of java.lang.Object, but could not find any...

 

From the stacktrace below, it seems that and instance of 'java.lang.Object' is present in the list and thats where the problem is...

 

I checked Ibatis 2.x and noticed this problem does not occur. But due to some reasons, we do not wish to move to 2.x but would like a solution for this. Help from the Ibatis's Gurus appreciated !

 

Heres the detailed stack..
