Don’t use lazy loading if your data will
be transferred (via rmi,…). And moving to 2.x will not help, I don’t
think that it can help. And also it is not good for performance. Even if in new releases lazy loading
will support Remote interface for RMI, you will lose much time on transfers. Best, From: Khanna, Vijay
(GE, Corporate, consultant) [mailto:[EMAIL PROTECTED] 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.. 10:14:16,764 INFO [STDOUT] java.io.NotSerializableException:
