Transaction roll back exception in setRollbackOnly in stateless bean

Question

Hello All,
Im using WLS 5.1 SP9 on Win2k with Oracle 8.
Flow:
A stateless session bean with container-managed transaction uses
entity beans to insert records into 3 tables, vide:
Primary - CMP,
Secondary - BMP,
Tertiary - CMP
If validation fails on the data thats coming in, error messages are
sent back to the client and the transaction is set to roll back with
the folliwng stmt :
sessionContext.setRollbackOnly();
Now there are 2 problems :
1. Valid data is passed in: Though the operation seems to succeed from
the front end, there aren't any records inserted into the Primary
table. Secondary and Tertiary tables have the right data present in
them.
2. Invalid data is passed in: When the validation fails and the
transaction is set to rollback, the following exceptions are thrown :
Exception during commit of transaction: '1030642768442_27'
weblogic.transaction.RollbackException: Transaction TxC (26691678, xid
= 1030642768442_27, timeout = 60, txState = Rolledback, root = null
has been rolled back.Reason: Unknown
<!-- REST SNIPPED -->
I searched this ng for previous posts on this problema and indeed
found quite a few with the same problem. However, they referred to
this problem as a bug in the earlier service packs of Weblogic such as
4 and 5. I however use SP9, but still get the same problem.
Anybody have any ideas on these problems and possible solutions?
Thanks and regards,
Pavan

The problem seems to be related to the Adapter Engine but not sure about the exact reason. As per the last line of the log, either the channel reference was missing or there was some problem with the related service which could be viewed in visual admin. This could have occurred when the channel is initialized for the use. Restart helped because it may have restarted the related services.
