Hi Ramya,
try changing the Isolation level to READ UnCommitted. I think it should
work. Coz if Isolation level is other than this then Session bean is
locking the record while reading, so Entity bean fails to update the same
record.
or if u can not change the isolation level do following:
1. read method of session bean be in separate transaction.
2. Make sure that for update method of entity bean Transaction Attribute be
Required_New. in new transaction if any lock is there of previous
transaction will be
released.
Thanks,
Rajdeep
