Please, read the original message carefully. You are not within a transaction. Transaction Isolation Level should not have anything to do with this problem. I know how I would solve this problem outside EJB. I would use a time stamp for example. Again, we are talking about detecting if the data has changed after first transaction completed and the second began. In between a few other transactions could have gone in and changed the data.

Hi
PL read isolation levels for CMP. It all depends upon the isolation level
you set
Thanks

Subject: Compilation problem.
Hello all,
I am new to EJB. I am using Sun's J2ee implementation server, while
trying to deploy an entitiy bean, i am getting this following error.
java.rmo.ServerException : RemoteException occurred in server thread;
nested exception is:
java.rmi.RemoteException : Error processing ejb jar: Compilation failed
The server is able to deploy the bean, but while generating the wrapper
code it throws this RemoteException.
help needed to solve this problem.
tia,
vishwa
