Hi Kathy -
You said that CMT demarcated beans CANNOT use UserTransaction. The specs 10.5.9.1 (CreateException in the Entity bean chapter) says that "client may determine the transaction status using the UserTransaction interface". This is for 2.0 entity beans which definitely can only use CMT.
Can you please explain to me this difference ?
Thanks and regards, Sudd

The client can use userTransaction but not the bean using CMT.
Let us say that a client initiated a Tx using UserTranaction interface by invoking begin. It then invokes some CMT bean method. Suppose an exception occurs in some method, the bean may invoke setRollBackOnly(). The client can get to know the status using UserTransaction.
