I have:

and I got the following error:

Any idea?
Thanks a lot,

For the EJB, default transaction management type is CONTAINER and default transaction attribute for a business method is REQUIRED. So even though we did not specify transaction attributes in our bean class, defaults took over.

But for Bean manager Transaction as here.... Nothing is specified...???
Hence the Answer.

Welcome to the ranch. You may not be aware of the ranch Naming Policy. Please read it carefully and change your name accordingly. Thank you.

Nothing is specified...???

Then, what do you want to say other than what Shivreet Sekhon has already said ? What do you suggest ?
