Hi, I am new to EJB.I use stateless sessionbean. I have the below questions.Could anyone give me your suggestions / comments? 1.My ejb method calls a Data Access Object class's method. In my Data Access Object's class method can I catch Exception? Is this ok? Yes it is. You might want to hide the underlying SQL exception , potentially can be DB vendor specifics, and raise only say DataAccessException to the caller. 2. My ejb method performs single row insert into database.Is it ok if i set the transaction attribute to NotSupported? If you are using Transactional Data Source, you need to have a transaction for every DB operation.
