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. =20 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. Thanks in advance, =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= To unsubscribe, send email to [email protected] and include in the = body of the message "signoff EJB-INTEREST".
