Betreff: ***SPAM*** EJB questions

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.


Thanks in advance,
