Hi there,
I'm using a stateless EJB3 bean to manage my pojo.
My question is: in a J2EE web application, which exceptions should be handled in this kind of bean?

Thanks in advance

You can let the container rollback the transaction in case of exceptions, so your answer can be just "None". :-)

I'm new with EJB3 and Enterprise beans, I need some more details. For example, let's say I've got a method which is available on the interface and it returns all my users from the database. The signature hasn't any throws declaration, what would happen if somehing goes wrong??

Thanks again
