The ejbcertificate site states that �The enterprise bean cannot make use of the Java Swing API� while, Mikalai Zaikin's SCBCD Study Guide (JavaRanch SCBCD Links) states � An enterprise Bean must not use the AWT functionality to attempt to output information to a display, or to input information from a keyboard. � and does not comment on Java Swing.
Which source is correct or are they both correct?
Thanks for the clarification.

Enterprise beans are written to operate inside of an EJB container, so I don't think they could ever get access to the resources that Swing or AWT use. EJB's are not concerned about user interfaces.
Have a look at the "Model-View-Controller" design pattern and at tiered architecture.
Not sure why you would want to mix the persistence layer with the presentation layers [if you could!]. I think if you designed a system with only one architectural tier, it would end in tears!
