This is a fundamental question of paramount importance to EJB 3.0 entity bean
development. EJB 3.0 keeps it simple and loads everything. You can take a
different tack and lazy load everything for maximum performance.
When you get an exception such as yours, you can analyze the situation. If tha
That's great! I got it. Thank you so much.

session / datasource and cannot retrieve the files. You might consider writing
a getFiles method in your stateless bean and call that inste

First, I use JSF session bean to call local interface of dao stateless bean to
get a folder instance using a EJBQL, then call the folder.getFiles() in the JSF
session bean to try to get all files under the folder. If I set
