Java EE Question

Hi all,

Couldn't see a Java EE forum so thought i would post it in here.

I am stuck on a practice paper question:

Explain the roles of the logical tiers found in the Java Enterprise Edition (JavaEE) 6 architecture

There seems to be nothing at all online whatsoever on this, i have been searching thoroughly. I wonder if anyone on here knows anything about it or could provide a link.

Exam is in a few days so any help is hugely appreciated.

I have just seen there is a Java EE forum so please feel free to move moderators.
