I
suspect that Java EE 5 is okay to use, the basis for my logic being that my
SCEA certificate (issued last September, while Java EE 5 was in beta) states that it is for "Java Platform Enterprise Edition Technology", which is how Sun itself describes the latest standard. Plus, this isn't a new thing, but rather a renaming of J2EE to remove the confusion of the '2' in the Java technologies.
(For reference, I used J2EE 1.4, so I'm by no means the best authority. As stated above, an email probably would clear this up.)
