I think its not Pega calling J2EE as JEE. Its Oracle calling J2EE as JEE now (2 has been dropped from the name). So its fair to assume that JEE includes all those components that J2EE covers. Also check this link.
Thank you, I believe the link you provided is J2EE7 Specification, I did not see JNDI /JAAS /JDBC in that list. Some times saying JNDI /JDBC is not only part to J2EE is part of J2SE, not sure which one is correct.
