Java EE 5 on NetWeaver 7.0

Hi everyone

Please could someone clarify whether NetWeaver 7.0 can support Java EE 5?

From what I've read, I see that it supports J2EE 1.4 - but there's functionality in 1.5 that I need to use. Is there an upgrade available for NW 7.0 to support Java EE 5? If not, is one planned for the future?

One option would be to upgrade to NW 7.1, but I don't think Portal is released yet (which is a crucial part of our system).

Any ideas?

Thanks in advance!
