Makes sense. On our end we will probably start by creating a
javax.persistence.spi.PersistenceProvider facade to the current (non-
EJB3) Cayenne API. I need advice where and how we can plug this to
OpenEJB, and is this even possible at this point?
One caveat I can see at the moment is that OpenEJB 3 will/may
require JSE
5 or retroviewer or retrotranslator are used.
I haven't seen any official Sun statements on whether J2EE 1.5 should
work with JDK 1.4, but common sense tells me "no, it can't", cause it
relies on JDK 1.5 features. So is it even an issue with OpenEJB (or
Geronimo for that matter)? I mean if the spec says 1.5, why maintain
1.4 compatibility in the *new* releases?
In Cayenne this *is* an issue as it works as a standalone engine that
is not tied to a particular J2EE spec version. We addressed the need
to support JDK 1.5 and still provide a big subset (99%) of
functionality for 1.4 users by splitting the code in two subprojects,
with cayenne-1.5 dependent on cayenne-1.4:
