Hi All,
I teach Computer Science in the UK at A Level, and our weapon of choice
in the classroom is Netbeans. I have been trying to create some
student-proof recipes for persistence and ORM across Desktop Swing,
Desktop JavaFX and Jakarta EE Web. Up until now we have been using NB 15
and butting up against the problem that 15 does not support the new
jakarta namespace for persistence. This leads to issues with JavaFX and
other JPMS modular applications: to be actually able to package JavaFX
apps that can be distributed to users, you need your project to be
properly JPMS modular. For modular you need EclipseLink 4.0.2.
EclipseLink 4.0.2 is JPA 3.1 which uses the new jakarta namespace. NB 15
persistence wizards cannot cope with anything beyond JPA 2.2. NB 19
works partially, but fails to recognize Jakarta entity classes when you
try to create the controller classes.
I have been testing 20-RC4 and am happy to report that so far, RC4
persistence wizards seem to work with correctly with JPA 3.1, except for
two glaring caveats:
1. There are no JPA 3.1 libraries in the Libraries list. Without a
suitable entry in the list, JPA 3.1 does not appear as an option in the
wizards, e.g. the Persistence Unit wizard. The project dependencies seem
to have no effect on this. This can be worked around by creating a new
library entry yourself and adding the jakarta persistence API,
EclipseLink and Jakarta Activation API, plus javadocs and sources. This
is a fiddly process.
2. If you do add the library entry, The new API is 'unlocked', but is
incorrectly identified in the dropdown of the persistence unit wizard as
EclipseLink (JPA 3.0)
I am unsure as to whether to raise both of these as issues. Opinions please?
Thanks
Stephen Parry
