I have been struggling with getting JPA/EclipseLink working properly. After
following the instructions on the wiki for GlassFish development
(http://wikis.sun.com/download/attachments/209655166/GF-OSGi-Features-1.0.pdf),
I was finally able to get past the problems I was having with persistence units
not being found.
My issue now is that when I try to create an EntityManager from the EMF, the
database drivers for H2 can't be found. I have copied the H2 jar into
domain/lib and verified that it has the same permissions as the other libs that
are there that are working.
The stacktrace is below. Any thoughts? I'm out of ideas.
Thanks,
Chris
