That's all true Tom and i didn't figured out until yesterday so i
downloaded the preview jar and ran it against it. I had some problems
getting working the thing with nightly build 2907 which until yesterday
appear to be the most recent (today appeared another one 2918) i will
post the exception and other stuff today if that might be useful, anyway
when i found that problem with 2907 i decided to download and older
build 2887 and everything works, i haven't tested extensively but if i
found something i will post it. So resuming for everyone there trying
to make it work with 2.0 i did it work with:
1.1.0 Nightly Build 2887 (20081204)
http://dev.eclipse.org/viewsvn/index.cgi/trunk/jpa/plugins/javax.persistence_2.0_preview.jar?root=RT_Eclipselink&view=log
<http://dev.eclipse.org/viewsvn/index.cgi/trunk/jpa/plugins/javax.persistence_2.0_preview.jar?root=RT_Eclipselink&view=log>
persistence 2.0 bundle required as Tom said.
If the older javax.peresistence 1.99 jar is still there delete it, in my
personal experience that cause me a problem.
Finally this is the way i got a EntityManagerFactory within osgi:
HashMap<Object, Object> properties = new HashMap<Object, Object>();
properties.put(PersistenceUnitProperties.CLASSLOADER,
this.getClass().getClassLoader());
factory = new PersistenceProvider().createEntityManagerFactory("x-unit",
properties);
Additional you might need to import the org.eclipse.persistence.config
AND org.eclipse.persistence.jpa.osgi packages to make this work.

Hi Erasmo,
The reason you are seeing the ClassNotFoundException on 1.1 is that
1.1 has
started to integrate support for the upcoming JPA 2.0 spec.
LockTimeoutException (and some other classes) are new to that spec.
You should
be able to solve that problem by getting a new version of the
javax.persistence
bundle. Try getting it from our subversion repository:
http://dev.eclipse.org/viewsvn/index.cgi/trunk/jpa/plugins/javax.persistence_2.0_preview.jar?root=RT_Eclipselink&view=log
<http://dev.eclipse.org/viewsvn/index.cgi/trunk/jpa/plugins/javax.persistence_2.0_preview.jar?root=RT_Eclipselink&view=log>
If you are having other problems getting OSGi working, please post
the exact
problems. The demo ran successfully for me recently, so some more
details about what you are doing, would help me understand the deltas.

Yes tim, everything works ok with the 1.0.1 i have even tested
over 1.0.2. <http://1.0.2.> <http://1.0.2.> Right now im trying
the milestone 4 of 1.1 and i get a:
java.lang.ClassNotFoundException:
javax.persistence.LockTimeoutException
Some other nightly builds broke not being able to find
PersistenceProvider. And it looks like the
javax.persistence.Persistence aproach doesnt work under osgi
breaking when they try to find or load the the PersistenceUnit.

Doug Clarke should be able to answer you, the osgi EMF

I dont have the latest build in front of me at the moment,
but I wrote
the tutorial around the 1.0.1 OSGI release.
