Re: [eclipselink-users] Eclipselink 1.1-M4 create OSGI EntityManagerFactory
|
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
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.> 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 creation can be
a moving target.
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.
