Re: [eclipselink-users] Eclipselink 1.1-M4 create OSGI EntityManagerFact

[Erasmo <einundswanzig@xxxxxxxxx>]

Yes tim, everything works ok with the 1.0.1 i have even tested over 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.
