I try to start an Google appengine application in my eclipse.

I have the Google plugin and I set the sdk for my application.

But, when I start this one, I get the following error:

java.lang.ClassNotFoundException: org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider

However, this class is present in the sdk which is present in my classpath.

Why Appengine doesn't find this class ?

Thanks.
