Question

I am having trouble starting up an old application that was working fine, but now that I need to make some changes it complains about old sdk (1.5.x) so I am moving to the 1.7.0. However when I deply I get the error, in the local it runs just fine, so I have no idea what is the problem.

The error in question is the missing class from datanucleus.

Class org.datanucleus.store.appengine.jdo.DatastoreJDOPersistenceManagerFactory

Here are the dependencies. Any idea
