I'have a serioud problem to het DataNuclues and JPA EntityManager to work in combination with Spring 3. I have this exception: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/ spring.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: Provider error. Provider: org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider:
When digging deeper I also noticed this one: org.datanucleus.exceptions.ClassNotResolvedException: Class "com.footdex.test.appengine.api.urlfetch.HTTPRequestMatcher" was not found in the CLASSPATH. Please check your specification and your CLASSPATH. And this is true as I'm compiling test classes to another target directory and not in WEB-INF/classes. When I remove the test classes from the Eclipse build path everything works fine. If I don't use the EMF but the low-level datastore API it doesn't matter that test classes are not in WEB-INF/classes, so it seems DataNuclues or the GAE javax.persistence.Persistence implementation is doing something special here... I checked my project setting and I'm only enhancing ORM classes in src/ main (here are my app sources). Sources in src/test (here are my test sources) are not configured to be enhances. I'm wondering what is wrong, and more importantly how I can fix this. Cheers, Marcel
