Mauricio, did you ever get this working with DataNucleus JPA? I'd switch from my EclipseLink attempts to DataNucleus, if I knew someone else got it to work. A persistence provider isn't specified by the new GPE JPA facet configuration tool, when it creates a new persistence.xml, so I'm wondering if that's necessary. -Bill

org.datanucleus.exceptions.NucleusUserException: There is no available StoreManager of type "rdbms". Please make sure you have specified "datanucleus.storeManagerType" correctly and that all relevant plugins are in the CLASSPATH
I'm using these DataNucleus references:
http://www.datanucleus.org/products/accessplatform/jpa/emf.html
http://www.datanucleus.org/products/accessplatform/persistence_properties.html
And here's the relevant part of my persistence.xml:
<persistence-unit name="pu-searchindex-1">
<provider>org.datanucleus.api.jpa.PersistenceProviderImpl</provider>
<properties>
<property name="javax.persistence.jdbc.driver" value="com.google.appengine.api.rdbms.AppEngineDriver"/>
<property name="datanucleus.ConnectionURL" value="jdbc:google:rdbms://commentous.com:web-prod:searchindex-1/ctssearchidx"/>
<property name="datanucleus.autoCreateTables" value="true"/>
<property name="datanucleus.storeManagerType" value="rdbms"/>
<property name="datanucleus.jpa.level" value="JPA1"/>
<property name="datanucleus.jpa.addClassTransformer" value="false"/>
</properties>
</persistence-unit>
