Sorry, but I'm afraid that you are completely on the bad track : - Google App Engine JPA supports only some subset of JPA implementation, it is unlikely that your existing-not trivial JPA application will migrate to Google App Engine without hefty coding. More probably that you can migrate smoothly to the "pure" DataNucleus - just opposite as you mean. - Google App Engine does not support any RDBD database, the only persistence layer supported is 'datastore' backed by Google Big Table.
I suggest you to read : http://code.google.com/appengine/docs/java/datastore/ Although it is focused on JDO it is also relevant to JPA. The underlying technology (Big Table) is exactly the same. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
