that's funny because it seems to "work"; well when I say work, em.persist() of such an entity does not throw ... I'll see what happens when I try to query an object with such a key ...
errr ... also parenthetically, if it doesn't support @EmbeddedId then it's not really a conformant implementation of JPA ... :D btw why does em.flush() throw an exception declaring that it requires a transaction and that there is none in context when the Persistence Provider is clearly configured for non transactional read/writes, surely a flush() would either silently "do nothing" or commit/write any pending objects to the ds??? :) Thanks - larry On Aug 26, 2:57 pm, "Jason (Google)" <apija...@google.com> wrote: > You have four choices for key type which are described > athttp://code.google.com/appengine/docs/java/datastore/creatinggettinga.... > An embedded Id won't work with App Engine since it can't be naturally > represented as a Key object. > - Jason > > > > On Tue, Aug 25, 2009 at 2:09 PM, Larry Cable <larry.ca...@gmail.com> wrote: > > > I have given up, seems like this is not supported, the runtime > > complains that the "MyId" class is not a supported Key Class ... go > > figure ... > > > On Aug 24, 4:15 pm, Larry Cable <larry.ca...@gmail.com> wrote: > > > Has anyone managed to get @EmbeddedId with JPA to work in GAE/ > > > DataNucleus??? > > > > @Entity > > > public class MyEntity { > > > //... > > > @EmbeddedId public MyId id; > > > > } > > > > // ... > > > > @Embeddable > > > public class MyId { > > > //... > > > > public String id; > > > > } > > > > I'm getting an "unsupported primary key type" exception at runtime > > > during em.flush() > > > > any thoughts? examples of working code? > > > > I am pretty sure it's pilot error ... but the documentation for this > > > is pretty thin on the ground ... > > > > will try and isolate an actual "working" example and post that here > > > also ...- Hide quoted text - > > - Show quoted text - --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
