[appengine-java] Re: JPA enhancement problem (DataNucleus)
I get this issue pretty often too, although my experience is that you likely have an issue with one of your entities (sometimes your entity can be properly coded, but there could be a fluke with how DataNucleus +GAE interpret a particular feature/annotation, especially with JPA). For example, I had an entity that would fail DataNucleus validation at first, but when I would do a Clean All+Auto Build, the Datanucleus error would go away until some other class (any java class) was re- compiled. I ended up discovering this by iteratively removing JPA features from my Entity one at a time (@OneToOne relationships, etc) until the this class not enhanced errors went away). Eventually I was able to nail down that I was either annotating something incorrectly or DataNucleus/GAE didn't support a particular feature, or in one case an actual bug. Not exactly a clear-cut answer, but that's the path I took.

[appengine-java] Re: JPA enhancement problem (DataNucleus)
They aren't that complex, and I never really got any compile-time errors (which I think you are referring to) - all the issues are run- time. Anyway, I went ahead and limited the ORM compiles to just the subdirectory that has the entities (using the Eclipse GAE option). Hopefully that'll fix the errors; will report back if it doesn't.

[appengine-java] Re: JPA enhancement problem (DataNucleus)
there could be a fluke with how DataNucleus+GAE interpret a particular feature/annotation The log would tell you if that was the case. More likely the GAE/J Eclipse plugin of hasn't detected a change in the source file. Obviously there is also the DataNucleus Eclipse plugin to use ... -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Hi, I had this problem, and after try to clean your project and rebuild it . bye On 12 mar, 19:34, Rajeev Dayal rda...@google.com wrote: Hi there, Can you provide the full error message that you're seeing when you get this error? Also, can you navigate to the Error Log (Window - Show View - Error Log) and see if there are any errors related to this problem listed there?
