Cannot persist simple entity with Hibernate when run in an OSGI server(Works in a standalone Java application) -

i starting use hibernate-jpa. not know in deep how works, though know jpa specification fair extent.

i have single entity address, has no relationships whatsoever. has primary key id has @generatedvalue annotation , 4 other fields. instantiated entitymanagerfactory, entitymanager, address object , called em.persist(address);

i error org.hibernate.propertyaccessexception: not field value reflection getter of com.sac.hbn.address.id.

i running in osgi server, when run in standalone application works without issues.

https://hibernate.atlassian.net/browse/hhh-9434 issue facing asker there mentioned when changed 4.3.6 4.3.5 worked him. me tried 4.3.2,4.3.5,4.3.6 gave me same behavior.

any idea why?

solution : worked through unexpected solution. thing there persistence provider eclipse link configured in server. tries pickup bundle has meta-persistence tag in manifest. not know how connected issue facing removed tag, started working!

i'm guessing setid (and other setters) must return void, , jpa implementation getting confused because don't. try changing them return void instead.
