jpa - Hibernate Problem ( javax.persistence.PersistenceException: org.hibernate.PersistentObjectException) -


here problem description.

i have 2 objects "a" , "b"."a" has onetoone(cascadetype= cascadetype.all) relationship object "c".even "b" has onetoone(cascadetype = cascadetype.all) relationship "c".

now need persist object "a".and after persist object "a" ,i need persist object "b".i can persist object "a" ,but when persist "b" exception

javax.persistence.persistenceexception: org.hibernate.persistentobjectexception

the reason object "c" persisted when "a" persisted.and when "b" being persisted tries persist "c" again.thats why persistenceexception.

i tried merge object c before persist object "b".even same exception.

please provide me work around.

also let me know if 1 needs further info.
