How can you replicate Hibernate's saveOrUpdate in JPA?

Question

In JPA, is there any way you can replicate Hibernate\'s saveOrUpdate behavior,

saveOrUpdate

public void saveOrUpdate(Object object)
                  throws         


        

Answer 1

Try using the EntityManager.merge method - this is very similar.

There is an excellent description of the differences in Xebia's blogpost: "JPA Implementation Patterns: Saving (Detached) Entities."
