Entity in two persistence units

Hi,

I have two persistence units in one persistence.xml
Each persistence unit connected with separate database and using Hibernate.
say Entitymanager em1 for persistence unit1 and
Entitymanager em2 for persistence unit2.
I get an entity from em1 using JPQL and it has values.
I want to persist this entity with em2.
I am getting an error "detached entity passed to persist."

Can some one post how do achieve this ?

Thanks
Kathir

Did you try to merge the object with em2

Yes, the merge is working fine.

thank you
