There is another problem you must know...in the four cases, I used @Transacational or em.flush...
I have removed the following in the persistence.xml.

<property name="hibernate.transaction.flush_before_completion" value="true" />

Without em.flush(creat1, create2), even there is a @Transacational on method, the data will not be saved. 

Maybe I could create another issue about this?
