How to use assigned primary key within entitybean?

[pxpwxj]

This is my case:i use entity bean to handle table b,b is just for store historical data for table a.So b need a primary key(it's the same as a),but i always should use the same primary key value from table a when i move the record to b from a.when use hibernate,i can use assigned primary key for b,but in ejb3.0,there is no primary key type correspond to the "assigned" type in hibernate!

is it a fault of ejb3?or,how can i sovle my problem?

pay respects!!

Use the same sequence for both tables. And make sure that the beginning of the sequnce is bigger than max(a.pk) so they don't overlapp.
