You can not directly use genrator class for property fields(non primary) in hibernate mapping, but your requirement can be acheived through formula of property.

yes thanks for yo reply
is it possible to combine two tables with the single formula

say for examble i have 3 tables A, B, C
B and C are sub tables of A

A = id (primary)
B = id (primary), requestId(property)
C = id (primary), requestId(property)

here id is common for all the 3 tables for a record.
now want to have a formula for requestId.
and tht should be in sequence. unique for the tables B and C

any idea???
