unique id generation for all DB vendors


I have a project which is developed using hibernate- jpa annoatation.

I have chance to create id using JPA which are AUTO, Increment, sequence and table.

Auto is working fine for all DB vendors but, it increase the id for all table together.

Ex: Table a - id is 100

table b id is 101.

c id is 102.

i wanna have ids like

For table A id should be 100 to 1000

For table B id should be 100 to 1000

for all tables also.

I don't want to create separate sequence & Table and make DB fill.
 
It is sorta covered in the JavaRanch Style Guide.
