jboss-user:
i have decided to create a table "Trans" with a pk
"transno" of type bigint without auto-increment
defined. next i created a table "counter" with one
field "cnt" which stores the last value of "transno"
of table "Trans". I have an autonumber entity bean
(cmp) to map this bean to table "Counter", which
provides the value of "cnt" for later retrieval. next
i wrote a session bean called AutoNumberManager to
provide the actual increment logic ("cnt = cnt + 1").
with this approach, should i worry client's concurrent
access of AutoNumberManager sesion bean?
thanks in advance.
