does Tapestry-Hibernate
allow multiple Hibernate sessions? if not, any solution to this?
Thanks.
Yes, you can grab the HibernateSessionSource and call create to get a
second session.
You are responsible for this session, so make sure you close it.

Hi,
I have a need to generate a sequential ID for employee entity, the
entity
has its own primary key which is auto incremented. I use a one-
record table
that has a field 'next_id', every time when a new employee is added,
I'll
just get that record and increment the field, this works most of the
time,
but if there are multiple workstations adding new employees, problem
will
happen, it will have this 'dead lock' issue. I'm thinking of
accessing/incrementing the one-record table to be in a separate
Hibernate
session, it will immediately flush after incrementing the 'next_id',
this
will leave a very small window for that record to be locked and
allowing
other workstations to continue, and question is, does Tapestry-
Hibernate
allow multiple Hibernate sessions? if not, any solution to this?
Thanks.
