T5: Hibernate and services

[Angelo Chen]

Hi,

I have some tapestry-hibernate related questions:

1) if I have two concurrent services(A and B), each has Session injected. do
A and B have their own transaction?

2) I have a table config that has a field 'nextID':

  2.1 IDService has a method 'NextID()' which get the value from
'nextID' and increment it
  2.2 AppendSerivce which uses IDService's NextID to get a number and
assign to a new object, persist it

if I have two instances of UserService(A and B) running, A will be
successful in getting a new ID while B fails because it gets the same ID as
A, any idea how to solve this problem?

Thanks,

Angelo

Dependends on the version of Tapestry.  Earlier versions included an
automatic commit.

 Hi,

 As what I understand now that transaction has to be committed to persist the
 objects, following is a diapatcher, there is no commit, but the new PageLog
 got persisted too, any idea? thanks,

Hi,

This is version 5.0.13, and I turned off the auto commit,
 property name=hibernate.connection.autocommitfalse/property
