Hi
I want use an O/R in a long-transactional application (multitier) that
concur
with another application that makes direct access on my db. I'm tring
Castor
that matches all requirements but I found that id does not manage a
situation
as I want; this is the code
db = _jdo.getDatabase();
// First transaction: I read the value object
db.begin();
TestataOrdineVO to= (TestataOrdineVO) db.load(
TestataOrdineVO.class, new Integer(1) );
db.commit();
// Second transaction: I read the same value object
// In the next row I put a breakpoint and before resume I modify the
// field Codice_Ordine on my db
db.begin();
TestataOrdineVO t0= (TestataOrdineVO) db.load(
TestataOrdineVO.class, new Integer(1) );
System.out.println(t0.getCodiceOrdine());
db.commit();
The value printed is the old value! Infact the object loaded in the second
transaction comes from the cache.
Is there a solution to have the real value? May I "bypass" the cache system
in any way?
DB: Sql Server 2000
