hibernate and instance aliasing

We are having problems with instance aliasing in our application. I
was hoping that the secondary cache would fix the problem. But alas it
doesn't. Basically we create an object A and store it. Another piece
of code in the same JVM does a query and finds object A and
instanciates it. However, the application now has two instances of the
same "object" (or db record.) We need it to return the same instance.
Does hibernate support this mode?


AliasTest at = new AliasTest();
at.setName("name1");
at.setNumber(4);
{
Session session = factory.openSession();
Transaction tx = session.beginTransaction();
session.save(at);
session.saveOrUpdate(at);
tx.commit();
session.close();
}
System.out.println("AliasTest=" + at);
AliasTest mimic;
{
Session session = factory.openSession();
mimic = (AliasTest)session.get(AliasTest.class,
at.getPid());
System.out.println("mimic=" + mimic);
System.out.println("mimic same as prev aliasTest?" + (mimic
== at));
session.close();
}
System.out.println("mimic=" + mimic);
mimic.setNumber(45);
System.out.println("mimic=" + mimic);
System.out.println("AliasTest=" + at);
System.out.println("mimic equals?"+mimic.equals(at));
System.out.println("mimic same as prev aliasTest via getNumber
check?"
+ (mimic.getNumber() == at.getNumber()));
