how can i implement a save-update property but assigned a calculate id by my program??

You can try this way

Session s = null;

try{
s= getSession();
Transaction trans = s.beginTransaction();
ClassName instance= (ClassName ) s.get(ClassName .class, xxx);

//set the values

s.update(xxx);
trans.commit();



xxx: instance from POJO class whcih acts as the primary key.
