Hibernate version: 3

I want to load an object like credit card table from db . set the number as decrypted one and send it to view layer to show it. But after set, it sets it in data base also. I dont want to set in db.
How can I stop it?

You are probably running into auto-flush. Read about FlushMode here:
http://www.hibernate.org/hib_docs/v3/ap ... hMode.html

and here:
http://www.hibernate.org/hib_docs/v3/re ... e-flushing

Try setting FlushMode.COMMIT on the session and see if that solves your problem.

I have another solution..
1. CreditCard cc = currSession.get(CreditCard.class, new Integer(id));
2. tx.commit();
3. session.close();
4. //At this point cc is a detached object...
5. cc.setCode(yourCode);


etc...

I'm a newby so, If I'm making a mistake, please let me know!

I learn from my mistakes!

you might want to set update="false" for the property in the mapping file.

Why disable update at mapping level just for a particular scenario?

Actually, I am using jta . so I dont handle transaction management in my code. But I tried session.close() , session.evict(CreditCard) , session.clear() before set , but none of them worked.

Right now I tried session.setFlushMode(FlushMode.NEVER) and COMMIT as you said, but didnt work also.

I tried <attribute name="FlushBeforeCompletionEnabled">false</attribute> in my jboss-service.xml. It didnt work also.

i said might. :) depends on the situation, if it's something like a credit card number that wouldn't change once it's been inserted.

Thank you ,
I tried update="false" and it worked for this situation, but I dont know the solution for some attributes that are updatable after insertion.

Just calling the setter method should not cause -anything- to happen with the database. Read the Hibernate docs on when flushes occur (when things are actually changed in the database). Session.evict should work fine -- are you sure you're passing in the right object. Posting code would probably help a lot at this point, since you've received a few good suggestions that you claim are not working.

private List<PaymentCcards> decryptCcList(List<PaymentCcards> pcc){
PaymentCcardsDAO dao = new PaymentCcardsDAO();
List<PaymentCcards> ret = new ArrayList<PaymentCcards>();
Encrypter encrypter = new Encrypter();

// here getSession().clear() or close() didnt work also
for (PaymentCcards pc : pcc) {
//dao.getSession().evict(pc); //this evict didnt work
try {
if(pc.getNumber()!=null && pc.getNumber().trim().length()>0){
String decryptednumber = encrypter.decryptdata(pc.getNumber());
pc.setNumber(decryptednumber);
ret.add(pc);
}
}
catch (Exception e) {e.printStackTrace();log.error(e.getMessage());}
}
return ret;
}
