=========================================

code:

public void testSaveOrUpdate() {
PigeonholeRule pigeonholeRule = new PigeonholeRule();
pigeonholeRule.setXtypeSymbol("IMAGE");
pigeonholeRule.setSize(new Integer(2));
PigeonholeType pigeonholeType = new PigeonholeType();
pigeonholeType.setSymbol("none");
pigeonholeRule.setPigeonholeType(pigeonholeType);


pigeonholeRuleDao.saveOrUpdate(pigeonholeRule);
pigeonholeRuleDao.update(pigeonholeRule);
// assertEquals(pigeonholeRule,pigeonholeRuleDao.loadByPrimaryKey("IMAGE"));
try {
Session session = sessionFactory.openSession();
session.saveOrUpdate(pigeonholeRule);
System.out.println("xxxxxxxxxxxxxx");
} catch(Exception e) {
e.printStackTrace();
}
PigeonholeRule obj = pigeonholeRuleDao.loadByPrimaryKey("IMAGE");
System.out.println(obj.getSize());

}


===================================
mapped classes:

public class PigeonholeRule implements Serializable {

private String xtypeSymbol;
private Integer size;
private Xtype xtype;
private PigeonholeType pigeonholeType;
}

public class PigeonholeType implements Serializable {
private String symbol;
private String title;
private PigeonholeRule pigeonholeRule;
}

public class Xtype implements Serializable {
private String symbol;
private String title;
private String note;
private PigeonholeRule pigeonholeRule;
private Set xtypeDefaultActions;
private Set xources;
private Set xtypeActions;
}

public Serializable save(PigeonholeRule obj) throws DataAccessException {
Session session = null;
try {
session = sessionFactory.openSession();
session.save(obj);
return obj;
} catch (HibernateException he) {
throw SessionFactoryUtils.convertHibernateAccessException(he);
} finally {
SessionFactoryUtils
.closeSessionIfNecessary(session, sessionFactory);
}
}

it seems I've found the error.

I write begainTransation it saved the obj;

session = sessionFactory.openSession();
tx = session.beginTransaction();
session.saveOrUpdate(obj);
tx.commit();

====================
but why DAO class generated by middlegen didn't use transation
it seems it could not use the transaction in codes? is it right?


public void update(CarrierType obj) throws HibernateException
{
Session ss = sessionFactory.getSession()
ss.update(obj);

it can update now . but it can't insert new.
