PB Tutorial: Query By Criteria on Object

[Annapoorani Rathi]

Hi,
 
I just started on OJB..
 
In PB Tutorial, the code snippet does not fetch me the record and result is 
null (though the record is present in DB)
 
 broker = PersistenceBrokerFactory.defaultPersistenceBroker();
 QueryByCriteria query = new QueryByCriteria(template);
 result = (Product)broker.getObjectByQuery(query);
 
But if i replace the above with the code below, i do get a populated result 
object

 broker = PersistenceBrokerFactory.defaultPersistenceBroker();
 Criteria criteria = new Criteria();
 criteria.addEqualTo("name","Sprocket");
 QueryByCriteria query = new QueryByCriteria(Product.class, criteria);
 result = (Product)broker.getObjectByQuery(query);
 
I understand that the first Impl decodes to Second internally.
But then the first Impl does not work.

Can anyone help me to reason out?? 
 
Thanks
Anna
