Re: [OJB-developers] Refresh/update an object

[Thomas M. <tho...@ho...>]

Hi Travis,


Say you have a persistent object instance.
To perform a refreh of this object use

PersistenceBroker broker = PersistenceBroker.createPersistenceBroker();
Identity oid = new Identity(instance);

broker.invalidate(oid);
instance = broker.getObjectByIdentity(oid)


HTH,

Thomas
