Thank you for fast respond, but "oi" is Not persistent object it's used only
as "Info" exchange container for remote invocations,
so Castor need not even touch "oi".And how about JBoss integaration? It only
works with DbLocked attribute.Why?
public class OrderInfo implements java.io.Serializable{
private boolean created= false;
int order_sno;
String order_kod;
String o_name;
//accessors for fields
}
P.S.
getInfo/setInfo in OrderStore only read/save fields from Store to Info.
