But since there is no "expression" attribute for a field-descriptor, you
would have to put an expression in the column attribute and this would
bomb. OJB tries to write to the column specified in the "column"
attribute when you call PersistenceBroker.store(object).

Why would it bomb ? On the contrary, fields that map to an expression
rather than to a column can only be readonly as far as the database is
concerned, so OJB would not even consider them during store
operations.
