Hi

MonetaryAmount class from HiA book is immutable but when I try to code it using xDoclet and Spring's HibernateTemplate class, I run into a series of problems, in the end, to make it work I have to turn it into a mutable class with setter fields
for Currency and BigDecimal properties.

E.g.

Mapping for Item class with component mapping to MonetaryAmount as
reservePrice




Now my question is, is it possible to map an immutable class
with empty setter methods in hibernate using component tag?

If not possible, what's the practice you ppl use to map immutable class? (implementing UserType I guess..)


Thanks,

Sam

Problem solved.

Just have to use MonetaryAmountCompositeUserType
from HiA sample code to map immutable type with
empty setter methods for fields.

Using components tag in mapping simply won't work
because of empty setter unless you change MonetarAmount
to mutable class, defeats purpose of immutable fields

Lesson: use CompositeUserType to map immutable types

Mapping used in xDoclet:
