Thanks for the pointer, Patrick.
I've created a MoneyValueHandler based on the PointHandler example. So
far so good.
Now I'm struggling to see how I configure my handler into OpenJPA.
I've tried adding this line to my persistence.xml
<property name="openjpa.jdbc.MappingDefaults"
value="FieldStrategy='couk_cleverthinking_gwappo_db_money=couk.cleverthinking.gwappo.db.MoneyValueHandler'"/>
but it seems to have no effect, ie. my handler is not being invoked.
I'm guessing I've got the configuration wrong or missed a step, but I
can't seem to find any examples on how to achieve this.
very best wishes
Roy
