Re: How to map embedded value object?

[Robert r. Sanders]

I believe that I was able to get something like the following to work.  
I don't have the exact file avaliable right now so this is my best shot....

	<field-descriptor 
        name="money->amount"
        column="moneyAmount"
        jdbc-type="LONG"
       />

	OR

	<field-descriptor 
        name="money.amount"
        column="moneyAmount"
        jdbc-type="LONG"
       />



and

        

	<field-descriptor 
        name="money.currency"
        column="moneyCurrency"
        jdbc-type="VARCHAR"
      />

Hi,
As stated in Martine Flower's artice
(http://martinfowler.com/eaaCatalog/embeddedValue.html)
"Many small objects make sense in an OO system that
don't make sense as tables in a database. Examples
include currency-aware money objects and date ranges.
Although the default thinking is to save an object as
a table, no sane person would want a table of money
values.". In OJB, how these small objects are mapped
to the same table of their master object?
