Hi Keith,
I tried adding the collection="array" array, but it didn't seem to make
any difference.
Here is the error I received. It seems like in the 2D case, it's having
a hard time determining what sub_product should map to.
--------------------ERROR
wrapper-element: data_array

'sub_product' in ClassDescriptor of sub_product

java.lang.String, java.lang.String, org.xml.sax.Attributes)

I have attached my complete mapping file as well as the output of my
Marshalling process.
Do you have any other ideas?

Matt,
Did you try adding collection="array" to your mapping?
