Damon,.
when asking us for help, please try to send us as little information as possible, as
otherwise we would have to plough through endless class mappings
on the search for the correct one. Given the time we spend to help you out, I hope
that we are not asking too much.
To help you with your problem, have a look at the following field mapping taken from
your mapping file:
<field name="RdccTime"
type="com.jbhunt.rdcc.application.RDCCJobTime"
collection="ewe.util.Vector">
<bind-xml name="rdccTime"/>
</field>
Assuming that you've read the documentation about available collection types when
specifying 1:M relations, it should be plainly obvious that you
cannot use your own collection classes with the collection attribute. Possible values
(amongst others) are collection, arraylist, etc.
