I think the problem is that when you set many=true then the attribute
becomes a list rather than a bare type (otherwise there is no way to add
multiple attributes). You need to do:
List<int> custNum = new ArrayList();
custNum.add(1000);
createdDO.setList("custNum", custNum);
I didn't see the custNum element in your XSD so I don't know if you want
to do the above or remove the many=true property.
