Arnaud, Here is the situation:
I am not _directly_ creating elements (in the XML schema) from
some of my complexTypes because they are _derived_ (subclass)
types, declared using <xsd:extension base=...>
Here's the relevant part of the schema:
<xsd:schema xmlns:xsd=
"http://www.w3.org/2000/10/XMLSchema";
targetNamespace=
"http://zzzzzyyyy.com/OurCurrentProject";>
<xsd:include schemaLocation="MyClass.xsd"/>
<xsd:complexType name="MyClass">
<xsd:complexContent>
<xsd:extension base="AParentClass">
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
</xsd:schema>
In the above, I want the generated Java code to create code that
says MyClass extends AParentClass. This _is_ happening. However,
the next thing I want to do is to create an _instance_ of MyClass
in my Java code. Of course this fails since MyClass is abstract.
I am using the 'element' method. When I used the 'type' method,
we could create class instances (since they were not abstract)
and they marshaled out just fine, but had class cast problems
when trying to unmarshal.
