Hi Frank,
To be more compliant with XML Schema, Castor uses the Schema type by
default. Currently the only way to over-ride this is to remove the
Schema type from the generated descriptors. If the Schema type is null,
Castor will use the java class name. So you need to modify the generated
descriptors, find the appropriate field descriptors and set the schema
type to null.
Since overriding descriptors manually is a pain and would need to be
done each time you generate the source code, the approach I usually take
when faced with this is to create a custom ClassDescriptorResolver (it
could extend Castor's default ClassDescriptorResolverImpl) that upon
loading a class descriptor will automatically handle the changes I want
to make.
