How do I get equivalent functionality of the
<additionalTypes>section in the config for wscompile using either the new wstools or the annotations?
I have added a feature request for this, and have scheduled it for 1.0.2:
In the meantime, you could define a dummy method that references all of the subclass types, this will force the jaxrpc-mapping and wsdl to contain the types.
It's not elegant, but it would save you from hand-editing the files.
