gwt and jaxb error

Question

I am using eclipse galileo with gwt.

I'm getting the following errors:

No source code is available for type javax.xml.namespace.QName; did you forget to inherit a required module?
No source code is available for type javax.xml.bind.JAXBElement<T>; did you forget to inherit a required module?

I tried adding jaxrpc.jar to library path, and also download source of QName.java (i've put it at src/javax/xml/namespace/QName.java). But nothing helped.

Here is the file making me problem - It is auto generated:
