Use JAXB unmarshalling in Weblogic Server

Hi,
In the project we need to develope a mail system. This must do common work with the webservice. We create a Bean who recieves an auto-generated class from non-root xsd element (not wsdl); this bean do this common work. The mail system recieves a xml with elements defined in xsd file and we need to drop this elements info to wsdlc generated classes. With this objects we can use this common bean. Is not possible to redirect the mail request to the webservice.
We've looking for the code to do this with WL9.2 resources but we don't found anything. At the moment we've tried to use JAXB for this unmarshalling:
JAXBContext c = JAXBContext.newInstance(new Class[]{WasteDCSType.class});
Unmarshaller u = c.createUnmarshaller();
WasteDCSType w = u.unmarshal(waste, WasteDCSType.class).getValue();
waste variable is an DOM Element object. It isn't the root element 'cause the root isn't included in XSD
First we needed to add no-arg constructor in some autogenerated classes. No problem, we solved this and finally we unmarshalled the xml without error Exceptions. But we had problems with the attributes. The unmarshalling didn't set attributes; none of them in any class, not simple attributes, not large or short enumeration attributes. No problem with xml elements of any type.
We can't create the unmarshaller from "context string" (the package name) 'cause not ObjectFactory has been create by wsldc. If we set the schema no element descriptions are founded and unmarshall crashes.
This is the build content:

</module>
</jwsc>
</target>
My questions are:
How Weblogic "unmarshall" the xml
with the JAX-RPC tech and can we do
the same with a xsd element?
How can we do this if yes?
If not, Exists any not complex
solution to this problem?
If not, must we use XMLBean tech. or
regenerate the XSD with JAXB tech.?
What is the best solution?
NOTE: There are not one single xsd but a complex xsd structure in fact.
