A question on SDO 2.0

Dear all,
   
  We are using tuscany SDO implementation. There is a problem that we can not resolve. Would you please kindly give some hints.
   
  We hava schema 
   
  <?xml version="1.0" encoding="UTF-8"?>
  <schema targetNamespace="http://stf.ibm.com/Computer"
      elementFormDefault="qualified" xmlns="http://www.w3.org/2001/XMLSchema"
      xmlns:tns="http://stf.ibm.com/Computer">
   
  
      <complexType name="Computer">
          <sequence>
              <element name="type" type="string"></element>
              <element name="price" type="string"></element>
          </sequence>
      </complexType>
   
  
      <element name="computer" type="tns:Computer"></element>
   
  
  </schema>
   
  We use XSD2JavaGenerator and get a interface "Computer" and class "ComputerImpl". How can we load a XML and get a "ComputerImpl" instance? Currently, we can only load a XML as a DataObject. And we can not find a way to cast the DataObject to the "ComputerImpl" Java Object.

You should be able to cast the DataObject to the Computer interface. If 
you can't my guess is that you didn't register the metadata, by calling 
the generated Factory.register() method, before loading the XML.
