Since we should be using jaxb for metadata that is annotated with it, and I see that you can use jaxb even when its not annotated, I'm looking at that instead. For metadata like the datasource which does have jaxb annotations:


  |    public void testJaxbMCFXml()
  |       throws Exception
  |    {
  |       ManagedConnectionFactoryDeploymentGroup mcfs = initMCFDG();
  |    
  |       JAXBContext ctx = JAXBContext.newInstance(ManagedConnectionFactoryDeploymentGroup.class);
  |       Marshaller marshaller = ctx.createMarshaller();
  |       marshaller.setProperty("jaxb.formatted.output", Boolean.TRUE);
  |       QName mcfsName = new QName("datasources");
  |       JAXBElement<ManagedConnectionFactoryDeploymentGroup> root = new
  |          JAXBElement<ManagedConnectionFactoryDeploymentGroup>(mcfsName,
  |                ManagedConnectionFactoryDeploymentGroup.class, mcfs);
  |       marshaller.marshal(root, System.out);
  |    }
  | 

with initMCFDG() populating the mcfs similar to that shown above, jaxb output produces:
