Raymond Feng commented on TUSCANY-874:
--------------------------------------
With the latest trunk code, the NPE has been fixed. Now I ran into a JAXB
marshalling issue. It seems that JAXB can only serialize root element.
org.apache.tuscany.spi.databinding.TransformationException:
javax.xml.bind.MarshalException
- with linked exception:
[com.sun.istack.SAXException2: unable to marshal type
"helloworld.jaxb.NameType" as an element because it is missing an
@XmlRootElement annotation]
