Re: JAXBException when streaming XML response

[doug-6]

Thank you Colm. I extended the BinaryDataProvider[1] and added this provider
to my jaxrs:server. Success!

[1]
@Produces({"application/custom+xml"})
@Provider
public class StreamingXMLBinaryDataProvider extends BinaryDataProvider
{}

Have you tried explicitly adding the BinaryDataProvider as a JAX-RS
provider? Here's an example that explicitly adds the JAXBElementProvider:

JAXBException when streaming XML response

[doug-6]

I'm using CXF 3.1.7 to create a JAXRS service that uses  with
no custom providers. I'm trying to send a stream of data back in the http
response using content-type application/custom+xml. The http response entity
is set to an instance of a class that implements
javax.ws.core.StreamingOutput. When requesting this resource, I get a http
500 error that states "JAXBException occured: class com.MyStreamingOutput
nor any of its super class is known to this context. 

I stepped thru CXF source code via remote debugger and see that the
JAXBElementProvider is being chosen, likely because of  content-type
application/custom+xml. If I change my http response to use  content-type
application/customXml, the BinaryDataProvider is used and the response body
is what is desired. 

However, I need to return content-type application/custom+xml. What is the
best way to configure  so that content-type
application/custom+xml can be returned using a http entity that implements
javax.ws.core.StreamingOutput? I prefer not to use JAXB as I know the XML is
valid/well-formed.
