Paul,
Thanks for your help.
I tried this approach, but I am not seeing the SOP made it to my
console. I suspect whether my custom stream writer is used at the first
place. Is there a way to tell Jersey/Java to use my custom writer
instead of the default writer?
I see this in the console, which tells that at least my message body
writer was loaded properly.
INFO: Provider classes found:
class impl.rest.jaxb.CDATAProvider
Here is my MBW writer which uses the custom stream writer.
@ProduceMime("application/xml")
@Provider
public class CDATAProvider implements MessageBodyWriter<CellType> {
public void writeTo(CellType cellType,
Class<?> type, Type genericType, Annotation annotations[],
MediaType mediaType, MultivaluedMap<String, Object> headers,
OutputStream out) throws IOException {
try {
JAXBContext jc = JAXBContext.newInstance(CellType.class);
Marshaller marshaller = jc.createMarshaller();
XMLStreamWriter swImpl =
XMLOutputFactory.newInstance().createXMLStreamWriter(out);
XMLStreamWriter sw = new MyStreamWriter(swImpl);
marshaller.marshal(cellType, sw);
} catch (XMLStreamException xse) {
System.out.println(xse.getMessage());
} catch (JAXBException je) {
System.out.println(je.getMessage());
}
}
public boolean isWriteable(Class<?> type, Type genericType,
Annotation annotations[]) {
return CellType.class.isAssignableFrom(type);
}
public long getSize(CellType cellType) {
return -1;
}
}
Best regards,
Arul
