> RawXMLInOutMessageReceiver can be only used for JSON services for now [1].
> However, JSON/badgerfish builder can be improved by handling RPCMessageReceiver correctly. I can't attach the patch because i have copy pasted and created own formatters and builders(please find the source attached):
> 1) It is possible to solve the namespace problem described at [1] by explicitly converting JSON/badgerfish to SOAP in JSONbadgerfish builder :
> public OMElement processDocument(InputStream inputStream, String contentType,
> MessageContext messageContext) throws AxisFault {
> ....
> AbstractXMLInputFactory inputFactory = new BadgerFishXMLInputFactory();
> XMLStreamReader xmlReader = inputFactory.createXMLStreamReader(
> new JSONTokener(IOUtils.toString(reader)));
> OMNodeEx document = (OMNodeEx) new StAXOMBuilder(xmlReader).getDocumentElement();
> //removing parent
> document.setParent(null);
> //wrapping document with envelope
> SOAPFactory soapFactory = OMAbstractFactory.getSOAP11Factory();
> SOAPEnvelope soapEnvelope = soapFactory.getDefaultEnvelope();
> SOAPBody body = soapEnvelope.getBody();
> body.addChild(document);
> soapEnvelope.build();
>  //converting xml structure to soap xml structure,
> //this operation will construct SoapEnvelope,SoapBody,SoapFault instead of
> //regular OmElement
> StAXSOAPModelBuilder stAXSOAPModelBuilder = new StAXSOAPModelBuilder(soapEnvelope.getXMLStreamReader(), null);
> return stAXSOAPModelBuilder.getSOAPEnvelope();
> ...
> }
> 2) jettison 1.2 has cool feature called setIgnoreNamespaces which allows to use json formatter with any xml.
> We use the these builders and formatters successfully with JSON/badgerfish request and pure JSON response.
