--------------------------------------------------------------------
Other than above MessageReceiver limitation current JSON support perform number
of extra XML/JSON conventions in both client and server sides in order to match
with existing Axis2 architecture. The proper solution would be
serialize/deserialize JSON to Java objects and back again directly but this
required some refactoring , google-gson [1] can be a good framework for this
propose with it's performance and streaming support.
BTW as a short term solution we can include your modification to work with
RPCMessageReceivers. BTW it's bit of difficult task to review raw source files
instead can you please provide your modification as a svn patch for Axis2
trunk. It Would be great if you can provide a unit test for this too .

> Key: AXIS2-5158
> URL: https://issues.apache.org/jira/browse/AXIS2-5158
> Project: Axis2
> Issue Type: Improvement
> Components: json
> Affects Versions: 1.6.1
> Reporter: Paul Hodchenkov
> Attachments: AbstractJSONBuilder.java,
> AbstractJSONMessageFormatter.java, ExtendedMappedXMLStreamWriter.java,
> JSONBadgerfishBuilder.java, JSONBadgerfishMessageFormatter.java,

> RawXMLInOutMessageReceiver can be only used in JSON services 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 my 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 JSON response.
