Sagara Gunathunga commented on AXIS2-5158:
-------------------------------------------
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. It's bit of difficult task to review raw source files
instead can you please provide your modification as a svn patch file for Axis2
trunk. It Would be great if you can provide a unit test for this too .

> Project: Axis2
> Issue Type: Improvement
> Components: json
> Affects Versions: 1.6.1
> Reporter: Paul Hodchenkov
> Attachments: AbstractJSONBuilder.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.
