Andreas Veithen commented on AXIS2-5158:
----------------------------------------
The code in Axis2 trunk now fully supports both Badgerfish and mapped JSON.
This works out of the box with data bindings, including POJO services.
To use mapped JSON, add a xmlToJsonNamespaceMap parameter to the service
configuration to define the mappings between XML and JSON namespaces, as shown
in the following sample:
<service name="POJOService" scope="application"
targetNamespace="http://example.org";>
<description>POJO Service</description>
<schema schemaNamespace="http://example.org"/>
<messageReceivers>
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only";
class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"/>
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out";
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
</messageReceivers>
<parameter name="ServiceClass">org.apache.axis2.json.POJOService</parameter>
<parameter name="xmlToJsonNamespaceMap">
<mapping xmlNamespace="http://example.org"; jsonNamespace=""/>
</parameter>
</service>
There are a couple more things to be done before the issue can be closed:
* Add/update documentation.
* The new JSON code relies on the feature introduced by AXIOM-399, but that
feature doesn't interact in an optimal way with the optimizations described in
AXIOM-282.
* Check that the feature can be used with Synapse (and maybe add a new sample).

> Project: Axis2
> Issue Type: Improvement
> Components: json
> Affects Versions: 1.6.1
> Reporter: Paul Hodchenkov
> Assignee: Andreas Veithen
> 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.
