Hi Keith,
I’m using axis2-1.6. I have added message formatter and message builder entries in axis2.xml. I simply want the version service to return response in JSON format. But I'm always getting in xml format. Please help me. Basically I'm trying to build REST+JSON webservice using axis2

JSON can only be used with RawXML message receivers, and not any other message receivers. Also note that the outermost element in the payload of the soap envelope should not have any namespace qualification of namespace declarations. Elements inside that wrapper element can have namespaces.

Hi keith,

I have created a simple webservice which takes the json and return it by appending a string to it.

I am sending a very simple and clean json.
And i expect axis2 should recognised it as
application/json but it is treating it as
application/json/badgerfish.
I/O {log}

If i want to support only one type of json message like application/json
then what should i do. (if i remove badgerfish from messageformatter and messagebuilder then content type becomes
application/xml)

Is there any way?

Hi Keith, thanx for prompt reply.
No it ...

Hi Keith, thanx for prompt reply.
No it did not work for me.
How ever i will brief you what am I doing:
1. Have hosted a Axis2 web service from Axis user guide code.
2. Added message formatters and builders at server side.
2. Wrote a JSON client as below:

private OMElement createEnvelope3() throws Exception {
String input = "<twoWayOneParameterEcho><toEcho>Test Me!</toEcho></twoWayOneParameterEcho>";
return AXIOMUtil.stringToOM(input);
}

public void testdoEchoOM() throws Exception{
EndpointReference targetEPR = new EndpointReference(
"http://localhost:1111/axis2/services/SampleService");
OMElement payload = createEnvelope3();
Options options = new Options();
options.setTo(targetEPR);
options.setProperty(Constants.Configuration.MESSAGE_TYPE, "application/json");
options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
options.setProperty(Constants.Configuration.HTTP_METHOD, Constants.Configuration.HTTP_METHOD_POST);
File configFile =
new File("D:\\Kedar\\OpenSourceProjects\\Axis2-1.4.1\\modules\\json\\test-resources\\axis2.xml");
ConfigurationContext clientConfigurationContext = ConfigurationContextFactory
.createConfigurationContextFromFileSystem(null, configFile
.getAbsolutePath());
ServiceClient sender = new ServiceClient(clientConfigurationContext, null);
options.setAction(null);
sender.setOptions(options);
options.setTo(targetEPR);
OMElement result = sender.sendReceive(payload);
result.serialize(System.out);
// OMElement ele = (OMElement)result.getFirstOMChild();
// System.out.println(ele.getText());
}

----------------------------------------------
I need to do following:
1. Host Web Services (w/ Axis2) for SOAP/JSON/XML RPC.
2. Build Automated Client code for each one of the types above.
Kindly guide me in correct direction as I am finding bit lost out here with Axis2.

This error occured because Axis2 expected your request to be namespace qualified, but it was not.

One solution is to make sure your request honour the namespace expected by Axis2.

The other might be to add the following parameter to your services.xml. (I did not test this, but theoretically it should work)
<schema elementFormDefaultQualified="false"/>

Please let me know whether this worked for you.

Hi Keith,

I have an Axis2 embedded in my war file. But, I would like to enable json response for my services.

Thanks in advance and I hope for your response.
