Hi Rajith,
Thanks, the error got resolved after using application/xml as messageType.
However, I am not getting a SOAP payload as the response as I got earlier.
Here are the two responses I got:
1. <property name="messageType" value="text/xml" scope="axis2"
type="STRING"/> with JsonBuilder and JsonFormatter
HTTP/1.1 200 OK
Host: localhost:8283
SOAPAction:
Content-Type: text/xml; charset=UTF-8
Accept: */*
Date: Sun, 18 Dec 2016 19:15:43 GMT
Transfer-Encoding: chunked
<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";>
<soapenv:Body>
* <jsonObject>*
* <hello>world</hello>*
* </jsonObject>*
</soapenv:Body>
</soapenv:Envelope>
2. <property name="messageType" value="application/xml" scope="axis2"
type="STRING"/> with JsonStreamBuilder and JsonStreamFormatter
HTTP/1.1 200 OK
Host: localhost:8280
SOAPAction:
Content-Type: application/xml; charset=UTF-8
Accept: */*
Date: Mon, 19 Dec 2016 06:40:36 GMT
Transfer-Encoding: chunked
*<jsonObject>*
* <hello>world</hello>*
*</jsonObject>*
Thanks!
