Axis2 Json web service

I have a SOAP WSDL web service running in Apache Axis2.

After looking in Apache site, I have found that it is possible to configure the web service to send and get Json request.

After changing the Axis2.xml file as told, I didn’t know how to proceed. I should get my respond as Json from Java code, while meantime the web service get and sends Soap requests..

Looking for some examples, ideas ..
