I forgot to mention the json builders and formatters, see below.
Also, the json support works by the content-type header flag so be
sure to set it from whatever http client you use:
curl -H "Content-Type: application/json"
<messageFormatters>
<messageFormatter contentType="application/x-www-form-urlencoded"
class="org.apache.axis2.transport.http.XFormURLEncodedFormatter"/>
<messageFormatter contentType="multipart/form-data"
class="org.apache.axis2.transport.http.MultipartFormDataFormatter"/>
<messageFormatter contentType="application/xml"
class="org.apache.axis2.transport.http.ApplicationXMLFormatter"/>
<messageFormatter contentType="text/xml"
class="org.apache.axis2.transport.http.SOAPMessageFormatter"/>
<messageFormatter contentType="application/soap+xml"
class="org.apache.axis2.transport.http.SOAPMessageFormatter"/>
<messageFormatter contentType="application/json"
class="org.apache.axis2.json.gson.JsonFormatter"/>
</messageFormatters>

<!-- Message Builders -->

<!--Following content type to builder mapping can be used to

<!--formats in Axis2. These message formats are expected to be
resolved based on the content type. -->
<messageBuilders>
<messageBuilder contentType="application/xml"
class="org.apache.axis2.builder.ApplicationXMLBuilder"/>
<messageBuilder contentType="application/x-www-form-urlencoded"
class="org.apache.axis2.builder.XFormURLEncodedBuilder"/>
<messageBuilder contentType="multipart/form-data"
class="org.apache.axis2.builder.MultipartFormDataBuilder"/>
<messageBuilder contentType="application/json"
class="org.apache.axis2.json.gson.JsonBuilder"/>
</messageBuilders>
