Couldn't access Webservice with client code using Apache axis2 And restful webservice

Question

I created an restful webservices using Axis2. I deployed .aar file on server, when i am trying to access that webservice with url through axi2 services its showing the error from java page which i have used in webservice like :

<getActivitiesResponse>
    <statusCode>300</statusCode>
    <statusMessage>NO_RESULTS_FOUND</statusMessage>
</getActivitiesResponse>

But when i am trying to access with some client code that is trying to hit the url with request parameters its saying:

  java.io.IOException: Server returned HTTP response code: 500 for URL

I am using OMElement for request and response creation

I figured out. Actually I need to configure the axis2.xml file:

In Message Formatter this should be added

<messageFormatter contentType="application/json"
        class="org.apache.axis2.json.JSONMessageFormatter" />
</messageFormatters>

And in Message Builders

<messageBuilder contentType="application/json"
        class="org.apache.axis2.json.JSONOMBuilder" />
</messageBuilders>

This solved my problem. Hope it will help others.
