title: Liferay REST web service API
body: <p><br/>
  I'm trying to implement REST service in a liferay portlet. Found no way other than using JSON web services in liferay. I don't need to implement web services to interact with the database directly, meaning I dont want to build services to use Json web service. Is there anyway to implement REST web services in a liferay portlet without involving service building, more like a custom web service? Also provide any examples available if possible.<br/> Thanks in advance. </p>
