title: Create a Webservice using PL-SQL that accepts JSON or XML type input parameters
body: <p>Basically I want to create a REST Web Service using PL-SQL in Oracle and following are my requirements</p>
  
  <ul>
  <li>It should accept string parameter. That string parameter could a JSON format string or XML data</li>
  <li>It should not accept any parameters on the URL. Rather parameters should be received using http request object.</li>
  <li>Web service should then able to read the input received and print the details. 
  For ex. A simple web service that receives name of the person in JSON or xml format and then prints back 'Hello ' || Name</li>
  </ul>
