title: JSP request object has no parameters
body: <p>I have a JSP file, create.jsp, which receives a POST request from an Ext grid containing a data parameter. Firebug displays a POST like this:</p>
  
  <pre><code>{"data":{"a":"","b":"","c":""}}
  </code></pre>
  
  <p>When I try to retrieve the data from the request object in create.jsp using this method,</p>
  
  <pre><code>request.getParameter("data");
  </code></pre>
  
  <p>it returns null. In fact the request object contains no parameters or attributes.</p>
  
  <p>I've tested create.jsp with a POST that contains xaction:read and then the request.getParameter("xaction") returns "read", as expected.</p>
