Handling Header data coming from jsp page as Ajax request

Suppose we have incoming request from Liferay JSP form in Header part. And if request is an ajax request the we will create a serverResource method in Controller.

Step 1.  Add this in controller

@Override
    public void serveResource(ResourceRequest resourceRequest, ResourceResponse resourceResponse) throws IOException, PortletException {
       
HttpServletRequest request = PortalUtil.getHttpServletRequest(resourceRequest);
String methodName = request.getHeader("methodName");

 log.info("serveResource for OfferPortlet called with methodName="+ methodName);
  if (null == methodName)
{
 String msg =
 "No methodName parameter passed to OffermanagementPortlet.serveResource!";
  NullPointerException e = new NullPointerException(msg);
  log.error(msg,e);
  throw e;
}

//You can add your rest of code
super.serveResource(resourceRequest, resourceResponse);
}
