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);
}

Liferay Dynamic Query API

Liferay Dynamic Query API  -Liferay Dynamic Query API is an elegant feature in Liferay portlet development. -Dynamic Query API can only perform read operations against database. These we will use specially to provide search operations against database. -Dynamic Query API is independent feature and we can implement anywhere in the development like we can implement in JSP pages, Portlet Action Classes and service implementation classes.
