javax.portlet.ResourceResponse reference in Action

[Gaurav Daga <to...@gmail.com>]

Hello All

What is the recommended way of getting ResourceResponse instance in the
action method of JSR 286 based Struts2 Portlet Action class? I'm using
following way :

ResourceResponse response =
(ResourceResponse)PortletActionContext.getResponse();

As PortletActionContext doesn't provide method to get ResourceResponse
instance. Am I missing something here?

*Thanks & Regards/ **सादर**,*

MG>ActtionContext is set to null as seen here in Jsr286Dispatcher (processEvent)
Jsr286Dispatcher::processEvent(EventRequest request, EventResponse response) throws PortletException, IOException 
{
ActionContext.setContext(null);
}
 
..later on Jsr286Dispatcher has override for createPortlerServletResponse..   
@Override
 protected PortletServletResponse createPortletServletResponse(PortletResponse response) 
{
        return new PortletServletResponseJSR286(response);
 }
