2PortletRequest portletRequest = (PortletRequest) externalContext.getRequest();
3HttpServletRequest httpServletRequest = PortalUtil.getHttpServletRequest(portletRequest);

I tried this, and I got the following error:

117:38:37,227 ERROR [STDERR] java.lang.RuntimeException: Unable to get the portlet request from com.icesoft.faces.webapp.http.portlet.PortletExternalContext$4

From looking at the java.lang.RuntimeException, my best guess is that you are using ICEfaces 1.8 and not ICEfaces 2/3.

The problem is that ICEfaces 1.8 does not utilize the Portlet 2.0 RESOURCE_PHASE (ResourceRequest) for Ajax. Instead, ajax requests are made from the browser directly to the ICEfaces servlet. So the basic problem is that there isn't an underlying PortletRequest object with ICEfaces 1.8 Ajax.

Are you able to upgrade to ICEfaces 3.2 and Liferay Faces Bridge? If not, then what do you need to get from the underlying HttpServletRequest? Depending on what you need, there *might* be a way to get what you are looking for.
