HttpServletRequest httpRequest = (HttpServletRequest) (FacesContext
.getCurrentInstance().getExternalContext().getRequestMap()
.get("com.liferay.portal.kernel.servlet.PortletServletRequest"));

Jagat Pandya:

HttpServletRequest httpRequest = (HttpServletRequest) (FacesContext
.getCurrentInstance().getExternalContext().getRequestMap()
.get("com.liferay.portal.kernel.servlet.PortletServletRequest"));

Wrong wrong wrong.

First, the OP's code fails because:

FacesContext fc = FacesContext.getCurrentInstance();
HttpServletRequest request = (HttpServletRequest) fc.getExternalContext().getRequest();

The request instance is a PortletRequest, not an HttpServletRequest. Cast it to a PortletRequest and you're fine.

Second, if you need the original HttpServletRequest (which I highly doubt because no one in the portlet world typically needs this request), you use the com.liferay.portal.util.PortalUtil.getHttpServletRequest(PortletRequest) to access it.

Do not attempt Jagat's 'back door' access because it may break in the future, where the API will be maintained.
