Note:This code is tested only in WebSphere Portal and i am not sure if it will work in the same way in any other standard compliant Portlet Container.
private HttpServletRequest getHttpServletRequest(PortletRequest request){
HttpServletRequest httpServletRequest = (HttpServletRequest)request;
while(httpServletRequest instanceof HttpServletRequestWrapper){
HttpServletRequestWrapper httpServletRequestWrapper =
(HttpServletRequestWrapper)httpServletRequest;
System.out.println("HttpServletRequestWrapper " + httpServletRequestWrapper);
httpServletRequest = (HttpServletRequest)httpServletRequestWrapper.getRequest();
}
return httpServletRequest;
}
The
getHttpServletRequest()
method takes PortletRequest
method and first casts it into the HttpServletRequest
object and then checks if its object of HttpServletRequestWrapper
type if yes tries to get the wrapped object by calling its getRequest()
method, it does this iteratively until it finds the HttpServletRequest
object that is not instanceof HttpServletRequestWrapper

This is output that i see when i call

method of my sample portlet

hey
thanks. very nice post.it helped me a lot.thanks again
See my article "Passing query parameters to JSR-286 portlets" here.
I know this is a supported way to do it. The solution presented here depends on a particular implementation which may change in the future, i.e. no guarantees.
Thanks for info....
