We are trying to get information from a protal that is hosting the WO app, this is what I am using to try to do so.

What is the stack trace?

Isn't context already a WOServletContext (which is a subclass of WOContext)? Can you just do:
WOServletContext wosc = (WOServletContext) context; 

When I tried that it throws java.lang.ClassCastException

IPortletContext newFact = PortletContextFactory.createPortletContext(wosc.httpServletRequest (), wosc.httpServletResponse());
IPortletContext newFact = PortletContextFactory.createPortletContext(wosc.httpServletRequest (), wosc.httpServletResponse());
IPortletRequest newReq = newFact.getRequest();
IPortletUser portletUser = newFact.getUser();
String uName = portletUser.getUserName();

I thought that the context would have a request. Am I wrong? Do I need to create a request?
