Fetch From UWL to WD view :UWL Exception Logged in users context or session

Question

Hi,
We have a requirement in which , we need to fetch all UWL Items and need to display these in a webdynpro view.
We tried based on this link [Custom UWL|http://searchsap.techtarget.com/tip/0,289483,sid21_gci1240907,00.html].
Coding What I have Tried is
       IWDClientUser user1 = WDClientUser.getLoggedInClientUser();
            IUser epUser1 =user1.getSAPUser();
            IPortalRuntimeResources runtimeResources = PortalRuntime.getRuntimeResources();
            wdComponentAPI.getMessageManager().reportSuccess("Version "+PortalRuntime.getVersion());
            IUWLService uwlService = (IUWLService) runtimeResources.getService(IUWLService.ALIAS_KEY);
            uwlService = (IUWLService) runtimeResources.getService(IUWLService.ALIAS_KEY);
            wdComponentAPI.getMessageManager().reportSuccess("6");
            UWLContext uwlContext = new UWLContext();
            uwlContext.setUser(epUser1);
            wdComponentAPI.getMessageManager().reportSuccess(" UML Context"+uwlContext.getUserId());     
            wdComponentAPI.getMessageManager().reportSuccess("9");
            IUWLSession uwlSess=uwlService.beginSession(uwlContext, 6000);
            uwlContext.setSession(uwlSess);
            wdComponentAPI.getMessageManager().reportSuccess(" UML Session"+uwlSess.getUser().getUniqueID());
            IUWLItemManager itemManager = uwlService.getItemManager(uwlContext);
            wdComponentAPI.getMessageManager().reportSuccess("Item manager"+itemManager.getItems(uwlContext,null,null));
            QueryResult result = itemManager.getItems(uwlContext,null,null);
            wdComponentAPI.getMessageManager().reportSuccess("12");
            int size = result.getTotalNumberOfItems();
            ItemCollection collection = result.getItems();
            java.util.List list = collection.list();
            Item item = null;
            Date date = null;
            String subject = null;
            for(int i = 0; i < 5; i++)
            if(!(i > (size -1)))
            item = collection.get(i);
            date = item.getDueDate();
            subject = item.getSubject();
            wdComponentAPI.getMessageManager().reportSuccess("item "+item);
            wdComponentAPI.getMessageManager().reportSuccess("date "+date);
            wdComponentAPI.getMessageManager().reportSuccess("subject "+subject);
But I am getting the Exception
Exp: com.sap.netweaver.bc.uwl.UWLException: Wed May 14 11:20:29 IST 2008 (Default) Logged in users context or session doesnt exist
in the line
QueryResult result = itemManager.getItems(uwlContext,null,null);
But according to first mentioned link the user is getting through Portal Request Object. In webdynpro, we were not able to get Portal request object. So we  are getting the current user from UME .
So we are getting the exception.
Can anybody help me
Thanks and Regards
Smitha
