check if user has particular role access in Java iView

Hello,

I have a link to a portal page as follows.

http://abc.com/SAPPortal/?NavigationTarget=/roles/PODemoRole/PODemo/PODemo_MSPlanIDDisplay?code=1

Now certain users have access to this page and certain users don’t. Within the portal this is not a problem cause, the page will not be displayed if the user does not have access to it. However if the same user who does not have access to this page clicks the above link externally to the portal, the page gets displayed. So it seems like the role check is not being done in this case.

Which means perhaps I have to do it in the java iview itself. But not sure how to do that. Can you suggest how I can get around this problem. Thanks.

Sunil
