Dear Experts

We have Integrated our ADF application into Webcenter portal.

in ADF application we have a page ,which has golink for downloading PDF.

When we click on on that golink it will open a new tab with PDF rendering.for this we wrote a servlet to show PDF in new TAB.

so far so good.after integration with webcenter,when we click on that golink new tab is opening but it redirecting to login page for authentication.

we entered username and password then we are getting authorization exception.

we understood that security(Authentication and Authorization is not applied for the above servlet).

Can anyone point me How and where to configure security for this servlet.
