where to find jar file for com.sap.portal.favorites?

Hi,

I am trying to develop a custom desktop for SAP portal in which I want to show portal favorites on the landing page.

I also want to allow the user to add delete favorites from the custom desktop.

I found some information about an interface here: IFavoritesProvider

but I am unable to find the jar file for this interface.

Can anyone please provide me the path for the jar file which can be downloaded from the portal?

Thanks

Regards
