Retrieving Object Names from a WEBI report

Hello,

I have to couple of Webi reports assigned to an universe. Can anyone tell me if there is a option to get the different universe objects, which are used in each Webi report query via JSP. I couldn't find a helpful method in the BusinessObjects Enterprise Web Services API, which would prodive this function.

Please provide steps to follow how could I get these used objects.

Thanks in advance,

David
