Report Builder url unable to open

Hi All,

I configured database in SharePoint integrated mode using Reporting Services Configuration Manager.  i'm trying to open Report manager url (http://<servername>:80/Reports) getting below error.

"This operation is not supported on a report server that is configured to run in SharePoint integrated mode. (rsOperationNotSupportedSharePointMode)"

Any body having experienced with this issue, please share...

Thanks
