I have a web page that uses MS Office Web Components connecting to an Analysis Services cube. We recently upgraded to SQL Server 2005 so I need to update the way that OWC connects to the AS cube. I followed the steps at http://www.microsoft.com/technet/prodtechnol/sql/2005/httpasws.mspx
(twice just to be sure) and changed my connection string in the web page to "Provider=MSOLAP;Data Source=http://myserver/olap/msmdpump.dll;Initial
Catalog=MyMDdb". I could then bring up the pages on the server (after installing owc11.exe) but the clients failed with the OWC error "The query could not be processed: The data provider didn't supply any further error information". This helpful message caused me to install the Microsoft OLE DB Provider for Analysis Services 9.0 on the client machine (though I wouldn't expect that this would change anything since data access should be through http).
After this install on the client, the pages with OWC on my server return (to the client box) the OWC error "The query could not be processed: XML parsing failed at line 1, column 0: A document must contain exactly one root element. ."
Is there some collection of settings I need to establish in order for this to work? Any help would be very much appreciated.
