The LocationMap fails to find files that have spaces embedded in the URL.  For 
instance in my case, it will find 

http://10.222.67.105/open/eav4x/Inventory/System%20Identification%20Report.pdf

But fails to find it as

http://10.222.67.105/open/eav4x/Inventory/System Identification Report.pdf. 

Incidentally, for information on resolving to PDF files please see
