[mapguide-users] Raster problem

[Kenneth Skovhede, GEOGRAF A/S]

Does the "Failed to read schema" error produce entries in the MapGuide 
error.log?

On this page:
http://localhost/mapguide/mapagent/index.html

Click "Feature", then "DescribeSchema".
Fill out the "ResourceID" field with the path of your FeatureSource,
then click "Submit".

The resulting xml should tell you what went wrong, and if not, please
create a trac ticket, and attach the output xml to the ticket.

Regards, Kenneth Skovhede, GEOGRAF A/S
