Hi Bernd,
I just tried to to a describefeaturetype against your server and got the
following error:
org.geotools.data.DataSourceException:
FeatureOfInterest1_iSPACE001 schema not available
FeatureOfInterest1_iSPACE001 schema not available
Could not type null as:null
My guess is there is some issue with the feature type yoru data store is
creating. If you can turn on verbose exceptions on your server I can
probably get a better idea where exactly the problem is.
