| On Windows using Geoserver 2.10 admin webinterface, try to create a Image Mosaic store by using the browse button and browse to whatever directory outside the GEOSERVER_DATA_DIR folder (be it on c: or d: or e , eg d:\data you will see in the webpage: file://D:\data when trying to save it as a store you will see an error message (see windowserror.jpg): Could not list layers for this store, an error occurred retrieving them. Failed to create reader from file://D:\data and hints is null Note that in 2.8 the same url's/paths just work: file://E:\luchtfotos2016 file://D:\data Funny thing is (see windowserror2.jpg) that browsing for a Shapefile store you will see the same funny file-URL's: file://C:\temp\provincies\provincies.shp but at least the creation of the store just works ![]() Maybe it has something to do with the types of datastore (which handle the URL's?) or maybe it has something to do that for a shapefile you point to a FILE and for a MosaicStore you point to a DIRECTORY? |
