Re: [udig-users] Shapefiles on a network drive fail
The IndexedShapefile can in theory do this... But obviously a bug has been introduced. I will try to find the time to fix this but I am just settling into a new job so it may be a little tricky.

I've clipped out the log to get the error message. It's an access denied

The file can be loaded by the wizard, but then fails at rendering.

I submitted my log file to the bug reporting system just now, if you
want to look at it in more detail.

Y:\ is a mapped network drive.

Thanks,
Angus.

Subject: Re: [udig-users] Shapefiles on a network drive fail

Hi Carr,

For a while we used different shapefile reading code when something is
located on a network share (since the windows "memory mapped" idea does not work when working on a network shared file). That is the reason why 
the index files are not being used on network share.

What kind of errors are you getting?
Jody


Hi, List.

Has anyone else had errors with getting non-local files to read

properly?


I have a file WTRSHTER.shp (and all it's extra bits) which I cannot
read on the network drive (YJ but which when I copy it to a local
drive, it reads fine.

Has anyone else had such a problem?

Udig downloaded today, so v1.1-RC14

The file can be read quite happily by other GIS products, in either
location.

UDig creates the index files .fix and .qix in the directory when I
copy it locally, and does not on the network drive.

I presume that the creation of these spatial index files is much of
the problem. Is there any way to read from a write-only directory?
