[mapserver-users] RE: Corrupted zipped shapefiles from WFS

[Keith Moss]

Hi Jeff,
 
Do you still have any of those zip files that you created? We'd be keen to take a look at them and see how they compare to the ones that we're generating.
 
I've attached a test case using an inline feature (as Andreas suggested) - is there any chance you might be able to try it on your Windows box and send us the resulting zip file?
 
cheers

Hi Keith, 

I know for a similar issue I created a small test case posted to a 
ticket last week 
(http://trac.osgeo.org/mapserver/ticket/3751#comment:21) and in that 
case I was able to output a valid zip archive of a shapefile through a 
WFS GetFeature request on Windows.  If I remember correctly I had to use 
MapServer trunk to get this to work properly. 

Honestly I didn't dive far into if the zips were valid or not (come to 
think of it, I was always using 7-zip to open them as well, which worked).
