Problem with shape file rendering

[Benoît Andrieu]

Oh shit !!

You're right !

By not providing a bounding box in the url, I think that mapserver is doing 
a mistake and takes the coordinates of the extent present in the map file 
and converts them into the srs of the request !
So by simply puting -180,-90,180,90 in the url as the bounding box, I now 
see my points !!!!

Really sorry for those unnecessary emails !

Thank you for having helped me ! ;)

Hi,

This is mostly guessing, but could it be that there is some conflict due to 
that you are using epsg:4326 in your request but mapfile extents are in some 
other projection?  What happens if you change the SRS in the request to suit 
the map level projection?              Of course it must be added to wms_srs 
list first.

Given all this, I first tried to render this with a web browser by writing 
directly my request :
http://acquisitiontest/CGI/bin/mapserv.exe?request=GetMap&map=C:/temp/bch/Shell.map&request=GetMap&layers=Vector&srs=EPSG:4326&version=1.1.1&styles=
By not giving the extent nor width and height, I am expecting to take the 
full bounding box of the map file as width and height. I am already doing 
this for raster layers so I won't be surprised to make it work for shape 
files.

But, unfortunately, the result  remains empty whatever I try.

So, I remembered to use the shp2img to make a render and there I have a 
correct result.
