uDig and MapServer WFS

Reply Threaded

Some javascript/style in this post has been disabled (why?)

Dear All,

I’m trying to use uDig in connection with MapServer’s WFS capability. I have set up a .map file that contains all the information needed for a WFS according to the instructions in the MapServer user guide and can get the XML in response to a get capabilities:

http://localhost/cgi-bin/mapserv.exe?map=/ms4w/apps/labuan/mapfiles/labuan_wfs.map&SERVICE=wfs&VERSION=1.0.0&REQUEST=GetCapabilities

But if I open the service using uDig although I can select layers and they apper in the layers view, no data is displayed and the table view contains 0 records and the layer count is 0.

If I use the same map file and open the layers as a WMS then I can see the data

Does anybody have any suggestion regarding what I’m doing wrong?

Thanks

Graham

Re: uDig and MapServer WFS

Hi,

I have found that a uDig/Mapserver combination is especially picky on data
that has no clear extent. Try explicitely mentioning the extent, by
including
"ows_extent" "xmin ymin xmax ymax"
or
"wfs_extent" "xmin ymin xmax ymax"
in the METADATA section of each LAYER definition

Hope this helps,
