[udig-devel] Unable to connect to WFS server

[Jesse Eichar]

Hi Fabio,

I have spent the last three weeks working on the WFS client as well  
as interoperability with Geoserver and during that time I found a  
number of bugs in both.  We are releasing uDig 1.1.RC3 early next  
week which has the issue you refer to here fixed.  For a quicker fix  
you can download a nightly build and use that.  The nightly builds  
are quite stable on have all the WFS fixes that I have made.  A word  
of warning though.  Geoserver 1.3.2 still has a number of bugs so for  
the best results you will want to replace the gt2-main.jar, gt2- 
wfs.jar and the gt2-postgis.jar with the latest from the 2.2.x  
geotools branch.  But by the look of your FeatureType schema you  
should have to do that.

Cheers,
Jesse
