[udig-devel] R: Writing Data in GeoServer WFS Data Store

[Jesse Eichar]

So a couple of things.

1.  Make sure that you have one of the Geoserver 1.4.x versions  
installed
2.  Replace the gt2-main and the gt2-postgis jars with:
	- http://lists.refractions.net/m2/org/geotools/gt2-main/2.2.1- 
SNAPSHOT/gt2-main-2.2.1-SNAPSHOT.jar
	- http://lists.refractions.net/m2/org/geotools/gt2-postgis/2.2.1- 
SNAPSHOT/gt2-postgis-2.2.1-SNAPSHOT.jar

That should get the Geoserver up to date so that it will work  
correctly with uDig.  The reason for this is because Cory just made  
some fixes so that postgis is "smarter".

If you want uDig to be able to directly modify the postgis table you  
may need to replace the gt2-postgis and gt2-main jars in the udig 
\eclipse\plugins\net.refractions.udig.libs_1.1.0\lib directory  
(assuming you are on windows) with the same jars mentioned above.   
uDig and Geoserver use the same jars for accessing postgis.  So if  
you can add/edit features directly against the postgis using udig but  
not routed through a postGIS then you know that the Geoserver is not  
using the latest jars (which it isn't).

On that point Geoserver 1.4.something else is coming out soon and  
will have these fixes in it.
