Thanks for the response - I've been tied up with other things a bit. After ensuring that the geometry column WAS registered (a number of my experiments may have meant this wasn't the case), I'm instead getting a:
java.lang.OutOfMemoryError: Java heap space Java heap space Is this reasonably likely with what I'm trying to do, or does it tell me that there's still something wrong? The request is: http://localhost:8080/geoserver/wfs?request=GetFeature&typeName=hy-p:Watercourse&maxFeatures=1 I've attempted to increase the heap space as follows: w...@will-desktop:~$ sudo bash [sudo] password for will: r...@will-desktop:~# export CATALINA_OPTS="-Xmx512m -Xms512m" r...@will-desktop:~# service tomcat6 restart ... [ OK ] But I still get the error. I include the above because it is possible that what I've done will not have the desired effect. Tomcat is running in an Ubuntu virtual machine which has 1GB RAM allocated. Any more thoughts? Thanks for the help.

For example, can you use the GeoServer GUI to add a new data store for your database, publish the rivers_polyline layer, and make a WFS GML 3.1 request against it? This will help us diagnose whether it is the simple feature layer or the app-schema layer that is having problems. - When you view the table as a GML 3.1 (WFS 1.1) simple feature, are the geometries correctly encoded? - Are all your geometries in this column the same type? I don't think GeoServer will like a mix. - Is this geometry column registered in geometry_columns? Bad Things Will Happen if it is not correctly registered. Kind regards, Ben.
