Thanks everyone for responding.
Jody, does your work today mean that in the near future it should be ok,
and hence I wouldn't need to add it to the WKT (because I'm not sure how
to do it)?
Do you think that this could be related to the sporadic results I'm
getting when trying to view a map or could it be something completely
different? It's strange... Sometimes only point data will work, other
times no points will show up on the map but lines and polygons will work
fine (even after a few refreshes). If I go into Geoserver and add a new
point feature type, points will work again, but then either lines or
polygons (or both) generally wont. I get the same results using udig
with geoserver.
