Re: [geowebcache-users] Make tiles for several layers in same resolution/scale steps?

[rt90 <la...@gm...>]

Hi Arne and thanks for your reply.

My geowebcache.xml doesn't validate but this error I can't resolve(it
doesn't seem like it should argue with the schema) and GeoServer appears to
accept it anyway, though it complains about it just as validome's validator
does: "Can not find declaration of element 'gwcConfiguration'.". 
http://old.nabble.com/file/p28891004/geowebcache.xml geowebcache.xml 

I remade it with
http://geowebcache.org/trac/browser/tags/1.2.1/geowebcache/src/main/resources/geowebcache.xml
as base, and have attempted to make one of the layers work(be identical with
GeoServers WMS version of that layer) with OL so far
(graven:kyrkvagar_sw99tm). 

It appears to work okay in the gwc demo, and features appear to be where
they are when geoserver's wms service is used directly. I see that it sets
the bounds of the OL map to the gridSet's extent, which in this case is the
reference system's extent (though only a tiny portion of it is used by the
layers),
but when I set the OL map's bounds to the system's extent, and then
zoomTo(layer's bounds), nothing is shown, even if the coordinates of the
window indicate that things should be shown.

If I set the bounds of the map to the layer's bounds, and set scales : the
scales specified in geowebcache.xml, the same thing happens as when I use
the resolutions array the gwc demo makes (which corresponds to said scales),
i.e the geoserver WMS version of the layer works ok, but the gwc one 'jumps
about' the place a little (thirty meters up, down, to the side depending on
the current scale). Its features appear to be a little 'cut in the corners'
too. 
(Much the same errors as when I used the previous geowebcache.xml and did
not use the resolutions array the gwc demo made)

Could be primarily an OpenLayers problem, but do tell if the xml I currently
use appears appropriate.
