[OpenLayers-Users] OpenLayers and GeoWebCache on GeoServer

[Dipl. Inf. Carsten Eider]

Hi Tobias,

thank you for your hints. But i cannot get it running.
I think my problem has to do with  the origin and size of my
gwc-data,but i cannot grab it where to start.

So my gwc-configuration(layer iis:Luftbilder) is on
http://tc.agroconnect.fh-bingen.de/geoserver211/gwc/service/wmts?REQUEST=getcapabilities

I have setup da demo under http://lw.igreen.fh-bingen.de/igg/olc.html

My errors (see firebug-console):
<ExceptionReport version="1.1.0"
xsi:schemaLocation="http://www.opengis.net/ows/1.1
http://geowebcache.org/schema/ows/1.1.0/owsExceptionReport.xsd"><Exception
exceptionCode="TileOutOfRange"
locator="TILECOLUMN"><ExceptionText>Column 0 is out of range, min: 8
max:8</ExceptionText></Exception></ExceptionReport>

Any ideas?

TIA Carsten
