Dear all, I am having troubles to configure geowebcache integrated with geoserver 2.0.2. Geoserver is deployed in a Tomcat 6.0.20 in Linux Opensuse 11.1.
My first working wms request is this one: http://druidtest.gmv.es:8084/geoserver/wms?LAYERS=topp%3APO_CC_2007-2008&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&SRS=EPSG%3A4326&BBOX=-8.94,42,-8.428,42.512&WIDTH=256&HEIGHT=256 The gwc demo works for this layer: http://druidtest.gmv.es:8084/geoserver/gwc/demo/topp:PO_CC_2007-2008?gridSet=EPSG:4326&format=image/png. However, the following wms request (through gwc) fails: http://druidtest.gmv.es:8084/geoserver/gwc/service/wms?LAYERS=topp%3APO_CC_2007-2008&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&SRS=EPSG%3A4326&BBOX=-8.94,42,-8.428,42.512&WIDTH=256&HEIGHT=256&TILED=True The error obtained is: "400: Requested horizontal resolution: 0.001999999999999995 , best match: 0.001373291015625 exceeds 10% threshold. Perhaps the client is configured with an incorrect set of scales (resolutions), or the DPI setting is off compared to the one in GWC ?" I have checked the posts in the lists with similar problems, so I tried to solve it defining my custom configuration file with the resolution values that I got from the openlayers source code of the demo, assuming that these should be ok. I changed the bounds in the request for them to match as well: http://druidtest.gmv.es:8084/geoserver/gwc/service/wms?LAYERS=topp%3APO_CC_2007-2008&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&SRS=EPSG%3A4326&BBOX=-8.793,42.031,-8.029,42.816&WIDTH=256&HEIGHT=256&TILED=True This time I obtained this error: * 400: X,Y values for the tile index were calculated to be {243.49439999999998, 187.77742222222224} which had to be rounded to {243, 188} and exceeds the threshold of 10%. Perhaps the client is using the wrong origin ? The demo still works here with the new configured GridSubset: http://druidtest.gmv.es:8084/geoserver/gwc/demo/topp:PO_CC_2007-2008?gridSet=The%20Entire%20World&format=image/png Could somebody point me in the right direction?. Why should it work in the demos (OpenLayers) and not with a simple WMS query? I copy below the content of the geowebcache.xml config file. Thanks in advance.
