Hi, I made a new Windows default installation with Tomcat and Geoserver war file and I managed to get similar errors than you have reported in some of your old mails. I also managed to make GWC to work with my own layer and to use another cache directory than the default one.
What I did was - After installation I changed the default cache dir by editing the web.xml file by adding <context-param> <param-name>GEOWEBCACHE_CACHE_DIR</param-name> <param-name>d:\my_cache_dir</param-name> </context-param> Restarting Tomcat at this phase was giving errors like this: 2010-11-22 12:15:03,825 ERROR [layer.TileLayerDispatcher] - Configuration /usr/lib/jvm/Geoserver/geoserver/webapps/geoserver/../resources contained no layers. Adding a valid geowebcache.xml file into the root of d:\my_cache_dir and restarting Tomcat wiped away those errors, my own layer appeared into the gwc demo layer list, OpenLayers preview started to work and cache started to collect tiles. Thus in my case two steps were enough: 1) set the GEOWEBCACHE_CACHE_DIR 2) install a valid geowebcache.xml into GEOWEBCACHE_CACHE_DIR I did not try to change the port into :8090 as you are having, that can cause some other problems for you. I think that the error message which contains "/usr/lib/jvm/Geoserver/geoserver/webapps/geoserver/../resources" is a bit confusing for the user because there does not exist such directory of file. -Jukka Rahkonen- > -----Alkuperäinen viesti----- > Lähettäjä: Luís de Sousa [mailto:luis.a.de.so...@gmail.com] > Lähetetty: 23. marraskuuta 2010 12:20 > Vastaanottaja: Ryan Williams; geoserver-users@lists.sourceforge.net > Aihe: Re: [Geoserver-users] Help with GeoWebCache > > Hello Ryan, thank for your comment. > > As I wrote, I'm using Geoserver 2.0 and trying GWC with one of the > sample raster layers bundled with it, nurc:Arc_Sample.
