Now, GeoWebCache works great! I tried to use predefined scales, but it didn't work. Maybe I missed one parameter? I tried with the "scaleDenominators" property.
So, I defined the right resolutions, according the scales defined in my OpenLayers application. To find these resolutions, I used the getResolutionForZoom() method. Then, I put the founded resolutions into the GeoWebCache configuration file. The further problem I encountered was the extent problem. In my GeoWebCache configuration file, I put the maximal extent of the used projection (EPSG:2154), while in my OpenLayers map, I used an other maximal extent. I solved this issue by defining the map extent in my OpenLayers map like the one in my GeoWebCache configuration file. Then, I put a restricted extent in my OpenLayers map, with my previous maximal extent. This way, I keep the previous restricted extent, and I used the right extent to generate the tile (according to GeoWeCache). The only persisting problem is, if I seed tiles in GeoWebCache, I will seed them for the entire extent of my projection! I tried to seed them with a specific extent, but it didn't work. I think, maybe the specified extent was wrong. I don't know how calculate the right bounds for my projection and 256*256 tiles. Could anyone explain this? It should exist a mathematic formula? I've got two others issues: - it would be great to use my personal projection for all the GeoServer layers in the GeoWebCache configuration panel. At this moment, I must specify each layer in the GeoWebCache configuration file, and then, this is detected in the configuration panel. Is there a tip allowing GeoWebCache to get all the WMS GeoServer layers, like for the 4326 projection? - I need to keep some informations from WMS GeoServer layers, like the keywords. The problem is that GeoWebCache don't keep these informations when it create the new WMS layers. I tried to manually put keywords in the GeoWebCache configuration file, but it didn't work. Is there a way to that? I hope these informations would help someone once, and I would get some extra tips! ;) Geoffrey On Wed, 07 Sep 2011 15:06:01 +0200, Stephen V.
