I have preexisting caches of maps that I would like to turn into a WMS. I am trying to implement this through Geoserver/Geowebcache. I tweaked the web.xml file to set the Geowebcache_Cache_Dir to the directory with the preexisting cache. I then put the appropriate information into geowebcache.xml and Geoserver can see the cache under Tile Layers, from here I can open it in OpenLayers, however, I can't ping the cache through a WMS call from arcgis or google earth. I checked the box for direct integration with Geoserver WMS but I still cannot seem to get external softwares to see the WMS. I checked fiddler and it seems to be hitting the tiles in openlayers through /geoserver/gwc/service/wms?blahblahblah. If I try to hit that WMS endpoint from anything else I get the ever so helpful error 400.

Does anyone know the proper method for building a WMS from a cache using this software?

  • Hard to answer without seeing your config file, is it set up to point the layer to your GeoServer Instance? Commented Oct 9, 2014 at 1:39
  • I'm running Opengeo Suite 4.1.1. I can give you all the steps I did to get where I currently am:Tweaked web.xml with <!--Added new GWC Directory--> <context-param> <param-name>GEOWEBCACHE_CACHE_DIR</param-name> <param-value>D:\Workspace\Cache\Converted_Cache</param-value> </context-param> Did this to point the cache dir at the folder location with the prebuilt cache (D:\Workspace\Cache\Converted_Cache) cache named “Cache_CADRG_WMS_ARC_Layers”. After reloading Geoserver it places the geowebcache.xml file in that directory. Commented Oct 9, 2014 at 14:08
  • I tweaked that geowebcache.xml with <wmsLayer> <name>Cache_CADRG_WMS_ARC_Layers</name> <mimeFormats> <string>image/gif</string> <string>image/jpeg</string> <string>image/png</string> <string>image/png8</string> </mimeFormats> <wmsUrl> <string>demo.opengeo.org/geoserver/wms</string> </wmsUrl> <!--wmsLayers>nurc:Img_Sample</wmsLayers--> </wmsLayer> This enabled the tileset to appear under Tile Layers.

  • Preview with JPEG in OpenLayers works well but trying to hit the endpoint with ArcGIS (localhost:8080/geoserver/wms?) it results in no love. Even with direct integration with GWC enabled and specifying TILED=true it still won't render the tiles in Arcgis/Google Earth etc. Commented Oct 9, 2014 at 14:15
  • Have you tried your WMS url with a http:// in front of it? YOu should post your actual Xml file in your question, makes it a lot easier .. Commented Oct 9, 2014 at 15:04

After going back through my questions I wanted to post an update to this that there was a bug at the time that prevented GWC from doing this. I talked directly with the Boundless folks about this at the time. I think it's been fixed since then but haven't tested it since. I ended up working around the issue with a set of cascaded WMSes.
