Hi, that is strange: Also the getCapabilities-response lists 1.0.0 as valid (<ows:Parameter name="AcceptVersions"> <ows:Value>1.0.0</ows:Value> <ows:Value>1.1.0</ows:Value> </ows:Parameter>) i get a unknownHost exception, if i add &Version=1.0.0 to the URL. If i add Version 1.1.0 the host is found, but the name-property still is not present. Strange...
