Re: [geowebcache-users] Error Calling layers from Google maps

[Arne K. <ak...@op...>]

Hi Surendran,

the most likely cause is a minor misspelling of the "layer-name" you use 
in the GTileLayer constructor (landuse:DwellingsWithBasements) and what 
the actual name of the layer is according to GeoWebCache.

In the same window, when GWC is starting, it should list all the layers 
it is loading. Compare with the names there?
