[Mapserver-users] WMS requests.

[Bob Basques]

All,

While puttering with WMS functionality and MapServer.

I got a valid getCapabilities request to work ok, the XML stream comes 
back out real nicely, but when I try to run a GetMap request, I get a 
LAYER error back to the effect of :

    <?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?>
    <!DOCTYPE ServiceExceptionReport SYSTEM
    "http://schemas.opengis.net/wms/1.1.1/WMS_exception_1_1_1.dtd">
    <ServiceExceptionReport version="1.1.0">
    <ServiceException code="LayerNotDefined">
    msWMSLoadGetMapParams(): WMS server error. Invalid layer(s) given in
    the LAYERS parameter.
    </ServiceException>
    </ServiceExceptionReport>

I think it has to do with how I have my LAYERs defined.  Would a DEFAULT 
setting on all layers mess up the WMS output for example?  See my 
Mapfile below,  I have different sets of resolutiuon for each zoom 
range, shouldn't just the topmost be used for a default Map Generation 
(if I read the WMS how-to correctly) require only the top level Zoom 
values, regardless of whether the other LAYERS are set to Default.  I 
don't have any overlap (I don't think) in the LAYER definitions.

The Images output in non-WMS just fine BTW.

Thanks for any insight here.
