I want to say thanks to Debbie for her help. Wow this one was so
simple, but took a while to figure out. It turns out that if you have
the STATUS set to ON the WMS layer will not display. If you change the
STATUS to DEFAULT the WMS layer displays. Is a WMS layer suppose to
behave like this? It took me a while to figure this one out, so I hope
it saves someone else some time.
Thanks,
Brian

First, I'd try to get the WMS layer working all by itself, without
worrying about your other layers or projections. Once you have that
working, try to add in the other layers and projection parameters. As
for projections and WMS layers, I think you have to add the srs
parameter in the connection string e.g.:
&VERSION=1.1.0&REQUEST=GetMap&layers=world&SRS=epsg:4269" and then you
have to add in the projection object in the mapfile. PROJECTION
"init=epsg:4269"
END
The only other thing I notice in the mapfile is that
CONNECTIONTYPE WMS
comes AFTER the CONNECTION string. Perhaps it should go before? Not
sure if that makes a difference or not.
A question for you... have you seen my posts coming through the
mapserver discussion forum? I have been trying to post to the forum for
a couple of days and haven't seen my own posts.
Thanks,
Debbie

Thanks Debbie. I now see the image in my web browser via the connection
string
(http://www2.dmsolutions.ca/cgi-bin/mswms_gmap?VERSION=1.1.0&REQUEST=get
MAP&LAYERS=bathymetry,prov_bound,drain_fn&FORMAT=image/gif), but I still
don't get the image in my MapServer application. I think my problem may
be related to projections, because I don't get any error messages. It
almost seems like I may be getting a blank image from the WMS server. I
see my other layers in the mapfile, but not the WMS layer. How are
projections handled via the WMS Client Support?
I am trying to get DMSolutions Elevation/Bathymetry data to display.
According to the getCapabilities from that WMS Server the data is in
EPSG:42304. I essentially want the data to be projected to EPSG:4269
(NAD83 DD). Here is my mapfile: Am I using the projections incorrectly?
Or is there something else I am missing in my mapfile or connection
string?
Thanks,
Brian

Your WMS request is not formated correctly. For instance, in the layer
from DMSolutions, you are missing REQUEST=getmap:
http://www2.dmsolutions.ca/cgi-bin/mswms_gmap?VERSION=1.1.0&REQUEST=getM
AP&LAYERS=bathymetry&FORMAT=image/gif
Make sure that the URL for your WMS layers are working in a browser
before adding them to your mapfile. Also, I don't know what your other
layers are, but make sure that the order of your layers in your mapfile
is correct so that you aren't covering the WMS layer with opaque layers.

Hi MapServer WMS users,
I am new to the WMS feature of MapServer. I am trying to add a WMS
layer to my current mapserver application and I am not having any
success. I have read through the WMS Client HowTo and an old posted
message
(http://mapserver.gis.umn.edu/cgi-bin/wilma_hiliter/mapserver-users/0204
/msg00314.html) and neither seem to work for me. I am using
MapServer3.5 with WMS_Client Support.
When I insert the WMS layer into the map file all I see in the web
browser are my non-wms layers. None of the WMS layers seem to show up.
I have tried two different WMS layers; one from the Geography Network as
used in the old posted message and one by DMSoultions in the WMS HowTo.
My map file is attached below. Can anyone see any reason why the WMS
layers wouldn't be showing up in the web browser?
Thanks,
Brian
