You can certainly use multiple local and remote layers.
=20
Now that the PROJ problem is fixed, are you getting any errors? Is the =
layer simply not appearing? Is the layer turned on (STATUS ON isn't =
enough)?

Subject: RE: [Mapserver-users] WMS
Ed,
thanks for the quick answer. But the answer is: yes... As the WMS =
service from where I want to retrieve a layer, does for sure work as it =
has been implemented into another application, the problem can hardly be =
on this side. I think, something is wrong on the map-file side. As the =
BBox and other parameters are produced automatically by MapServer, the =
URL used in the CONNECTION line below should be correct...
Just to be sure: Can I have a map-file with multiple local layers, which =
are accessed normally, and in addition a couple of WMS layers, accessed =
as shown below? I was just wondering if MapServer would be capable of =
merging then two, three or four different images, as each WMS service =
sends its own image back. I know that I can overlay different requests =
and thus images using simple HTML code, but I am not so sure about the =
method I just wanted to implement. Stupid question? Hmmm...
Ciao,
Stefan

We don't know what your data are, so we can't tell whether the metadata =
(the projection in particular) are correct - you need to check that. =
You also need to be requesting map extents (the WMS BBox) in coordinates =
that match both the projection of your map and the extents of your data.

Hi all,
thanks for the input. Right, after setting an environment variable the =
ugly warning disappeared.
But I have still the problem that the WMS layer is not showing up. Any =
hints into this direction? Are the Metadata in the Layer definition =
correct? Do I have to define anything else in the mapfile? [I am working =
with MapScript, v3.5]
Thanks,
Stefan

Marc's response is correct; you will find information about this problem =

Subject: [Mapserver-users] WMS
Hi all,
after spending quite some time on this WMS query subject, I am getting a =
bit frustrated. I read (almost?) all info on this subject. But still I =
don't succeed.=20
In the moment my computer is nerving me with this message:
Warning: MapServer Error in msProcessProjection(): no system list, =
errno: 2 in e:\inetpub\wwwroot\geo_map\map.php on line 275=20
Ok, I know, this is related to the projection list. But: all my other =
services (local and WMS-server) are running quite well. So I don't =
understand why it's coming up with this message. Below the Layer =
definition I use. Any ideas?
