Kenneth,
There is no
error in the error.log with
the example using the Nasa WMS. Unfortunately, the WMS isn’t always
displayed.
Have you an idea of the problem?
I tried an
other WMS (http://www2.demis.nl/mapserver/Request.asp?)
and the error.log gives the following information:
<2009-03-17T10:27:14>
Ajax Viewer 127.0.0.1 Administrator
Error:
Failed to stylize layer: wms
An exception occurred in FDO component.
The spatial context 'EPSG:4326' is not supported by the layer
'Countries'.
StackTrace:

Failed

An
exception occurred in FDO component.
The
spatial context 'EPSG:4326' is not supported by the layer 'Countries'.
I don’t
understand the error because
the GetCapabilities of
the Demis
WMS indicates that the layer “Countries” supports the EPSG:4326 ?
….

Feel
free to log this as
a defect for Maestro.
I'm guessing that it is a problem with coordinate systems not matching
up.
You can look in the error.log for MapGuide to see if this is what
happens.

Hi
Kenneth
Thanks for
these precisions.
I have
always a problem to view the WMS in
the MapGuide viewer.
With
Maestro, the “preview
item” of the layer (it is the same for the map and the layout)
doesn’t show the WMS. But if I use MGOS Web Studio to analyze the
layer,
the preview tool displays the WMS (it doesn’t work with the map and the
layout).
Thanks,

After
you select the
FeatureSource, you should see two comboboxes below the selected
ResourceID.
These are left blank, due to the bug you mentioned.
Simply click the combobox and select the only entry avalible.
Repeat for the combobox below.
You can now save the layer.
To publish a layer as a WMS entry, right click the FeatureSource and
select
properties.
Then fill out the "WMS" tab, and remember to check the
"Publish" checkbox.
Then click OK, and the layer should appear as a WMS layer when issuing
a
GetCapabilities request.

Hi Kenneth,
Could you
explain me in more details the
procedure aiming to select manually the schema and column?
In addition
(for WMS server), is it
possible to publish a layer (SDF or SHP feature resource) like a WMS
with
Maestro?
Thanks,
Arnaud De

Hi Arnaud.
That is a bug in Maestro.
I have committed a fix for it, so it will be in the next release.
If you manually select the Schema and Column, you should be able to
save,
and perhaps use the layer.
The cryptic message means that you have forgotten to fill out those two
fields
:).

Hi,
I created a MapGuide WMS
feature source according to
the “FdoWmsNotes” (http://trac.osgeo.org/fdo/wiki/FdoWmsNotes).
My first WMS feature corresponded to the example given in this note
(NASA WMS).
I created with success
the feature resource (see
picture).
After all steps
described in the note, I used
MapGuide Maestro (1.0.9) to create layer definition.
But when I selected the
feature resource in a new
layer, I received the following message :
‘Failed
to
read schema from data source. The operation gave the error message :
Value
cannot be null. Parameter name: input.’
And when I saved the
layer, I encountered the
following exception:
“System.Exception:
The remote server returned an error: (559) MgDbXmlException.:
An

occurred in DB XML component.
Error:

I tried also with others

always the same errors.
