[mapguide-users] RE: WMS Data Source?

[Jason Birch]

OK, weird choice from the specification pov then.  Counting on the persistence of a single external resource in a distributed system doesn't seem like a great idea.  One change brings the whole thing tumbling down.
 
What do you mean by ourselves?  Included in the MapGuide installation (local reference)?  Hosted somewhere at OSGeo?

Hi Jason,

 

Just a bit of historical perspective:

 

> ... instead of digitalearth (weird choice):

 

Deprecated, perhaps, but not necessarily weird. It's what the relevant specs call for, and until recently they seemed to work just fine.

 

Fortunately, it looks like we've decided to host the DTD files ourselves to eliminate that external dependency.

This is a known issue:

 

https://mapguide.osgeo.org/servlets/Scarab?id=MG434 <https://mapguide.osgeo.org/servlets/Scarab?id=MG434> 

 

It looks like you may be able to fix it by grabbing the three fixed files from SVN:

 

https://mapguide.osgeo.org/source/browse/mapguide/branches/1.0.x/MgDev/Server/src/Wms/ <https://mapguide.osgeo.org/source/browse/mapguide/branches/1.0.x/MgDev/Server/src/Wms/> 

 

or just updating the AWD templates on your site to hit OGC instead of digitalearth (weird choice):

http://schemas.opengis.net/wms/1.0.0/capabilities_1_0_0.dtd <http://schemas.opengis.net/wms/1.0.0/capabilities_1_0_0.dtd> 
http://schemas.opengis.net/wms/1.1.0/capabilities_1_1_0.dtd <http://schemas.opengis.net/wms/1.1.0/capabilities_1_1_0.dtd> 
 
<http://schemas.opengis.net/wms/1.1.1/capabilities_1_1_1.dtd> http://schemas.opengis.net/wms/1.1.1/capabilities_1_1_1.dtd
 
respectively, for the three templates.
 
I recall something similar with LiteView in MapGuide 6.x, and I think I had to repoint to a local DTD.  Bit fuzzy on that though; I gave up on LiteView pretty quickly.

Jason

There is an OSGeo FDO WMS data provider for this purpose
(https://mapguide.osgeo.org/servlets/ProjectDocumentList?folderID=100&expand
Folder=100&folderID=0).  However, I just tried working with it and there
appears to be a problem today.  If you try to use it to define a data
connection, and then enter a WMS server name and press the Test Connection
button, you will get an error

"An exception occurred in FDO component.
XML Document parse error at line 8 column 3: An exception occurred!
Type:NetAccessorException, Message:The host/address 'www.digitalearth.gov'
could not be resolved "

It appears that the FDO provider is looking up a DTD at digitalearth.gov and
their web site is currently down (at least on my end).
