[mapguide-users] WMS and MapGuide Enterprise 2007 problem

[Andy Morsell]

Paul,
Thank you.  That was very helpful.  It didn't even occur to me to go ahead
and save the file and look it...... I agree that if text/xml was sent back
to the browser in the case of errors, this kind of trouble-shooting would be
a lot easier.  

The contents of that XML do reveal a problem:

<ServiceExceptionReport version="1.1.1">
 <ServiceException code="InvalidSRS">
  The spatial reference system specified is not supported. (Found
SRS=EPSG:4326)
 </ServiceException>
</ServiceExceptionReport>

I read through some of the information in the readme about enabling MapGuide
WMS to use unsupported SRS codes, but that doesn't seem to apply here.  It
looks like there may be a problem with the  EPSG:4326 coordinate system
definition in the OgcWmsService.config.awd file?

Andy,

Save the result and open it up in a notepad.  The text of the return may
indicate where the problem is. The whole "download" issue is a side-effect
of the OGC decision to specify their own MIME-types (why?  
why?! why?!!) for the XML error returns in WMS (instead of just using
text/xml like good puppies).  Your browser sees a MIME-type it doesn't
understand, cannot find a handler for it, and falls back on the only
remaining option, save it to disk.  But it's just a text XML chunk, I bet,
and if your lucky it even describes your error condition in a helpful way.
