[bpel-dev] EMF resource loading puzzle.

[Michal Chmielewski <michal.chmielewski@xxxxxxxxxx>]

Can someone point out to me what the reason for this exception might be ?

If I attempt to load this WSDL from this location: 
http://ws.strikeiron.com/InnerGears/ForecastByZip2?WSDL

I get this exception in the Eclipse console (the parent eclips co

org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1$DiagnosticWrappedException:

However, when I save the source of the WSDL to a file and load that 
file, it loads OK, no exceptions at all.

To add insult to injury, this URL loads fine: 
http://localhost/wsdl/cache/CATrafficService.wsdl

So it seems like a difference between http:// and file:// loading, but 
not so since one WSDL works as a file but not as a http. The only 
difference between the
working and non-working http accessible WSDL is the query string, ?WSDL 
on the one that does not work.

If you have the most recent source from the tip, try attaching these 
WSDLs to the imports, either in the import properties or by trying to 
add a partner link.

It's probably something obvious about EMF that I don't know about.  Ideas ?
