[mdr-users] Cannot create URL

Hi,

I am new to MDR and I think my problem should be easy to solve. Probably 
it has already been posted a couple of times but I didn't find anything yet.

I am trying to read an XMI model generated with MagicDraw. I always get 
an error message like

org.netbeans.lib.jmi.util.DebugException: Cannot create URL: 
andromda-profile.xml

This also applies to all other profiles referenced by my uml model. 
However the profiles are all available in the same folder als my xmi, 
besides they are in the classpath but I still get this message.

The solution is probably quite simple, but I am really stuck.
Thanks in advance,

flo
