RE: [Newbie] Help with ReadingModelSample.java NSUML1_4

Martin, Sorry for the confusion, I haven't really had a chance to look at the architecture of MDR and made some wrong assumption about how this sample works.  I guess the model would be expressed in novosoft mdf objects (not familiar with this framework yet) not MDR objects.  Bottom line, I was hoping to use the sample code as a means to read in an XMI file and examine the resulting model through the instanciated model class objects (be them MDF, MDR, or JMI, etc. objects).  I would have expected there to be >0 root objects when reading in the example XMI file supplied with the sample program.  Thanks, Doug.

Hi,
I am not sure what you are asking for. Are you looking for a code that 
does the same thing on top of MDR?

The ReadingModelSample.java example looks like a great place to start, but it doesn't generate the results I would expect.  Shouldn't there be a number of root objects?
