Re: [Newbie] Help with ReadingModelSample.java NSUML1_4

Yes, unless the file is empty, there should be at least one root object 
- typically an instance of MofPackage.

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.

>>Downloaded and built nsuml1_4 code and samples.  I'm interested in scoping what is requires to read in a  MOF 1.3 compient XMI 1.x file into MDR objects using the framework.  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?
