Re: [mdr-users] XMI reading fine, but empty result collection

Hi,

The solution was quite stupid: I downloaded other MDR jars, and things appear to be fixed.
I did some tests, and it turns out to be jmiutils.jar. The bad one was dated 2004-08-26. The odd thing is that this very jar is used e.g. by AndroMDA, and there don't seem to be any MDR problems there...

Any idea as to what might have been wrong in this jar?

Thanks,

Hans
