How to visually see an XMI file? UML Mapping

[JREAM]

Hey..

I used pears UML thing to convert a directory of classes to a UML File so I could visually see a map of my objects.

I can look at the XMI file as a XML file in a browser or text, but I don't understand how I visually see how this is mapped out.

I searched all over Google for a UML Viewer, or a XMI to UML, etc.

Is this a waste of time?
