Hard time with UML2MOF tool

Hi All,
I am trying to convert my very UML model into a MOF model.  I took a 
look at the UML2MOF tool.
I am having hardtime getting it to work.

The online tool for UML2MOF seems to be down. 
http://www.soluta.net/xmi2mof.php

The downloaded UML2MOF wont just run.  I had to download the sources and 
try to compile and run it myself.
I tried this in NB 5.5 Enterprise Pack preview.  I am getting the 
following error.

Any help is appreciated.  BTW, the MDR site does not seem to have any 
updates since 2002. The sources wont work in JDK 1.5.  I am new to this 
MDR stuff . Is it being widely used or it has been one of those 
technologies that has not found any early adopters.  Please pardon my 
ignorance, I am new to NB development.
Thanks,
Anand.
