Heh. As I matter of fact I did. However it definately pays to 
be a little less hasty and more methodical. Below is what 
happened when I tried to build a transcript of my problems with 
the compiled version for the author, Ugo Taddei:

Hi Ugo,

I cc'd you a message ealier which detailed how I manage to get
DV to work from source code. This one is about the error messages
with the compiled version. The errors were along the lines of
"Exception in thread ... No classdef found ... DEMViewer".

-host system is Win2ksp1
-Java2 SDK 1.3.1 and Java3d SDK are installed

In a CMD shell:

Ooops!
Usage: dgm3d elevation_raster  attribute_raster_1 attribute_raster_
        where "raster_1 or 2" are valid ArcGrid files
        or Raster 1 or 2 is optionally a Jpeg or Gif file

...Q#$%@#%!!... it works now. I think must have been entering an
incomplete/wrong classpath before. L:}

Well, I'll leave the sequence here for posterity. Thanks again
for your time,
