I had a working Java3d project.  Recently I came across the internet article that said that Java3d 1.6.0 was not available.  I downloaded that, removed the existing CLASSPATH, created new CLASSPATH with the new jar files, and also removed the path to the native libraries (the ones that came with 1.5.2).  However, when I run the application, I get this ClassNotFoundException.  As below.

run:
3D [dev] 1.6.0-pre1-daily-experimental daily

I don't know what I am doing wrong.  Please could someone help.  Thanks a lot in advance.
