VisAD compilation problem on NT

Hi there,

I'm trying to install VisAD on a high-end NT machine and have
come across a problem.

I've unpacked the VisAD jar file into \visad, then from this directory
I ran nmake (as per the FAQ).

The machine starts compiling, but then I get errors like:

error: Class visad.RemoteServerImpl not found
error: Class visad.RemoteFieldImpl not found
error: Class visad.RemoteFunctionImpl not found
...

10 errors
NMAKE: fatal error U1077: 'C:\WINNT\system32\cmd.exe':
        return code '0x1'
Stop.

Note: I am using jdk1.2beta4 for the compilation.

Any suggestions/ideas ?

Thanks in advance,
Justin.
