jigsaw release 2.0.2 - classpath problems

I'm running on W98.
In C:\autoexec.bat I've added

SET CLASSPATH=.;C:\jsdk2.0\lib\jsdk.jar;C:\jsdk2.0\bin\;
C:\jigsaw_2_0_2\Jigsaw\classes\jigsaw.zip;SET PATH=%PATH%;

If I execute 

java Install 

in MS-DOS, C:\jigsaw_2_0_2\Jigsaw\Jigsaw
I get a 'bad command'
What's wrong?
