DOCBOOK-APPS: Fop?

Hi,
Having now taken a file from
XML --> HTML via xsltproc
from
XML --> .fo via xsltproc
from
.fo --> .fop via xsltproc

and downloaded the fop.sh I try to run
fop.sh from the command line (CYGWIN),
and am told:

[: Doc:  unknown operand
[: Doc:  unknown operand
java not found

Reading the script I can't rightly figure out
where it wants java to be.  I have java 1.3.1
on the system, even created a directory java/bin
for it in the same directory I am running fop.sh from.
Help!!!!  I am soooooo close??

Thanks.
