installing minimserver on netgear R7000 router flashed with advanced tomato firmware

[dafart]

for both ejdk1.8.0_121/linux_arm_sflt/jre/ and jdk1.8.0_121/jre/ (from jdk-8u121-linux-arm32-vfp-hflt.tar.gz) I get the same error:

-sh: java: not found

nothing more.

echo $PATH
/opt/java/jre/bin:/opt/bin:/opt/sbin:/bin:/usr/bin:/sbin:/usr/sbin:/home/root:/mmc/sbin:/mmc/bin:/mmc/usr/sbin:/mmc/usr/bin:/opt/sbin:/opt/bin:/opt/usr/sbin:/opt/usr/bin:
