can't find java on synology 213j

[charlesw]

Hello,
I've just installed a Synology 213j NAS and have followed the instructions for installing Minimserver.
1/ I installed the Java SE for embedded package (using ejre-7u40-fcs-b43-linux-arm-vfp-hflt-client_headless-27_aug_2013.tar.gz). It installed and says it's running.
2/ I installed MinimServer 0.72 (using MinimServer-0.72.1-arm.spk) and it installed.

However MinimServer can't start and the log says :
" sh: /volume1/@appstore/java7/jre/bin/java: not found "

I've looked but haven't found a solution (I admit to not being a NAS expert, although I did play around with Linux for a while when it first came out).

MinimServer worked fine when I installed it on my Mac (OSX 10.8).

In case it helps, I notice that there are "home" and "homes" sharepoints on the NAS, and the MinimServer folder is in "homes".

Can you please help ?
Regards, charlesw
