The message "Java 7 or later is required" is as expected. The other errors seem to indicate a problem with how your Java installation is configured. These errors might be resolved by moving to a later level of Java.

The 'java" executable (or link) needs to be in a directory on your PATH. For most versions of Linux, /usr/local/bin is on the PATH. It seems this isn't the case for the OpenWRT firmware.

still struggeling with above failure, even after nice guys @openwrt forums were helping me with getting jamvm 2.0 running on my nas. would love first to try with older minimserver version which didn't require java 7+. could you help me plz with older download link for v0.8 linux embedded system? later on i need to research on AWT toolkit... :/
if you are interested, belonging thread can be found here: https://forum.openwrt.org/viewtopic.php?id=54849 i think it would be awesome to get running minimserver on openwrt, as it seems quite powerful with luci as frontend, which has nice support for minidlna - by far not as powerful as minimserver when it comes to serving audio!

All MinimServer versions have required Java 6 or higher, so going back to an older version wouldn't help. Also, I can't provide any support for older versions.

On the other thread, I noticed this:

gnu classpath does not support full Java 7

I think this means you are unlikely to succeed with jamvm + classpath. Have you tried using Oracle Java SE Embedded? What CPU does your router have?

[alexinc]

i tried java embedded successfully with FFP on original medion (zyxel) firmware, so cpu support shouldn't be the problem! Dual Core ARM PLX-NAS7820 750 MHz (http://www.mikrocontroller.net/articles/P89626) thats why i'm hunting for minimserver support on openwrt now! when extracting now on openwrt like i did on medion firmware and recommended by uli (http://nas-tweaks.net/419/installation-o...-fun_plug/) i'm failing...
i guess next step is somehow compiling jamvm + openjdk classpath, as this is said to support java 7+ !?

It sounds like you have tried running Oracle Java SE Embedded on OpenWRT. If this doesn't work, what is the problem?

[alexinc]

ok, i'd like to test with embedded java again and would like to post my steps. maybe my mistake is somewhere in between?

i'm referring on this guide (http://nas-tweaks.net/419/installation-o...-fun_plug/), guess my biggest problem is setting the path for/in openwrt...

1. i'm downloading ejre-7u71-fcs-b14-linux-arm-sflt-headless-26_sep_2014.tar.gz from http://www.oracle.com/technetwork/java/e...index.html
2. mkdir /usr/share/java
3. cp ejre-7u71-fcs-b14-linux-arm-sflt-headless-26_sep_2014.tar.gz /usr/share/java
4. cd /usr/share/java
5. tar xzvf ejre-7u71-fcs-b14-linux-arm-sflt-headless-26_sep_2014.tar.gz
5. ln -s ejre1.7.0_71 jre
6. echo "export PATH=/usr/share/java/jre/bin:\$PATH" >> /etc/profile
7. reboot

root@OpenWrt:/# java -version
/bin/ash: java: not found

could adding the PATH to its right position solve all my troubles?

What happens if you type:

/usr/share/java/jre/bin/java -version

If this works, the problem is with your PATH setting. You can check this by typing:

echo $PATH

[alexinc]

nope, no success...

root@OpenWrt:/# /usr/share/java/jre/bin/java -version
/bin/ash: /usr/share/java/jre/bin/java: not found

PATH seems to be setup the right way.

root@OpenWrt:/# echo $PATH
/usr/share/java/jre/bin:/usr/bin:/usr/sbin:/bin:/sbin

It sems you either haven't installed the java executable in the expected location or you don't have the correct version of java. What output do you get from the following commands?

ls -l /usr/share/java/jre/bin/java
ls -l /usr/share/java/jre
ls -l /usr/share/java
