Installation of Java on the NAS under fun_plug

Today i’ve installed java on my NAS Device (a D-Link DNS-345) what i personally see as a highlight as i can now use software that was not available to me before. Oracle provides a “Java SE Embedded”, which is suitable for NAS devices thanks to its reduced memory footprint. For the following tutorial you need to have fun_plug installed!

Download

Go to the Oracle Page and choose “ARMv5 Linux – Headless”. Now you will be redirected to a survey, where you have to enter Name, Prename, Mail, Organization and Role. Then you will receive the download-Link via E-Mail. Click on this Link and accept the license agreement.

Copy the downloaded file (in my case its name was ejre-7u6-fcs-b24-linux-arm-sflt-headless-10_aug_2012.tar.gz, but that is subject to change) to the NAS. I’ve copied it to /mnt/HD/HD_a2/, please adapt the following commands if you copy it elsewhere.

Installation

First create a directory:

mkdir -p /ffp/opt/java

Then unpack the archive from before:

cd /ffp/opt/java
tar xvzf /mnt/HD/HD_a2/ejre-7u6-fcs-b24-linux-arm-sflt-headless-10_aug_2012.tar.gz

Now create a link to the unpacked directory (“ejre1.7.0_06”):

ln -s ejre1.7.0_06 jre

Now put it permanently into the environment variables:

echo "export PATH=/ffp/opt/java/jre/bin:\$PATH" >> /ffp/etc/profile.d/java.sh
chmod a+x /ffp/etc/profile.d/java.sh

Logout and Login into the NAS.

Installation-test

Check if it works:

java -version

This should display something like this:

java version "1.7.0_06"
Java(TM) SE Embedded Runtime Environment (build 1.7.0_06-b24, headless)
Java HotSpot(TM) Embedded Client VM (build 23.2-b09, mixed mode)

I’ve tried running logstash (http://www.logstash.net/) but CPU seems hogged at 99% 🙁
Tried both 1.6 and 1.7
What experience you have with running other kind of software?

  Other software runs fine 🙂 Maybe you should test with other software?

Bei mir klappt die Installation bis zum Punkt java -version.
Da erhalte ich stets die Fehlermeldung: no such file or directory

Bitte um Hilfe.

    Same here. I tried to install java on my DNS-325…
    login as: root
    root@192.168.2.186‘s password:
    root@DNS-325:~# java -version
    -sh: java: command not found

Using username “root”.
root@192.168.123.92‘s password:
Last login: Mon Sep 3 13:02:29 2012 from 192.168.123.100
root@DNS-323:~# java -version
-sh: /ffp/opt/java/jre/bin/java: No such file or directory
root@DNS-323:~#

Das habe ich nach einem neuerlichen Login eingegeben. Wenn ich mit cd in das Java-Verzeichnis gehe und Java direkt starte, kommt interessanterweise auch dieselbe Fehlermeldung.

Übrigens – folgende Datei habe ich runtergeladen und installiert:
ejre-7u6-fcs-b24-linux-arm-sflt-headless-10_aug_2012.tar.gz

  use tar xvzf NOT xfvz. The last character must be f because hereafter you specify the archive filename

Where should I copy the java tar.gz file in my nsa?
How do I know what to type for the directory (instead of ‘/mnt/HD/HD_a2/’) of the tar.gz file?

(I use NSA 310)

I had a pro blem with FFP 0.7. I need to used this link commnand:
ln -s /ffp/opt/java/ejre1.7.0_10 /ffp/opt/java/jre

For those people of you, who just copied (like i did 🙂 ) :
When creating the link you have to use the correct version number…since this manual uses “ln -s ejre1.7.0_06 jre” and you might have downloaded a newer version (like i did and i did not adhere that at first), you have to use “ln -s ejre1.7.0_21 jre”, or whatever version you downloaded. That worked for me!

Cheers

Hi,

I have down loaded and unzipped the latest version of Java (jre1.7.0_21) on my DNS323 as per the instructions. I created a link to the ejre1.7.0_21 directory. ftp using ssh with filezilla shows the directories are there along with the “jre” link pointing to the ejre1.7.0_21 folder.

However:

root@DNS-STEPHEN:~# java
-sh: java: command not found

root@DNS-STEPHEN:~# java -version
-sh: java: command not found

Any ideas what’s wrong ?.

Thanks

    Hello Uli,
    
    Yes I logged out and loginm agian. I also tried restarting the NAS – same result.
    
    This morning I deleted the folder ejre1.7.0_21 using rm -r.
    
    I then repeated the installation procedure. All the files were unzipped without errors, and all the commands executed without errors.
    
    To check the symbolic “jre” link is working I ran the dir commands;
    
    root@DNS-STEPHEN:/ffp/opt/java/jre# dir
    COPYRIGHT README THIRDPARTYLICENSEREADME.txt bin lib release
    
    root@DNS-STEPHEN:/ffp/opt/java/ejre1.7.0_21# dir
    COPYRIGHT README THIRDPARTYLICENSEREADME.txt bin lib release
    
    However;
    root@DNS-STEPHEN:~# java -version
    -sh: /ffp/opt/java/jre/bin/java: No such file or directory
    
    It seems “java” is not recognised.
    
    java.sh in the /ffp/opt/java/jre/bin/ directory has 755 permissions
    
    Any ideas what might be wrong ?, how do I check if the $path was correctly updated with in the environment variables ?.
    
    Thanks

      Hi stepheng,
      
      i think there is something else wrong.
      
      java is calling something which is not there, because it finds the correct java, but this is not executed.
      
      Can you post a
      
      ls -al /ffp/opt/java/jre/bin/
      
      Thanks 🙂

        I presume you mean just copy the command as you typed (i.e. no sh before or start afterwards ?).
        
        root@DNS-STEPHEN:/ffp/opt/twonky# /ffp/opt/java/jre/bin/java
        -sh: /ffp/opt/java/jre/bin/java: No such file or directory
        
        It seems there is a permissions problem ?.

hello!

I’ve successfuly installed java on my DNS-320 with fun_plug 0.7. looks like it runs without problems.

I’m trying to set autostart for BubbleUPnPServer [installed in /ffp/opt/bubble] with /ffp/etc/fun_plug.local but I’m failing 🙁

when I try in the command line [after PuTTY’ing to my NAS]:
cd /ffp/opt/bubble exec "java" -Djava.net.preferIPv4Stack=true -Dfile.encoding="UTF-8" -jar BubbleUPnPServer.jar $*
everything works fine, server starts and all is good. so I’ve prepared /ffp/etc/fun_plug.local with this code:

#!/bin/sh
cd /ffp/opt/bubble exec "java" -Djava.net.preferIPv4Stack=true -Dfile.encoding="UTF-8" -jar BubbleUPnPServer.jar $*
and I chmod +x to it. when I’m trying to execute it by sending a command:
user@server:/ffp/etc# fun_plug.local
i get “-sh: fun_plug.local: command not found”.

I know that fun_plug.local is executed with bootup, but I want to test it first, to be sure, that I won’t destroy anything 😉
what I’m doing wrong? [disclaimer: I’m not as good with linux, so it’s something like walking in the dark for me ;(]

regards,
piotr

Hi Uli,

I installed this version:

on a DNS-323.

java -version

I’m installing Java in hopes to run a multiplayer Minecraft server on the NAS for my kids. Any help is appreciated.

everyone is having problems because the instruction are wrong:

when you need to make the Permanent path this is the exact commands you should type with the proper paths
echo "export PATH=/ffp/opt/java/jre/linux_arm_sflt/jre/bin:\$PATH" >> /ffp/etc/profile.d/java.sh chmod a+x /ffp/etc/profile.d/java.sh
