Java SE Embedded package for Synology NAS

There is a lot of good Java software, but it’s difficult to get Java running on a NAS. I decided to do something about that, mainly to pave the way for a Serviio package that didn’t require a huge guide to install. In compliance with the Oracle EULA the Java binaries cannot be redistributed, so this package looks for the downloaded .tar.gz archive in the public shared folder on the NAS. The end user is required to register with Oracle to get the file, as you can see from the description below. I also added locale support to the underlying Linux since Java requires this for UTF-8 support when reading from the filesystem (DSM 4.3 later included this). Timezone support is also configured.

This package installs Java SE Embedded which is purposefully designed to run on low specification headless hardware. It should be noted that Synology Java Manager (only available on Intel products) is the full Java Runtime Environment, and consequently uses more RAM. By default you should use Java 8, unless the application you want to run specifically requires Java 7.

Please note that Oracle ceased maintaining Java 6 in 2012, so it should be considered a serious security vulnerability. The Java 6 package has been withdrawn from the package repository for this reason. If you need it to run a particular piece of software you may download it here for manual installation. Please also note that Oracle retired support for PowerPC CPUs following Java 8 Update 6, so the PowerPC package remains at that version.

Java Package



  • In Synology DSM’s Package Center, click Settings and add my package repository:
    Add Package Repository
  • The repository will push its certificate automatically to the NAS, which is used to validate package integrity. Set the Trust Level to Synology Inc. and trusted publishers:
    Trust Level
  • Now browse the Community section in Package Center to install a Java SE Embedded package:
    The repository only displays packages which are compatible with your specific model of NAS. If you don’t see Java Embedded in the list, then either your NAS model or your DSM version are not supported at this time.
  • If you have a multi-bay NAS, use the Shared Folder control panel to create a shared folder called public (it must be all lower case). On single bay models this is created by default. Assign it with Read/Write privileges for everyone.
  • Register with Oracle and download the appropriate version of Java SE Embedded for your CPU architecture and save in the public shared folder on your NAS. Note that to get any version of Java older than the current one you will need to follow the Oracle Java SE Embedded Downloads Archive link on that page. If in doubt, attempt to install the package first, and the error message will tell you which specific download version is required.
  • If you have trouble getting the Java archive recognised, try downloading it with a different web browser. Some browsers try to help by uncompressing the file, or renaming it without warning. I have tried to code around most of these behaviours. Use Firefox if all else fails.

    1. Tony Mason

      Can you help – I have been successfully using the Java SE 8 on sysnology but have just tried to upgrade to the latest version by uninstalling the previous. I downloaded the latest and uploaded successfully to the NAS. The problem is when i hit ‘Run’ it says ‘starting’ but then stops.

      The log says

      /var/packages/java8/scripts/ line 74: java: command not found

      the file i uploaded is 1.8.0_101-0041

      Any help would be great.



      1. DQ

        on my DS415+ the was failing due to ‘uname -m’ returning “x86_64” which wasn’t accounted for. I manually installed everything to get it working, we’d need a package update to fix it properly.

    2. yeastie99

      Installing Java SE Embedded 8 via PCLOADLETTER on my Sonos Play 5 does not work, because it recommends Version Update 161, which is the only version not available on the oracle website (page not found after clicking on their own link). The newer Version Update 171 is not supported from your package. By just renaming 171 to 161 in the public folder, the installation works but I can’t start it afterwards because the command to start “was not found”. Can you update your package or help, because oracle won’t. It’s oracle. :)

  1. M.S.

    Hi, every time I am trying to install the “Java SE Embedded 8” package, I’m getting the error “Failed to download “java8″.”

    Does anybody know a Solution?

      1. Ian

        I’m trying to install Bliss with Java 8, but all your link takes me to is the latest: ejdk-8u111, and yet the error message in the program is asking for 8u101. Please could you offer me a link to the correct solution here. Many thanks Ian

  2. Sebastian

    Hello, I am new to java. I have installed java8 to my DS211j according to above instructions as I want to create some programs using java.

    After installing the package I can’t see “java” command in bash. I tried to look for its location and I found java program on /volume1/@appstore/java8/ejdk1.8.0_101/linux_arm_sflt/jre/bin

    So do I just add this path to $PATH variable and it should work? Or should I run scripts mentioned above (, etc.) in specyfic order? It seems that those scripts just do not work.

    Second thing – does this package also contains jdk? I can’t javac program anywhere,

    Maybe those questions are basic ones, but I am new to it, so please help :)

  3. Fry

    hey ! is it possible to start and stop the execution without a lot of commands ?
    because it takes a lot of ressources !
    any suggestion would be great :)


  4. manew12

    hey ! do you have planned an update for “ejdk-8u111-linux-i586.tar.gz” ?
    because we can’t install java now.
    thk’s a lot for your work

  5. Jack

    Hello. Great work on this. Oracle has since updated their java to version 8u111. I can’t find a link to download the 8u101. Can you please update your package to reflect the latest java version?
    Thank you

  6. SophieS

    Is there any way to set a universal system property that directs any NAS package that needs Java to use this patters Java installation ?

    While installing community packages that require Java, Package Center will often not let the install proceed without first installing some version or other of Java – so you may end up with 3-4 prerequisite Java packages installed that are more or less the same (using the same files from Oracle) but by different community publishers …

    1. Souga

      But you only get the old version if you’re registered at Oracle. I want to install Java 8 but can’t because they moved to 111 but the Installer demands 101. Is there a ways to update?

  7. Gero


    i am trying to install the 101 version. When I try to install the package it gives me the issue, that it cannot find the “gz” package. Oracle names it differently after the download. The name then ist: ejdk-8u101-fcs-b13-linux-arm-sflt-21_jun_2016.tar <— HEEEELP Plz

    1. Gero

      Ok fixed that, but the package does not start. I renamed the file. Is that the Problem, because the installation was successful or is my DS to old. Got an 211j.

  8. patters Post author

    The Java package has been updated to Java 8 update 111, and it will now work on ARMv7 systems that broke after DSM 6.0 changed the whole Linux distro’s ABI.

    Hello. Oracle has since updated their java to version 8u121. I can’t find a link to download the 8u111. Can you please update your package to reflect the latest java version?
    Thank you

    Hey patters. I’m unable to install Java 8 at the moment. I get a message:

    “Java binary bundle not found. I was expecting the file /volume1/public/.tar.gz”

    I have both the GZ files:

    me@ds216j:/volume1/public$ ls
    ejdk-8u111-linux-arm-sflt.tar.gz ejdk-8u111-linux-armv6-vfp-hflt.tar.gz

    Looks like the JAVA_BINARY variable isn’t being correctly resolved but I can’t work out why. I have downloaded to test it, but it looks like just running it doesn’t give certain variables, e.g. how is SYNOPKG_PKGNAME set?

      Hi Dan – I’ve updated the package for the newer JRE 8u121. Lots of the variables only exist in the shell the package manager invokes which is why developing for Synology is such a pain. When a script derails it’s hard to debug, other than by building a new copy of the package and testing, but having it echo output to a log.

        Synolog DS216j: Java binary bundle not found. I was expecting the file /volume1/public/.tar.gz

        ejdk-8u121-linux-armv6-vfp-hflt.tar.gz is in public folder. :(

    Hi, I have a Synology DS216j. The last version that worked was Version 8 Update 101. I cant install any version afterwards anymore. I have put ejdk-8u121-linux-armv6-vfp-hflt.tar.gz in the public folder, but during install i get the message: Java binary Bundle not found. I was expecting the file /volume1/public/.tar.gz

    What can i do?

    1. patters Post author

      The only reason I can see for this happening is that Synology is not exposing the expected value for the package manager variable “${SYNOPKG_DSM_ARCH}”. For your system that value should be “armada38x”, as seen here. Can you try downloading and manually installing this modified version of the package which will output a more descriptive error text:

      It should now say “Java binary bundle for ${SYNOPKG_DSM_ARCH} not found…”
      Please let me know what it reports for the value of ${SYNOPKG_DSM_ARCH} when it fails to install.

    Sorry, i thought that my last post wasn’t saved, so I created another one. Alex = apollo821

    I installed the package manually and this it what it says:
    Java binary bundle for armada38x not found.

    So it seems to be correctly set.

      I see the problem. It was a stupid typo. I’d written armv7l-hlft instead of armv7l-hflt which is actually quite hard to see even when you’re looking for typos. Fix imminent.

    I have a Java error trying to run OpenHAB2 on my DS414 exactly like:
    DSM 6 is installed.
    /proc/cpuinfo reports:
    Processor : Marvell PJ4Bv7 Processor rev 2 (v7l)
    Hardware : Marvell Armada XP Development Board
    Based on the change log I expected to install the hard float version, but the package insisted on installing the soft float. Is the package correct that I should have the soft float Java?

    1. dfrap

      One option I tested is to rename the Oracle package. So when I renamed ejdk-8u121-linux-armv6-vfp-hflt.tar.gz to ejdk-8u121-linux-arm-sflt.tar.gz, Java loaded and OpenHAB seems OK.

  15. Michael

    I tried to install java8 on my DS411 (ARM) The installations seems to be successfull, but the java does not start.
    I too a look into the problem and as far as I can tell the start_stop_status script writes
    “PATH=$PATH:/var/packages/java8/target/ejdk1.8.0 121/linux arm sflt/jre/bin”
    int /root/.profile which likely supposed to be
    Any ideas?

    I just thought I’d add my latest story to the mix… After persevering with Crashplan on Synology/Xpenology for about 5 years now, I’ve finally given up. I moved to Synology Hyper Backup To Amazon Cloud. Same yearly price for unlimited backups ($59 or so) and so far, it has saturated my upstream continuously at 20Mbit doing the initial backup. Thats something that Crashplan only very rarely managed.

    Thanks for all your hard work in getting this working over the years.

    Dear Patters…
    I have a small issue with the package… Few months ago, I have installed the Java package with ejdk 8u101… and I have also used your package for open remote… I am working with a synology DS 214 cpu MARVELL Armada XP MV78230 and DSM 6. Everything was fine… then I have encoutered some bugs with open remote and I have decided to reinstalled the java package and open remote… the problem is now that the package is provided for ejdk 8u121… the installation of both packages work fine and they seem to run perfectly… but I can not see the open remote controller (page blank or even read the log of the package)… I suspect some compatibility issues with the java package… what do you think ?
    Thanks in advance

      Hello. Oracle has since updated their java to version 8u131. I can’t find a link to download the 8u121. Can you please update your package to reflect the latest java version?
      Thank you

  18. Ethan

    There is no x86 download for the 121 version. All I see is ejdk-8u121-linux-i586.tar.gz
    Can you update, as the i586 gives me an error when I try to install Crashplan

  19. JoBBe


    Can you update to ejdk-8u131-linux-armv6-vfp-hflt.tar.gz, the 8u121 version isn’t downloadable anymore.

  20. Anders

    Got a 212+, looking at ejdk-8u131-linux-arm-sflt.tar.gz
    got it through the script by just renaming the file back to 121. Kind of supriced there…
    but then I ran in to this JAVA_HOME not being defined.
    don’t get any real suggestions here so i suspect my shortcut got back to me.

      I might just have accidentily found it in the etc/profile – links was all wrong there. at least now it does not fail at the same spot….

  21. Mike

    Hi – Looks like Java version at Tinyurl address is now 131 (specifically ejdk-8u131-fcs-b11-linux-i586-15_mar_2017.tar), so standard install no longer works… Is it possible to update please?


  22. Marchel

    I have installed Java 8 on DS213+, latest seems to be .6 but need at least .101 for OpenHAB2 cloud.
    Is it possible to install a more recent version on DS213+?

  23. Martin

    When will your great script support current Oracle Java SE Embedded Version 8 Update 131 version?

  24. eric

    Trying to install Serviio to my NAS but can’t get beyond the Java stage. Message pops up during install about “not finding expected file” 121 in “public” folder (which I have created). The Oracle webpage sited only serves up version 131 so I’m assuming that is the issue.

  25. Felix

    The latest Java Version was released at April 18th, but the App is still running the old version. Will there be an update soon?

  26. Aurelio

    Since April 18, Java Embedded is available in version 8u131. Can I use the same installer and just use the new java archive, or do I have to wait for a new Synology package?

  27. paulm

    Hi the version is now update 131 is that why I cannot install using the script provided? Is there a work around I can use. I looked at the scripts but they’re too complicated for me!

    Thanks for help.


    1. mpaulm

      I also tried renaming the 131package file to 121. The install proceeded ok, but then Serviio failed with a Java_Home is not defined message

  28. Scott Potter

    I can install java 8 to run on my DS415+ (with either JCE policy), but it will not run. java 7 installs and runs fine. suggestions?

  29. Mikael

    Hi, Have installed this version on my DS111 successfully 1.8.0_144 but have this in the logs:
    /var/packages/java8/scripts/ line 74: java: command not found


    and when I try to install Minecraft server, I get ‘Java home is not defined’ error
    How I can fix the problem?
    thank you!

  30. San

    It looks like Java SE 8 has been updated to build 151, does the install script need an update? or is there a workaround for this install?

    Thank you!

  31. noodles

    Installed version 1.8.0_151 on my DS1515+ but have this error in the logs when trying to start the process:
    /var/packages/java8/scripts/ line 74: java: command not found

      I have updated the package with experimental aarch64 support for this architecture. Please can you try it and report whether it works? It will prompt you to download the full (not Embedded) JDK 8 which is the only one that seems to have an aarch64 compile.

  32. corduroy

    Hi – Looks like Java version at Tinyurl address is now 161, so standard install which looks for 151 version no longer works… Is it possible to update please?


  33. Dennis Denneboom

    Is this still working?
    I can find Java 7 and 8 SE Embedded, but I can’t find the Majong Mincraft.

  34. Stefan

    I just removed an older version of Java from my NAS (Synology DS211+) because I wanted to update java. Now this file: ejdk-8u161-linux-arm-sflt.tar.gz is missing and it isn´t available on the oracle hompage anymore. I searched now for two days without any result. Can someone please help me out. Maybe someone has this file on harddrive and can send it to me.

      1. Richard

        Hi Stefan & barisakkum

        Did u find the version anywhere ? (ejdk-8u161-linux-arm-sflt.tar.gz) ??

  35. Martijn Damen

    Unfortunately I have the same issue, the archive on Oracle does not work somehow and thus there is no way to download the ejdk-8u161-linux-arm-sflt.tar.gz.

    Lessons learned, be quicker with upgrade :S

  36. Richard

    Hi :-)
    Just wanted to reinstall JAVA (my NAS chrashed) … yur script is only for JAVA 8u161 … But the Downloadlink @ ORACLE is broken for this Version … any possibility to upgrade your script for JAVA 8u171 ?? ragrds, RIchard
    Need the file: ejdk-8u161-linux-arm-sflt.tar.gz

    1. dfrap

      One option I tested is to rename the Oracle package. So download the current version for your hardware from oracle and rename it to the name the script requires.
