Java SE Embedded package for Synology NAS

1,229 Replies

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 The Java 6 package has been withdrawn from the package repository for this reason.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.

Instructions

  • 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:
    Community-packages
    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.

      Hi, I need to install Java on my DS214+ for minimserver, I have no internet connection going into the router that my synology is connected too. Basically my internet log in is to a different SSID and I have to log in on a landing page which allows me online for 2 hours at a time. Normally with Synology you can just download the offline file and do a manual install, looks like the only way with Java is to redirect it to a URL, but obviously this doesn’t work in offline mode. Can anyone help?

        Download the Java 7 spk file here: http://packages.pcloadletter.co.uk/downloads/java1.7.0_71-merged-0029.spk
        Try to install this. It will fail with an error message telling you which specific Java file it needs you to download from Oracle.
        On your other computer, use Firefox and go to http://tinyurl.com/javaembed agree to the licence conditions and download this file (you need to sign up for this).
        Create a new shared folder on your NAS called public if it does not already exist (all lower case).
        Place your downloaded java .tar.gz file in the public folder. Manually install the .spk file again and it will work.

        Oracle link does not work and is not downloadable from the official website and the 7u60 doesn’t work.

        I have the same CPU in my NAS (1.6GHz instead of 2.0GHz in yours). I just removed and reinstalled the package from the repo. It’s working fine so you maybe have some kind of bad download from Oracle. Delete your existing Java file from the public share. Now try to install the package without the .tar.gz file in public. It will fail, but it will tell you precisely which file you need to download from Oracle. Use Firefox to do this, just to be absolutely sure. It’s the only browser that doesn’t try to unpack or rename .tar.gz files. Then report back here please.

  8. derkuechenmeister

    Apparently, there is a new version of the JRE7 available (07_may_2014 instead of 17_mar_2014). Could you update the package please? Furthermore, why are you using the soft-FP version for the DS214+/ArmadaXP instead of hard-FP?

    Thanks for the great work!

    1. patters Post author

      I have updated the Java 7 package to support update 60. In testing with Armada 370 the HardFP ABI version didn’t work IIRC. I use the SoftFP ABI (application binary interface). It’s still using the hardware FPU, but the code is compiled in a way that doesn’t break backward compatibility with CPUs with no FPU. See here for an explanation: https://wiki.debian.org/ArmHardFloatPort#ARM_EABI

      I have published the Java package for this CPU but it’s not yet been confirmed working.

      Jorge – can you get Java installed and does it correctly display the version information in the package Log in Package Center? If so I can add support for this model to the other packages like CrashPlan and Serviio. To do this I will need some additonal info from you.

      Please can you post the result from running cat /proc/cpuinfo while connected to your NAS via SSH? Log in as the user root using the same password you defined for the admin account.

      Please also run uname -a and paste the result here. Thanks!

      You mention in the notes the following:
      The package downloads the CrashPlan installer directly from Code 42 Software, following acceptance of their EULA. I am complying with their wish that no one redistributes it.
      CrashPlan is installed in headless mode – backup engine only. This is configured by a desktop client, but operates independently of it.

      Per my post i cannot finf crashplan on the DS414j at all.

      Thanks Jorge, that’s perfect. I’ve nearly completed a new Serviio package and that will allow me to add some detection in for that processor. I have built an optimized compile of FFmpeg since that processor has a NEON vector unit, so it should perform better than the other ARMv7l systems.

      It does not delete the PATH variable from the profile. It removes the second PATH modify statement that this package makes. If you want to add your own entries to the PATH, then you should instead edit the first PATH= statement, not the one that shows PATH=$PATH:/volume1/@appstore/java7/jre/bin

        When the update is installed DSM deletes the entries made in root / .profile

    Great job on the java package. Is it possible to get the non-embedded 64-bit java to run on DSM because the embedded java appears to be 32-bit only and limits the heap size to 4 GB at most. I currently have 4.5 TB of data to be backed up (with more to come) and Crashplan recommends 1GB heap memory per TB of data. I’m running DSM on an HP N54L micro server with 16GB RAM (upgraded specifically for Crashplan) and 11GB usable storage space. Crashplan is working fine so far with 2GB java heap memory but it’s only backed up 1.5 TB so far.

    I unfortunately lost a drive about a month ago and was semi-successful in getting Crashplan back on the DS712+.

    However, just looked and saw it had stopped.

    Tried to restart and no dice. In my troubleshooting, decided to try to uninstall Crashplan and reinstall. However, I cannot get Crashplan to install.

    The download looks fine, it goes to install but states I do not have Java installed or configured.

    I’ve got your Java SE Embedded 6 / 1.6.0_38-0023. Do I need to go to a different one? Guessing it’s just a simple as uninstall / reinstall Java, but wanted to double-check first.

    Thanks in advance for the assist.

    First, thank you for supporting the community. You’re awesome.

    After updating to “DSM 5.0-4493 Update 2″ on my DS213+, I noticed my Crashplan was not working. All has been well up to this point, and I have about 1TB backed up. So I:

    – Uninstalled Java SE
    – Uninstalled Crashplan

    Now when I attempt to install either Java 7 or Java 8, the installation works but there is no RUN option in the package center, just UNINSTALL. I’m ssh’d in and this is what I see:

      There hasn’t been a Run option for many versions now (to mimic Synology’s Perl package for instance, since Java does not run continuously). Remember that if you were connected via SSH before the package was installed and started, you would need to quit and restart your session to pick up the new environment variables – or run:
      source /etc/profile
      source ~/.profile

      What is the status in Package Centre? Running or Stopped?

      I have a similar scenario. Updated to same DSM 5.0-4493 Update 2, uninstalled Java and uninstalled Crashplan, installed Java 7, installed Crashplan. Java shows “Running” for me, but I cannot get Crashplan to start. It says “Started” and then promptly returns back to “Stopped.”

        I also have a Marvell Kirkwood and I don’t have this issue. Is your NAS bootstrapped? Mine is not so I think that can be the only explanation. Let me know – it’s possible the version of sed that ends up higher in the path after bootstrapping has slightly different syntax.

      4. litris

        Solved! But I can not say exactly what was the failure to I made two changes.

        1. Since I had export “LC_ALL = es_ES.utf8” and I put as export “LC_ALL = en_US.utf8”

        2. The first line you write your java package is “PATH=$PATH:/volume1/@appstore/java7/jre/bin # Synology Java Package” instead of the beginning of the last line was really the last.

        The latter is no fault if your package installation or editing mia doing tests with “config file editor”

        Thanks.

  28. litris

    Everything worked fine.

    I just uninstalled the old version of your package to update the new what the message said “before upgrading uninstall previous version”

    And it works if I put Java in the Java version had me indicates that this well.

For now I installed ejre-7u60-fcs-b19-linux-i586-headless-07_may_2014.tar.gz will it be OK to install V 8 over the top of V7 when you get this fixed or will I need to uninstall and start over ?

        The package will not let you. You need to stop any packages using Java, then uninstall the old version first.

        Again, Thank you as you have probably already guessed, I am a complete novice when it comes to Linux. Is there anything special I need to do to uninstall or just stop my crash plan go to your package uninstall and then install the new version and then restart crash plan?

    Have added the package repository URL to my DS509+, but no packaged for java are available in the package center.

    Hi Patters,
    I just updated my DS411+II to the latest DSM version (5.0-4493 Update 2). I also was notified that I needed to update my Java. I stopped my CrashPlan, uninstalled Java, downloaded/transferred the specified Java 7 headless file and re-installed Java w/no problems. I went to re-install CrashPlan (successful), but when I go to Start, it says “Started” but then promptly goes back to “Stopped” status.
    I noticed that when CrashPlan was uninstalled it removed the Crasplan user, and when reinstalled, it re-creates it (without appropriate permissions to the Shares), so I re-added those permissions. But even still, I do not know how to get the Crashplan to stay “Started”.
    Any ideas? Thanks!

      I would advise using Java 7 for most things, unless the application you are trying to run explicitly supports version 8.

    213j NAS Trying to install Java 8. Have registered, copied ejdk-8u6-fcs-b23-linux-arm-sflt-12_jun_2014.tar.gz to /volume1/public, and added http://packages/pcloadletter.co.uk to the package installer. I can SSH as admin and lt shows the package in the correct directory, to which all accounts have R/W access. However when I run the Java SE embedded 8 install, it falis to install with the message “I was expecting the file /volume1/public/ejdk-8u6-fcs-b23-linux-arm-sflt-12_jun_2014.tar.gz etc….
    Any ideas? – thanks for the help in advance.

    struggling to install java embedded on my ds214, tried different versions of java 6, 7, 8 none recognizes the package on the public folder even if the file name is exactly the same as it is asking for. tried with java installer app with the same result. public folder is shared with permissions for all kinds for all users, tried downloading the packages with different browsers, nothing helps… any idea?

      Have you tried with Firefox? I think it’s the only browser that leaves the file alone and doesn’t try to rename it or unpack it.

        I tried first with firefox but it removed tar compression, then i tried IE which did not touch the file, at least its name

      2. mohammedslimani

        Works for me with Chrome on MacOS. I tried with Java 7 as suggested by Patters and it just works again… Don’t as me why, cause I’ve already tested with Java7 with a lot of errors :)

    Hi,
    thank you for your work on this, it’s a great guide.
    I have a fresh Synology EDS14 (Armada 370) which I am trying to get Java 6 or 7 running on using your method, however I am unsuccessful.
    Despite placing the correct files into the correct folder, ensuring the appropriate file permissions, etc I get the error:
    “Operation Failed. I was expecting the file….”.
    I originally attempted this with the EDS14 running DSM 4.3 but then upgraded to DSM 5 with the same results.
    The only other thing I can add is that the EDS14 uses external storage so uses variable volume labels like this:
    “/volumeUSB2/usbshare/@sharebin/public”.
    Despite this, the “Operation Failed” error message tells me it is looking in the correct location for the files.

    Any idea on how to get this to go?

      I should add, I have tried downloading the files using (windows based) Firefox, chrome and IE. Firefox and IE do not modify the file name, chrome does.

      I have also tried to upload the files using the Synology File Station GUI and through WinSCP.

      As mentioned above, the path and file names in the error match exactly to the files that exist.

      Permissions are set to R/W for everyone.

      I don’t know what else to do!

    I am trying to setup Java on my DS713+ I downloaded jdk-7u67-linux-i586.tar.gz. When I try to open the file the message unsupported file format pops up. What could go wrong. I downloaded the file with chrome but I noticed the filename did not change.

    HI Patters,
    Let’s say i would like to change the release of Java 7u60 back to 7u55. Will it break my current crashplan setup, or shall i need to reinstall Crashplan after on. Reinstallaing crashplan and “adopting” takes several hours on the server side to resynchronise archive. thanks for your help. Any

        Hi patters, thank you for your kind reply. Well, i have a DS213+ hence 512 Mb RAM, and i was able to backup about 1,1 Gb without any RAM issue and limiting the number of files. I have observed that crashplan is constantly restarting when backing up files (about every 3-4 minutes) , and i was not able to see any mention to out of memoty errors on the engine logs, everything seems ok appart the constants restarts. I observed this behaviour since release 1.7.60 of JAVA. i did not change the file size or selection since: I am tending to believe that this java release is the cause, but i also realised that i cannot rollback, since i also rely on your java 7 package, and i am not senior enough to proceed manually.

    Thank you so much for putting this together – it’s awesome! I have this running with my DS213 and it’s working perfectly!

    I have a question for you, “UPDATE 3” says Java 8 support was added but the guide links to and says to use “Java SE for Embedded 7”. Should I still use Java SE for Embedded 7 (instead of 8)?

    Thanks again for the awesome guide!

    Hi,
    On my Synology DS112J, is was running DSM 4.3 with Java SE Embedded 7, with no problem. Recently, I upgraded my NAS to DSM 5.0-4493 update 3 and I re-install Java SE Embedded 7.
    Now I have a problem with UTF-8 and locale support.

    – With the” locale-a” command I have :
    locale: Cannot set LC_CTYPE to default locale: No such file or directory
    C
    cs_CZ.utf8
    da_DK.utf8
    de_DE.utf8
    en_US.utf8
    es_ES.utf8
    fr_FR.utf8
    hu_HU.utf8
    …

    – I try the “localedef -c -f UTF-8 -i en_US en_US.UTF-8” command and the result is :
    /usr/share/i18n/charmaps No such file or directory

    I have also installed Java SE Embedded 8 and i have the same problem.

    Have an idea ?

    Thanks for all

      Hi,
      I think that The DSM upgrade was not (fully) correct.
      So, I reset my DS112j with complete DSM 5.0 firmware and the problem was solved.
      Thanks everyone.

    on DS110j, Java 8 installs withouot any problem.
    However, I want to install Bliss, which is linked to Java6.
    But, Java6 is impossible to install.
    I’ve downloaded the correct file, put it in public shared folder.
    Log file for Java6 says :
    /var/packages/java6/scripts/start-stop-status: /var/packages/java6/scripts/start-stop-status.sh: line29: java: not found
    …
    UTF8 stuff
    …
    JAVA_HOME=

    Hi,

    i installed the e500v2 package from Oracle, through your Syno package and using a public directory.
    Problem is Filebot won’t launch, saying “/usr/syno/bin/filebot : line 35 : java not found”.
    I would appreciate some help to finish the config of my DS413 running DSM 5.0 -4493 Update 5″.

    Thank you

    I just upgraded from a DS412+ to DS415+. This package worked great for my DS412+.
    I installed Java 7u60 fine. When I add http://packages.pcloadletter.co.uk/ to package sources, I’m only able to see packages for “noarch”, so crashplan is not an option. Is/will it be possible to use this package for the DS415+ / avoton arch processor?

    So I was troubleshooting why my 1513+ was sitting at 89-90% memory utilization and found that the Java embedded package is literally consuming 1.53GB of memory. I’m using the Java 8 embedded strictly for your CrashPlan service to run. So I disabled the last version of the Java 8 embedded and got the latest version from Oracle’s site, installed it, re-enabled crashplan (which is working fine) and sure enough it went right back up to 89-90% memory utilization with Java being the memory hog again. Is there something that can be done here? It’s causing my NAS to run sluggish.

      CrashPlan loves RAM. I guess you could use the Task Scheduler and schedule the CrashPlan service to only run from say 02:55 to 04:00 each day. (03:00 is when CP’s full maintenance scan runs by default to find new or changed files).
