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 The Java 6 package has been withdrawn from the package repository for this reason.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

    Trying to get this running on a Synology 212j with DSM 5.1. My public folder is empty, I’ve added the repo, and when I attempt to install Java SE Embedded 7 I just get the error message “Failed to install “Java SE Embedded 7.” But no other info like which package I should upload to the public folder. I’ve tried all the current ARM headless packages and nothing seems to be working. Any thoughts? Is it because of DSM 5.1?

        The CrashPlan and Java packages are now signed by Synology with my key, and my repo is currently pushing this key (see it in Certificates tab of Package Center Settings). So once all my packages have been signed I advise you set the trust level to “Synology Inc. and Trusted Publishers”.

        Can’t reply on the answer of patters belwu, but you should mention this in the description. It’s kind of obvious that you need to allow the installer to actually install, but I didn’t know this setting existed and therefor lost an hour trying to figure out why it didn’t work. Or perhaps improve the error message ?

    hi Patters
    so pb starting to try the install of java 6 for a Ds415+ (intel atom)…
    1) using DSM 5.1-5022 Update 2
    2) activation of “service d’accueil utisisateur” in user menu – advanced (should be the user home service)
    3) creation of public folder (admin user has all access)
    4) download of jre 6 for intel, name same as in your script ejre-1_6_0_38-fcs-b05-linux-i586-headless-13_nov_2012.tar.gz
    5) adding your url for custom packets downloads
    6) click on java6 icon for install
    it recognize the package, but when i click apply, i have the error: “echec de l’installation de java se embedded 6”
    Do you have an idea or am I doing wrong somewhere?

    Hi,

    I’m having problems installing the Java 8 version of the package.

    I can’t seem to find the right oracle download. I’ve tried several and keep getting told that the file format is invalid when I try to install the package.

    Also I was wondering if it’s possible to install Java 8 and still have Java 7 installed via the Synology Java Manager, since I think some other packages (Crashplan for example) don’t like Java 8. I’m trying to run both Crashplan and filebot.

    Do you have any suggestion how to solve this problem?

    Hi there,

    I read in your explanation that “I also added locale support to the underlying Linux since Java requires this for UTF-8 support when reading from the filesystem.”.
    Could you be more specific on this ? (howto :-p )

    I actually am struggling with a crashplan install on a freeNas. Crashplan works but it has problem with non POSIX character sets (it actually ignores accentuated filenames). After some long research i believe the problem comes from the java itself (running on some linux compatibility layer) and stumbled on this post.

    For the moment the java version used is linux-sun-jre1.7.0

    Tx !

    I updated to DSM 5.2 today and cannot get CrashPlan to run. Usually this is resolved by reinstalling Java 8 and the CrashPlan package. However, this time no luck. It appears that CrashPlan starts, but then attempts (unsuccessfully) to download and install an upgrade, then comes to a complete halt. Log screenshot (or link to image) is below. Any suggestions for resolving this?

    Hi Patters,

    Since DSM5.2, I think there is a timezone TZ problem, applications running with Java are 2 hours late (Openhab, here in France)
    It seems it comes from there in start-stop-status.sh :

    SYNO_TZ=`grep “^${SYNO_TZ}” /usr/share/zoneinfo/Timezone/tzname | sed -e “s/^.*= //”`

    tzname doesn’t exist anymore, replaced by tzlist.

    Possible ?

    Thanks for the good job,

        I had the same issue, with my times being ~6-7 hours off (can’t remember, I’m in CDT). The Java package install didn’t have any value in it’s log for TZ=
        I manually made the change suggested above. When SSHed into my Synology, the “date” command shows the proper date & time. However, CrashPlan thinks the time is 1 hour earlier than the actual time (i.e. 8PM instead of 9PM). Any idea what I goofed up?

        I adjusted the start-stop-status.sh as described and replaced “tzname” by “tzlist” – anyway openhab is one hour behind, it seems that the daylight saving time is not considered, via osgi console I always get “GMT+1” for TZ String = “CET-1CEST,M3.5.0,M10.5.0/3″ (I also entered SYNO_TZ=”CET-1CEST,M3.5.0,M10.5.0/3” as fixed value in the start script – any idea what might cause Java not to calculate DST time correctly?

    So in reading the changelog for the package, it’s no longer necessary to re-install it when DSM updates? DSM 5 has locale support built in? I’m a little vague on how to *re-install* a package, unless it’s remove it and install it again.

  28. Marc Wilson's avatarMarc Wilson

    Well, let me clarify that… I applied the latest CrashPlan pacakge, and then CP started posting log entries that made it look like the timezone was screwed. So I updated the Java package, and now the log thinks I’m a hour behind what the clock actually is.

    The Synology itself has the right date and time.

    Do I need to download a new Java binary from Oracle when updating the package? It didn’t tell me to, and didn’t ask to put it in the public share, either.

    Reply ↓
    1. patters's avatarpatters Post author

      No, there’s no need for a new Java. It was an issue with an environment variable. My CrashPlan is also one hour out. Which timezone are you actually in?

    @ussohio

    Did you find a resolution? Mine is *populating* the TZ variable correctly with ‘PST8PDT’, but I’m still one hour behind in the CrashPlan log.

    @carsten’s comment above also seems relevant.

      Resolution? I’m not a Java (or a Linux) expert. I worked around it by moving all my times an hour. :) I did, however, uninstall Java 7 on my DS213 and install Java 8. It didn’t change anything. This is what I currently have:

      Java 1.8.0_33 from patters (THANKS!!!), using Java SE build 1.8.0_33-b05, headless
      TZ=CST6CDT,M3.2.0,M11.1.0
      CrashPlan 4.3.0-0033 from patters (THANKS AGAIN!!!)

      SSH’ing into my DS213 and issuing the ‘date’ command gives me the correct time:
      Mon Jul 13 20:01:41 CDT 2015

      Starting the CrashPlan package shows me the Java/CrashPlan time:
      7/13/15 7:01 PM CrashPlan started, version 4.3.0, GUID xyz….

      If somebody has an idea to try, I’m all ears. I think everything will resolve itself in the fall (I’m sure this is daylight savings time related) and reoccur in the spring. :)

      Stop CrashPlan. Uninstall Java (this won’t affect CrashPlan since it’s not actually running). Install the updated Java (see instructions on blog post). Start CrashPlan. Easy!

      Looking more closely at this I am stumped. My scripts do not use this location so I don’t know where this command is coming from. I can only suppose that it’s some generic Package Center process inspecting the .spk file (which is a TAR archive) looking for a file called conf (not sure this is in the current published specification). It may be an unimportant error.
