Download the jLog application for Linux

The installer and optional files are available under these License conditions:

V 5.4.5

jLog installer program installer.jar installer.jar
Release notes README README

Please note that the author of jLog will only test Linux versions of jLog on Linux Mint 16 x64 and Ubuntu Linux 14.04 LTS x64.
jLog may also support other versions...


  1. jLog V 5.0 and earlier: Unless already installed, please install the Java Runtime Environment and the RXTX serial communications package before installing the jLog application.

    jLog V 5.1 and newer: Unless already installed, please install the Java Runtime Environment.
    Please note that RXTX has been replaced by the built-in PureJavaComm and RXTX must be removed from the Java version to be used by jLog.
  2. Log in as the preferred user and download the installer program that corresponds to the selected version of jLog.
  3. For jLog V 5.x (and assuming Linux Mint 14 or 15, Ubuntu 12 or 13 (or similar):

    Download the installer.jar file. Then, make sure that the file is executable by right-clicking and selecting Properties. Under Permissions, check the 'Allow executing the file as program' and close the Properties dialogue.

    Start the installaller by right-clicking the installer file, then clicking "Open With OpenJDK Java 7 Runtime".
    This should start the jLog Installer. Use the default values unless you are very confident with Linux.

    You should find the installed jLog, either in a "jLog5" folder at the top-level of the Start Menu, or in the "Other" folder.
    Once found, you may right-click jLog and pin it to the Start Menu or the Taskbar.

  4. For Ubuntu 12/13 using Unity: An installer bug will make jLog not visible in the Start Menu.
    Open the Terminal and type:
    $ cd .local/share/applications
    $ chmod a+x jLog*
    Then, logout and login again. jLog should now be visible in the Start menu.

    For jLog V 4.x (or generally):

    Make sure that the logged in user can reach the Java (JRE) previously installed by opening a Terminal window ("shell") and typing:

    $ echo $PATH
    Inspect the output. If Java is not found in the PATH, please enter (assuming that the Java JRE was placed in: '/usr/java/', substitute if different):

    $ PATH=$PATH:/usr/java/j2re1.6.0_04/bin; export PATH
    $ echo $PATH
    Please verify that Java is found in the PATH by re-entering 'echo $PATH'

    After this or in case the previous attempt  was unsuccessful, start the installation by typing:

    $ cd  <the directory where you placed the installer>
    $ sh ./install.bin or for jLog V 5: $ java -jar installer.jar

  5. To increase log capacity beyond 25000 - 30000 entries per file, you must change the Java VM properties.

  6. Note that the default UTF-8 environment in SuSE V 9+ must be changed to e.g. ISO-8859-1. See changing charset.
