Post-installation tasks for Connections PDF Export

PDF Export requires the wkhtmltox binary package in order to render PDF documents. This is a binary dependency that needs to be deployed on your HCL Connections server. The necessary installation steps are outlined below.

You can also leverage available properties to configure PDF Export according to your needs.

Downloading and installing

  1. Download and install the wkhtmltopdf binary package.

    The binary package is available to download here: Please use the latest stable version 0.12.6 for installation.

    Ensure to download the package according to your server operating system. Common examples are listed below, all distributions can be found via above link.

    OS Type
    Windows 64-bit 32-bit
    RHEL 7 / CentOS 7 x86_64 i686 aarch64 ppc64le
    RHEL 8 / CentOS 8 x86_64 aarch64 ppc64le

    Once downloaded, install the package according to your system's requirements.


    rpm -Uvh wkhtmltox-0.12.6-<version>.rpm


    • Download wkhtmltox-0.12.6-<version>.exe

    • Execute binary file to run installer

    • Install tool at appropriate location

  2. Configure the PDF Export feature on WebSphere to leverage wkhtmltopdf binary

    In order for the PDF Export feature to use the wkhtmltopdf library, it needs to be able to invoke the tool via the system's command line. There are two ways to ensure this is the case.

    1. Configure the system path to allow execution of the wkhtmltopdf command.

      PDF Export tries to execute the command

      wkhtmltopdf [args]

      on the system's command line (cmd on Windows, shell/bash on Linux). This can be enabled by adding the wkhtmltopdf to the system's path variable. To test this, try to execute above command on the system's command line. If the command is not recognized, this is not configured correctly. Otherwise PDF Export is now ready and can be used.

      Note: The command needs to be executable by the same user that will start the WebSphere servers/JVMs.

    2. Configure PDF Export to invoke wkhtmltopdf in the correct install location

      If wkhtmltopdf is not available by invoking the command listed in 2.1, you can instead make the PDF Export aware of what execution command is necessary to invoke it instead. For example, if you have installed the feature at location


      you can add this via WebSphere configuration. Perform the following:

      • Enter the WebSphere administrative console (e.g.: and navigate to Resources > Resource Environment > Resource Environment entries

      • Look for the ic360 resource environment entry and click on it

      • Navigate to Additional Properties > Custom properties

      • Click New... to create a new property

      • Enter the name wkhtmltopdf.command.exec and the path to the wkhtmltopdf binary (including its name) as the value, e.g. C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe on Windows or /opt/HCL/Connections/wkhtmltox/bin/wkhtmltopdf on Linux.

      • Click Apply and OK.

      • Save the changes to the master configuration.

      • Restart ICXT server. wkhtmltopdf configuration

      Note: In case of a clustered environment, this library needs to be installed the same way on all nodes of the cluster.

Server side fonts

Without installed fonts, the PDF rendering may result in unsatisfactory result. If there are no font sets installed, we recommend to install DejaVu fonts.

Note: for CentOS or RHEL, the library wqy-microhei-fonts should additionally be installed to support Chinese and Japanese.

  • RHEL or CentOS:

    sudo yum install dejavu-sans-fonts
    sudo yum install wqy-microhei-fonts

    To verify that the Dejavu fonts have been properly installed, run the command fc-list | grep "DejaVu Sans"

    Sample output:

    /usr/share/fonts/TTF/DejaVuSansCondensed.ttf: DejaVu Sans,DejaVu Sans Condensed:style=Condensed,Book
    /usr/share/fonts/TTF/DejaVuSans-BoldOblique.ttf: DejaVu Sans:style=Bold Oblique
    /usr/share/fonts/TTF/DejaVuSansMono.ttf: DejaVu Sans Mono:style=Book
    /usr/share/fonts/TTF/DejaVuSansCondensed-Oblique.ttf: DejaVu Sans,DejaVu Sans Condensed:style=Condensed Oblique,Oblique
    /usr/share/fonts/TTF/DejaVuSansMono-Oblique.ttf: DejaVu Sans Mono:style=Oblique
    /usr/share/fonts/TTF/DejaVuSansCondensed-BoldOblique.ttf: DejaVu Sans,DejaVu Sans Condensed:style=Condensed Bold Oblique,Bold Oblique
    /usr/share/fonts/TTF/DejaVuSans-ExtraLight.ttf: DejaVu Sans,DejaVu Sans Light:style=ExtraLight
    /usr/share/fonts/TTF/DejaVuSans-Oblique.ttf: DejaVu Sans:style=Oblique
    /usr/share/fonts/TTF/DejaVuSansMono-Bold.ttf: DejaVu Sans Mono:style=Bold
    /usr/share/fonts/TTF/DejaVuSansCondensed-Bold.ttf: DejaVu Sans,DejaVu Sans Condensed:style=Condensed Bold,Bold
    /usr/share/fonts/TTF/DejaVuSansMono-BoldOblique.ttf: DejaVu Sans Mono:style=Bold Oblique
    /usr/share/fonts/TTF/DejaVuSans.ttf: DejaVu Sans:style=Book
    /usr/share/fonts/TTF/DejaVuSans-Bold.ttf: DejaVu Sans:style=Bold
  • Windows:

    • The fonts can be found at

    • The documentation at can be used for reference when installing the fonts. Generally, the required steps are:

      • Download and unzip the latest DejaVu fonts ZIP archive

      • Login as Administrator and Click "Start"

      • Search for "run"

      Fonts Windows open Run

      • Enter %windir%\fonts

      Open fonts Config

      Fonts Config

      • Drag and drop the extracted fonts from the ttf folder to the Fonts config window

      Copy fonts

Additional configuration

You can further adjust the PDF Export feature to meet specific requirements using the configuration options listed in ICXT - Configuration parameters.

The following are noteworthy configuration options:

  • icxt.pdfexport.backup.meta.fields to define which content meta information to include in the PDF by default.
  • ic360.pdfexport.previewMode.selected to set the default printing quality of PDFs, either standard quality or reduced quality (referred to as "Preview Mode") for improved performance.

For performance-constrained environments, the property wkhtmltopdf.parallel.processing.limit is useful in limiting the amount of prints that can be simultaneously executed.

Another consideration is which group of users are allowed to print PDFs of specific content, which you can define using icxt.pdfexport.access.requiredrole. By default, users need editing or authoring role on content in order to leverage this feature. You can change it to allow all readers or only content owners to print PDFs of the content.
