8.4 Configuring PDF Generator

If you installed PDF Generator as part of your LiveCycle, complete the following tasks:

    8.4.1 Environment variables

    If you installed the PDF Generator module and configured it to convert files to PDF, for some file formats, you must manually set an environment variable that contains the absolute path of the executable that is used to start the corresponding application. The table below lists the environment variables for the native applications that you have installed.

    Note: Ensure that the required applications are installed on all nodes in the cluster.
    Note: All environment variables and respective paths are case-sensitive.

    Application

    Environment variable

    Example

    Adobe Acrobat

    Acrobat_PATH

    C:\Program Files (x86)\Adobe\Acrobat 10.0\Acrobat\Acrobat.exe

    Adobe FrameMaker®

    FrameMaker_PATH

    C:\Program Files (x86)\Adobe\FrameMaker7.1\FrameMaker.exe

    Notepad

    Notepad_PATH

    C:\WINDOWS\notepad.exe

    You can leave the Notepad_PATH variable blank.

    OpenOffice

    OpenOffice_PATH

    C:\Program Files (x86)\OpenOffice.org 3

    Adobe PageMaker®

    PageMaker_PATH

    C:\Program Files (x86)\Adobe\PageMaker 7.0\PageMaker.exe

    WordPerfect

    WordPerfect_PATH

    C:\Program Files (x86)\WordPerfect Office 12\Programs\wpwin12.exe

    Adobe Photoshop®

    Photoshop_PATH

    C:\Program Files (x86)\Adobe\Adobe Photoshop CS4\Photoshop.exe
    Note: These environment variables must be set for all nodes in the cluster.
    Note: The environment variable OpenOffice_PATH is set to the installation folder instead of the path to the executable.

    You do not need to set up the paths for Microsoft Office applications such as Word, PowerPoint, Excel, Visio, and Project, or for AutoCAD. The Generate PDF service starts these applications automatically if they are installed on the server.

    Create a new Windows environment variable

    1. Select Start > Control Panel > System.

    2. Click the Advanced tab and click Environment Variables.

    3. In the System variables section, click New.

    4. Enter the environment variable name you need to set (for example, enter Photoshop_PATH). This folder is the one that contains the executable file. For example, type the following path:
      D:\Program Files\Adobe\Adobe Photoshop CS4\Photoshop.exe

    Set the PATH variables on Linux or UNIX (OpenOffice only)

    Execute the following command: 

    export OpenOffice_PATH=/opt/openoffice.org3

    8.4.2 Configuring the application server to use HTTP proxy server

    If the computer that LiveCycle is running on uses proxy settings to access external web sites, the application server should be started with the following values set as Java virtual machine (JVM) arguments: 

        -Dhttp.proxyHost=[server host] 
    -Dhttp.proxyPort=[server port]

    Complete the following procedure to start your application server with HTTP proxy host setting.

    1. In the WebSphere Administrative Console navigation tree, Log in to WebSphere Administrative Console, click Servers > Server Types > WebSphere application servers, and then click the name of the server instance to configure (for example, server1)

    2. Under Server Infrastructure, click Java and Process Management > Process Definition.

    3. Under Additional Properties, click Java Virtual Machine > Custom Properties.

    4. Click New and, in the Name box, type http.proxyHost.

    5. In the Value box, type the host name or IP address of your HTTP proxy server and then click OK.

    6. Click New and, in the Name box, type http.proxyPort.

    7. In the Value box, type the port number of your HTTP proxy server and then click OK.

    8. In the Messages box, click Save directly to master configuration.

    9. Restart all WebSphere server instances.

    8.4.3 Setting the Adobe PDF Printer as the default printer

    You must set the Adobe PDF Printer to be the default printer on the server. If the Adobe PDF Printer is not set as the default, PDF Generator cannot convert files successfully.

    For clusters, you must set Adobe PDF Printer as the default printer on all nodes.

    Set the default printer

    1. Select Start > Printers and Faxes.

    2. In the Printers and Faxes window, right-click Adobe PDF and select Set as Default Printer.

    8.4.4 Configuring Acrobat Professional (Windows-based Computers Only)

    Note: This procedure is required only if you upgraded to or installed Acrobat after you completed the LiveCycle installation. Upgrading Acrobat can be completed after you run Configuration Manager and deploy LiveCycle to the application server. Acrobat Professional root directory is designated as [Acrobat root]. Typically, the root directory is C:\Program Files\Adobe\Acrobat 10.0\Acrobat.

    Configure Acrobat for use with PDF Generator

    1. If an earlier version of Acrobat is installed, uninstall it by using Add or Remove Programs in the Windows Control Panel.

    2. Install Acrobat X Pro by running the installer.

    3. Navigate to the additional\scripts folder on the LiveCycle installation media.

    4. Run the following batch file. 

      Acrobat_for_PDFG_Configuration.bat [LiveCycle root]/pdfg_config
      Note: On clusters, you must run the command on the cluster node where LiveCycle is installed.

    5. Open Acrobat and select Help > Check for updates > Preferences.

    6. Deselect Automatically check for Adobe updates.

    Validate the Acrobat installation

    1. Navigate to a PDF file on your system and double-click it to open it in Acrobat. If the PDF file opens successfully, Acrobat is installed correctly.

    2. If the PDF file does not open correctly, uninstall Acrobat and reinstall it.

    Note: Ensure that you dismiss all the Acrobat dialog boxes that are displayed after the Acrobat installation is completed and disable the automatic updates for Acrobat. Set the Acrobat_PATH environment variable to point to Acrobat.exe (For example, C:\Program Files\Adobe\Acrobat 10.0\Acrobat\Acrobat.exe).

    Configure native application support

    1. Install and validate Acrobat as described in the previous procedure.

    2. Set Adobe PDF printer as the default printer.

    8.4.5 Configuring user accounts for multi-threaded file conversions

    By default, PDF Generator can convert only one OpenOffice, Microsoft Word, or PowerPoint document at a time. If you enable multi-threaded conversions, PDF Generator can convert more than one of the documents concurrently by launching multiple instances of OpenOffice or PDFMaker (which is used to perform the Word and PowerPoint conversions).

    Note: Only Microsoft Word 2007 and Microsoft PowerPoint 2007 are supported with multi-threaded file conversions. Microsoft Excel 2003 or 2007 versions are not supported.

    If you need to enable multi-threaded file conversion, you must first perform the tasks outlined in the “Enabling multi-threaded file conversions” section of the Preparing to Install or Upgrade guide available on the LiveCycle documentation.

    For Linux and Solaris users, you must create users and configure the system to remove the password prompts. The following section outlines the method to create a user and perform additional configurations.

    8.4.5.1 Add user account

    1. In Administration Console, click Services > LiveCycle PDF Generator ES3 > User Accounts.

    2. Click Add and enter the user name and password of a user who has administrative privileges on the LiveCycle Server. If you are configuring users for OpenOffice, dismiss the initial OpenOffice activation dialogs.

      Note: If you are configuring users for OpenOffice, the number of instances of OpenOffice cannot be greater than number of user accounts specified in this step.

    3. Restart the LiveCycle Server.

    Note: Ensure that the added user account is defined for all the nodes of the cluster.

    8.4.5.2 Additional configuration required for OpenOffice on Linux or Solaris

    1. Add user accounts as described above.

    2. Add entries for additional users (other than the administrator who runs the LiveCycle Server in the /etc/sudoers file. For example, if you are running LiveCycle as a user named lcadm on a server named myhost, and you want to impersonate user1 and user2, add the following entries to /etc/sudoers:
      lcadm myhost=(user1) NOPASSWD: ALL 
lcadm myhost=(user2) NOPASSWD: ALL

      This configuration enables lcadm to run any command on host ‘myhost’ as ‘user1’ or ‘user2’ without prompting for password.

    3. Allow all the users that you added via Add a user account to make connections to the LiveCycle Server. For example, to allow a local user named user1 the permission of making the connection to the LiveCycle Server, use the following command:

      xhost +local:user1@

      For more details, refer to xhost command documentation.

    4. Restart the server.

    8.4.6 Installing East Asian characters in Windows Server 2003

    When HTML files are converted to PDF by using PDF Generator, some East Asian languages, such as Japanese, Korean, and Chinese, and also right-to-left languages, such as Arabic, Armenian, Georgian, Hebrew, Indic, Thai, and Vietnamese, may not be displayed in the PDF file.

    To ensure that these languages are displayed in Windows Server 2003, appropriate fonts must be present on the client and server.

    Install East Asian characters in Windows Server 2003

    1. Select Start > Control Panel and open Regional and Language Options.

    2. Click the Languages tab and select Install Files for East Asian Languages.

    3. Click the Advanced tab and select all the options under Code Page Conversion Tables.

    If converted PDF files are still missing fonts, verify that the Arial Unicode MS (TrueType) font (ARIALUNI.TTF) is present in the C:\WINDOWS\Fonts directory.

    8.4.7 Adding fonts to PDF Generator

    LiveCycle provides a central repository of fonts, which is accessible to all LiveCycle modules. Make the extra fonts available to non-LiveCycle applications on the server so that PDF Generator can use these fonts to create PDF documents that are created with these applications.

    Note: Restart the application server after adding new fonts to the specified fonts folder.

    8.4.7.1 Non-LiveCycle applications

    The following list contains non-LiveCycle applications that PDF Generator can use for PDF generation on the server side:

    Windows-only Applications

    • Microsoft Office Word

    • Microsoft Office Excel

    • Microsoft Office PowerPoint

    • Microsoft Office Project

    • Microsoft Office Visio

    • Microsoft Office Publisher

    • AutoDesk AutoCAD

    • Corel WordPerfect

    • Adobe Photoshop CS

    • Adobe FrameMaker

    • Adobe PageMaker

    • Adobe Acrobat Professional

    Multiplatform applications

    • OpenOffice Writer

    • OpenOffice Calc

    • OpenOffice Draw

    • OpenOffice Impress

    Note: In addition to these applications, your list may include additional applications that you added.

    Of the above applications, the OpenOffice Suite (which includes Writer, Calc, Draw, and Impress) is available on Windows, Solaris, and Linux platforms, whereas other applications are available on Windows only.

    8.4.7.2 Adding new fonts to Windows applications only

    All the Windows-only applications that are mentioned above can access all the fonts that are available in the C:\Windows\Fonts (or equivalent) folder. In addition to C:\Windows\Fonts, each of these applications may have its own private fonts folders.

    Therefore, if you plan to add any custom fonts to the LiveCycle fonts repository, ensure that the same fonts are available to the Windows-only applications also by copying these fonts to either C:\Windows\Fonts or to an equivalent folder.

    Your custom fonts must be licensed under an agreement that allows you to use them with the applications that have access to these fonts.

    8.4.7.3 Adding new fonts to other applications

    If you added support for PDF creation in other applications, see the Help for these applications to add new fonts. In Windows, copying your custom fonts to the C:\Windows\Fonts (or equivalent) folder should be sufficient.

    8.4.8 Configuring HTML to PDF conversions

    The HTML-to-PDF conversion process is designed to use the settings from Acrobat X that override the settings from PDF Generator.

    Note: This configuration is required to enable the HTML-to-PDF conversion process, otherwise this conversion type will fail.

    8.4.8.1 Configure the HTML-to-PDF conversion

    1. Install and validate Acrobat as described in 8.4.4 Configuring Acrobat Professional (Windows-based Computers Only).

    2. Locate the pdfgen.api file in the [LiveCycle root]\plugins\x86_win32 directory and copy it to [Acrobat root]\Acrobat\plug_ins directory.

    8.4.8.2 Enable support for Unicode fonts in HTML to PDF conversions

    Important: The HTML-to-PDF conversion fails if a zipped input file contains HTML files with double-byte characters in filenames. To avoid this problem, do not use double-byte characters when naming HTML files.

    1. Copy the Unicode font to any of the following directories as appropriate for your system:

      • Windows

        [Windows root]\Windows\fonts

        [Windows root]\WINNT\fonts

      • UNIX

        /usr/lib/X11/fonts/TrueType

        /usr/openwin/lib/X11/fonts/TrueType

        /usr/share/fonts/default/TrueType

        /usr/X11R6/lib/X11/fonts/ttf

        /usr/X11R6/lib/X11/fonts/truetype

        /usr/X11R6/lib/X11/fonts/TrueType

        /usr/X11R6/lib/X11/fonts/TTF

        /Users/cfqauser/Library/Fonts

        /System/Library/Fonts

        /Library/Fonts

        /Users/ + System.getProperty(<user name>, root) + /Library/Fonts

        System.getProperty(JAVA_HOME) + /lib/fonts

        /usr/share/fonts (Solaris)

      Note: Ensure that the directory /usr/lib/X11/fonts exists. If it does not, create a symbolic link from /usr/share/X11/fonts to /usr/lib/X11/fonts using the ln command.

    2. Modify the font-name mapping in the cffont.properties file located in the [LiveCycle root]/deploy/adobe-generatepdf-dsc.jar file:

      • Extract this archive, and locate the cffont.properties file and open it in an editor.

      • In the comma-separated list of Java font names, add a map to your Unicode system font for each font type. In the example below, kochi mincho is the name of your Unicode system font.

        dialog=Arial, Helvetica, kochi mincho

        dialog.bold=Arial Bold, Helvetica-Bold, kochi mincho ...

      • Save and close the properties file, and then repackage and redeploy the adobe-generatepdf-dsc.jar file.

      Note: On a Japanese operating system, specify the font mapping in the cffont.properties.ja file as well, which takes precedence over the standard cffont.properties file.
      Fonts in the list are searched from left to right, using the first font found. HTML-to-PDF conversion logs return a list of all the font names that are found in the system. To determine the font name you need to map, add the font to one of the directories above, restart the server, and run a conversion. You can determine from the log files the font name to use for mapping.

      To embed the font in the generated PDF files, set the embedFonts property in the cffont.properties file to true (the default is false).

    8.4.9 Modify Microsoft Visio default macro settings

    When a Microsoft Visio file containing macros is submitted for conversion, the resultant Microsoft Office Visio Security Notice dialog causes the conversion to time out. To successfully convert files that contain macros, the default macro settings in Visio must be changed.

     In Visio, click Tools > Trust Center > Macro Settings and select either of the following options and then click OK:

    • Disable all macros without notification

    • Enable all macros

    8.4.10 Installing the Network Printer Client

    PDF Generator includes an executable file to install the PDF Generator network printer on a client computer. After the installation is complete, a PDF Generator printer is added to the list of existing printers on the client computer. This printer can then be used to send documents for conversion to PDF.

    Note: The Network Printer Client installation wizard available in the Administration Console is supported only on Windows operating system. Ensure that you use a 32-bit JVM to launch the Network Printer Client installation wizard. You will encounter an error if you use a 64-bit JVM.

    If the PDFG Network Printer fails to install on Windows or if you want to install the printer on UNIX or Linux platforms, use the operating system’s native Add Printer utility and configure it as described in 8.4.10.2 Configure PDFG Network Printer on Windows using the native Add Printer wizard

    8.4.10.1 Install the PDF Generator Network Printer Client

    Note: Before installing the PDF Generator network printer client on Windows Server 2008, Ensure that you have the Internet Printing Client feature installed on your Windows Server 2008. For installing the feature, see Windows Server 2008 Help.

    1. Ensure that you successfully installed PDF Generator on your server.

    2. Do one of the following:

      • From a Windows client computer, enter the following URL in your web browser, where [host] is the name of the server where you installed PDF Generator and [port] is the application server port used:

      Note: The user credentials used while adding the printer must have a valid email ID configured in User Management to receive the response.

    7. Configure the email service’s sendmail service. Provide a valid SMTP server and authentication information in the service’s configuration options.

    8.4.10.3 Install and configure the PDF Generator Network Printer Client using Proxy server port forwarding

    1. Configure port forwarding on the CC Proxy server on a particular port to the LiveCycle Server, and disable the authentication at proxy server level (because LiveCycle uses its own authentication). If a client connects to this Proxy server on the forwarded port, then all the requests will be forwarded to the LiveCycle Server.

    2. Install PDFG Network Printer using the following URL: 

      http://[proxy server]:[forwarded port]/pdfg-ipp/install.

    3. Provide the necessary credentials for authentication of the PDFG Network Printer.

    4. The PDFG Network Printer will be installed on the client machine which you can use for PDF conversion using the firewall protected LiveCycle Server.
