A Installing Java Access Bridge

This appendix describes how to install Java Access Bridge, which enables use of a screen reader with Oracle components:

Note:

Java Access Bridge is not supported on Windows x64 for 64-bit database installations.

A.1 Overview of Java Access Bridge 2.0.2

Java Access Bridge 2.0.2 enables assistive technologies to read Java applications running on the Windows platform. Assistive technologies can read Java-based interfaces, such as Oracle Universal Installer and Oracle Enterprise Manager Database Control.

Java Access Bridge 2.0.2 is supported on Windows Server 2008 (32-bit), Windows Server 2008 x64, Windows Server 2008 R2 x64, Windows 7 (32-bit), Windows 7 x64, Windows 8 (32-bit), Windows 8 x64, Windows 8.1 (32-bit), Windows 8.1 x64, and Windows Server 2012 x64 for 64-bit database installations. For a list of supported system configurations, including supported versions of Microsoft Windows and Java SE, see section "Supported System Configuration" available at the following link location:

During installation, Oracle Universal Installer uses Java Runtime Environment (JRE) 1.6 contained in Oracle Database, Oracle Database Client, and Oracle Database installation media. The JRE enables use of Java Access Bridge 2.0.2 during installation. See "Setting Up Java Access Bridge 2.0.2" for information about installing and configuring Java Access Bridge after you install Oracle components.

A.2 Setting Up Java Access Bridge 2.0.2

This section describes how to install and configure Java Access Bridge 2.0.2 for Windows after installing Oracle components.

To set up Java Access Bridge 2.0.2 on a Windows 32-bit and 64-bit operating system, follow these steps:

  1. Go to Java Standard Edition (Java SE) Downloads page to download the latest build of JDK 7:

    http://www.oracle.com/technetwork/java/javase/downloads/index.html

  2. Install JDK 7 after accepting the Oracle license agreement.

    Note:

    You must have administrator privileges to install JDK on Windows.
  3. Press Windows key+U to open the Ease of Access Center, and select Use the computer without a display.

  4. Select Enable Accessbridge check box. Click Save to save the changes.

  5. Download Java Access Bridge 2.0.2:

    http://www.oracle.com/technetwork/java/javase/downloads/jab-2-0-2-download-354311.html

    Download the accessbridge-2_0_2-fcs-bin-b06.zip file, after accepting the Oracle license agreement.

  6. Extract accessbridge-2.0.2 to a directory on your system where you plan to install Java Access Bridge. For example, name the directory as follows:

    AB_HOME
    
  7. Open the command prompt and navigate to one of the directory depending on the type of installation (database, client, or companion) you performed by typing the DRIVE_LETTER:

    To access the files in Disk1 directory, type the following:

    DRIVE_LETTER:\>cd Disk1
    
  8. Run the following command once you are in the Disk1 directory:

    setup.exe -jreLoc path-to-jdk7\jre
    

    Oracle Universal Installer starts and JAWS is able to read all prompts and controls on the screen.

  9. Once you click the Install button, you must open Windows Explorer to see the directory where the database is installed (DRIVE_LETTER:\app\username\product\12.1.0\dbhome_1), until the JDK folder is created. Once the JDK folder is created, you must copy the files listed in Table A-1 and Table A-2 from the Java Access Bridge source location to the JDK destination folder. Copying these files will enable accessibility for both Oracle Database Configuration Assistant and Oracle Net Configuration Assistant.
