E Using Oracle Fusion Middleware Accessibility Options

Oracle Fusion Middleware provides accessibility options, such as support for the use Java Access Bridge, more accessible HTML pages and charts, and keyboard navigation.

Install and Configure Java Access Bridge (Windows Only)

Java Access Bridge is a technology that exposes the Java Accessibility API in a Microsoft Windows DLL, enabling Java applications and applets that implement the Java Accessibility API to be visible to assistive technologies on Microsoft Windows systems.

If you are installing on a Windows computer, you can install and configure Java Access Bridge for Section 508 Accessibility:

  1. Download Java Access Bridge from the following URL:
  2. Install Java Access Bridge.
  3. Copy the access-bridge.jar and jaccess-1_4.jar files from your installation location to the jre/lib/ext directory.
  4. Copy the WindowsAccessBridge.dll, JavaAccessBridge.dll, and JAWTAccessBridge.dll files from your installation location to the jre/bin directory.
  5. Copy the accessibility.properties file to the jre/lib directory.

Enabling Fusion Middleware Control Accessibility Mode

You can make HTML pages of Fusion Middleware Control more accessible and you can more easily view information in charts.

The following topics provide information on the benefits of running Fusion Middleware Control in accessibility mode, as well as instructions for enabling accessibility mode:

Making HTML Pages More Accessible

In Fusion Middleware Control, you can enable screen reader support. Screen reader support improves behavior with a screen reader. This is accomplished by adding accessibility-specific constructs to the HTML, and by altering some navigation elements on the pages.

To enable screen reader mode in Fusion Middleware Control:

  1. Choose the user name at the right top of the page, then Accessibility.

    The Accessibility Preference page is displayed.

  2. Select any of the following options:
    • I use a screen reader: (Accessibility-specific constructs are added to improve behavior with a screen reader.)

    • I use high contrast settings: The fonts use a high contrast.

    • I use large fonts: The fonts are larger than normal.

    • Show me the Accessibility Preference dialog when I log in: When you log in, the Accessibility Preference page is displayed.

  3. Click OK.
  4. Click Enterprise Manager at the top of the page to return to the page you last visited.

When you select screen reader support, Fusion Middleware Control renders the Web pages so that they can be read by a screen reader. For example, each node in the navigation tree includes a Select button.

Viewing Text Descriptions of Fusion Middleware Control Charts

Throughout Fusion Middleware Control, charts are used to display performance data. For most users, these charts provide a valuable graphical view of the data that can reveal trends and help identify minimum and maximum values for performance metrics.

However, charts do not convey information in a manner that can be read by a screen reader. To remedy this problem, you can configure Fusion Middleware Control to provide a complete textual representation of each performance chart. When you enable screen reader mode, Fusion Middleware Control displays the information in tables, instead of charts.

To view a representation of the data in a table, instead of a chart, without enabling screen reader mode, click Table View below a chart.

Fusion Middleware Control Keyboard Navigation

This section describes the keyboard navigation in ­Fusion Middleware Control.

Much of the keyboard navigation is the same whether or not you use screen reader mode.

Generally, you use the following keys to navigate:

  • Tab key: Move to the next control, such as a dynamic target menu, navigation tree, content pane, or tab in a page. Tab traverses the page left to right, top to bottom. Use Shift +Tab to move to the previous control.

  • Up and Down Arrow keys: Move to the previous or next item in the navigation tree, menu, or table. Down Arrow also opens a menu.

  • Left and Right Arrow keys: Collapse and expand an item in the navigation tree or a submenu.

  • Esc: Close a menu.

  • Spacebar: Activate a control. For example, in a check box, spacebar toggles the state, checking or unchecking the box. On a link, spacebar navigates to the target of the link.

  • Enter: Activate a button.

Table E-1 shows some common tasks and the keyboard navigation used.
