This appendix includes information about using Oracle Fusion Middleware accessibility options. It includes:
If you are installing on a Windows computer, you can install and configure Java Access Bridge for Section 508 Accessibility:
Download Java Access Bridge from the following URL:
http://java.sun.com/javase/technologies/accessibility/accessbridge/
Install Java Access Bridge.
Copy the access-bridge.jar
and jaccess-1_4.jar
files from your installation location to the jre/lib/ext
directory.
Copy the WindowsAccessBridge.dll
, JavaAccessBridge.dll
, and JAWTAccessBridge.dll
files from your installation location to the jre/bin
directory.
Copy the accessibility.properties
file to the jre/lib
directory.
The following sections provide information on the benefits of running Fusion Middleware Control in accessibility mode, as well as instructions for enabling accessibility mode:
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:
Choose Setup, then My Preferences, then Accessibility.
The Accessibility Preference page is displayed.
Select one or both of the following options:
I use a screen reader: Accessibility-specific constructs are added to improve behavior with a screen reader.
Show me the Accessibility Preference dialog when I log in: When you log in, the Accessibility Preference dialog is displayed, with the following options:
I use a screen reader
Do not show me these options again
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.
The following figure shows the navigation pane and the Administration Server Performance Summary after enabling screen reader support:
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.
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.
