B Installing Java Access Bridge (Windows only)

This appendix describes how to install Java Access Bridge on the Windows platform. Java Access Bridge enables use of a screen reader with Oracle components.

This appendix contains these topics:

Section B.1, "What is Java Access Bridge?"
Section B.2, "Setting up Java Access Bridge for use by Installed Oracle Components"

B.1 What is Java Access Bridge?

Java Access Bridge enables assistive technologies, such as JAWS screen reader, 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 Application Server Control.

Your Oracle Business Intelligence installation media contain the Java Runtime Environment (JRE) 1.4.2, which Oracle Universal Installer uses during installation. The JRE enables use of Java Access Bridge during installation. To set up Java Access Bridge for use with JRE 1.4.2 during installation, see Section B.2.1, "Installing Java Access Bridge".

To install and configure Java Access Bridge for use with Oracle Business Intelligence components after installation, see Section B.2, "Setting up Java Access Bridge for use by Installed Oracle Components".

B.2 Setting up Java Access Bridge for use by Installed Oracle Components

This section describes how to install and configure Java Access Bridge for Windows after installing Oracle components. This section contains the following topics:

Section B.2.1, "Installing Java Access Bridge"
Section B.2.2, "Configuring Oracle Components to Use Java Access Bridge"

B.2.1 Installing Java Access Bridge

You can install Java Access Bridge version 1.0.4 from the Oracle Business Intelligence CD-ROM/DVD. Alternatively, you can install Java Access Bridge version 1.2 by downloading the zip file from:

http://java.sun.com/products/accessbridge/

Refer to the Java Access Bridge documentation on the Sun web site for installation instructions and other information.

To install Java Access Bridge from the Oracle Business Intelligence CD-ROM/DVD, follow these steps:

On the Oracle Business Intelligence installation media, go to the following directory.
```
DRIVE_LETTER:\Disk1\AccessBridge
```
Select the accessbridge-1_0_4.jar file and extract its files to the system where you plan to install Access Bridge.

For example:
```
c:\AccessBridge-1_0_4
```

Copy the Java Access Bridge files listed in Table B-1 into the windows_directory\system32 directory.

Table B-1 Files to copy to the system32 subdirectory

Copy	To
\`AccessBridge-1_0_4\installer\installerFiles\JavaAccessBridge.dll`	`windows_directory\system32`
\`AccessBridge-1_0_4\installer\installerFiles\WindowsAccessBridge.dll`	`windows_directory\system32`
\`AccessBridge-1_0_4\installer\installerFiles\JAWTAccessBridge.dll`	`windows_directory\system32`

B.2.2 Configuring Oracle Components to Use Java Access Bridge

You can configure Oracle components to use the Access Bridge after you complete the installation. To do so, you need to set the system variable ORACLE_OEM_CLASSPATH to point to the installed Java Access Bridge files.

B.2.2.1 Configuring for Windows 2000, Windows XP, or Windows Server 2003

To configure Oracle components to use Access Bridge on Windows 2000, Windows XP, or Windows 2003, follow these steps:

Select Start > Settings > Control Panel > System to display the Windows System Control Panel.
Select the Advanced tab.
Click Environment Variables.
Click New under the System Variable list to display the New System Variable dialog.
In the Variable Name field, enter ORACLE_OEM_CLASSPATH.
In the Variable Value field, enter the full path to jaccess.jar and access-bridge.jar.

Use a semicolon to separate the two paths. Do not use quotes or character spaces. For example, if JRE 1.4.2 is installed in the default location, the setting might be:
```
d:\oraclehome1\bihome1\jre\1.4.2\lib\ext\jaccess.jar;d:\oraclehome1\bihome1\jre\1.4.2\lib\ext\access-bridge.jar
```
Click OK.
