E Java Access Bridge Installation

This appendix describes the procedure to install Java Access Bridge. Java Access Bridge enables the use of a screen reader with Oracle components.

This appendix contains the following topics:

• Introduction

• Setup for JRE 1.4.2

• Setup for Oracle Installed Components

E.1 Introduction

Java Access Bridge enables assistive technologies, such as the 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.

The Forms and Reports Services CD-ROMs contain Java Runtime Environment (JRE) 1.4.1 used by Oracle Universal Installer during installation. JRE enables use of Java Access Bridge during installation. To install and configure Java Access Bridge after installing Oracle components, see Section E.3, "Setup for Oracle Installed Components".

E.2 Setup for JRE 1.4.2

To set up Java Access Bridge with JRE 1.4.2, run the following batch file on Oracle installation media.

DRIVE_LETTER:\install\access_setup.bat

After the batch file has run, restart your assistive technology program.

E.3 Setup for Oracle Installed Components

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

• Section E.3.1, "Installing Java Access Bridge"

• Section E.3.2, "Configuring Oracle Components to Use Java Access Bridge"

E.3.1 Installing Java Access Bridge

To install Java Access Bridge:

1. On the Oracle installation media, navigate to the AccessBridge directory.

2. Select the accessbridge-1_0_4.zip file and extract the files to the location where you plan to install Java Access Bridge. For example:

   c:\AccessBridge-1.0.4
   
   

3. Copy the Java Access Bridge files listed in Table E-1 into the JRE 1.4.2 directory used by Oracle components. By default, the JRE used by Oracle components is installed in:

   ORACLE_BASE\ORACLE_HOME\jre\1.4.2
   
   

   Table E-1 lists the files you need to copy from the Java Access Bridge location on your hard drive to the JRE directory used by Oracle components:

   Table E-1 Files to be Copied to JRE Directory

   Copy	To
   \AccessBridge-1_0_4\installer \installerFiles\jaccess-1_4.jar	ORACLE_BASE\ORACLE_HOME\jre\1.4.2\lib\ext
   \AccessBridge-1_0_4\installer \installerFiles\access-bridge.jar	ORACLE_BASE\ORACLE_HOME\jre\1.4.2\lib\ext
   \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
   \AccessBridge-1_0_4\installer \installerFiles\accessibility.properties	ORACLE_BASE\ORACLE_HOME\jre\1.4.2\lib

   
   

4. Rename jaccess-1_4.jar (now located at ORACLE_BASE\ORACLE_HOME\jre\1.4.2\lib\ext) to jaccess.jar.

5. Following a successful installation, you can access the Java Access Bridge documentation located at:

   c:\AccessBridge-1.0.4\doc
   

E.3.2 Configuring Oracle Components to Use Java Access Bridge

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

Configuring for Windows 2000, Windows XP, or Windows Server 2003

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

1. Select Start > Settings > Control Panel > System to display the Windows System Control Panel.

2. Select the Advanced tab.

3. Click Environment Variables.

4. Click New under the System Variable list to display the New System Variable dialog box.

5. In the Variable Name field, enter ORACLE_OEM_CLASSPATH.

6. 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 the quotes or character spaces. For example, if JRE 1.4.2 is installed in the default location, the setting would be:

   c:\oracle\product\10.1.0\Db_1\jre\1.4.2\lib\ext\jaccess.jar;c:\oracle\product\10.1.0\Db_1\jre\1.4.2\lib\ext\access-bridge.jar
   
   

7. Click OK.
