Step 9: Upgrade the Java Plug-in on Discoverer Installation

Note:
This step is required to prevent an error about using an older Java Plug-in version each time Discoverer Plus is called from within E-Business Suite.
The Operating System chosen for the download is that of the clients i.e. Windows

1) Download the latest plug-in from Sun Microsystems using the following URL:
http://java.sun.com/javase/downloads/index.jsp
Download the JRE file e.g. jre-6u16-windows-i586.exe
2) Copy the file to the Server and save in the following folder:
$ORACLE_HOME/jpi/bin
Rename the file to something more sensible e.g. jre6u16.exe
3) Edit the file $ORACLE_HOME/discoverer/config/configuration.xml
Search for the line starting with Java > General Tab
b. Press Setting in “Temporary Internet Files” Section
c. Press the Delete Files button
d. Ensure all options is selected and press OK
2. In Internet Explorer
a. From the Tools Menu, click on Delete Browsing History
b. Navigate to: Tools > Manage Add-ons > Enable or Disable Add-ons
Delete all Java Plug-ins for all the viewing options
Note: There will be some that can’t be deleted
c. Close the browser
3. On Windows
a. Navigate to: Control Panel > Add or Remove Programs
b. Delete all programs listed with Java in the name.
4. Retry Discoverer Plus and E-Business Suite. You should be prompted to download some ActiveX Controls
