I'm getting the notifications from Oracle about a new certification products.
One of the notification is New Java version certification for EBS.
There was a link to previous java versions in www.oracle.com.
Right now all Java versions can be downloaded from All Java SE Downloads on MOS (Doc ID 1439822.1)
For example , you want to download jre-6u81-windows-i586.exe:
This patch include JDK and JRE.
Just download it and install the relevant.
Good Luck ...
