On my machine, I had Java 6 Update 7 installed and forms for R12 were working properly.
But with EBS 11i, I got the follow error when opening a java applet :
"In order to access this application, you must install the J2SE Plugin version 1.6.0_16. To install this plugin, click here to download the oaj2se.exe executable. Once the download is complete, double-click the oaj2se.exe file to install the plugin. You will be prompted to restart your browser when the installation is complete."
I uninstalled Java 6 Update 7 and installed Java 6 Update 16 and Java SE Development Kit 6 Update 16 but error persists.
I am using Internet Explorer 11.
I also have firefox which is showing the same error, firefox doesn't even show Java in browser plugins.
