Unable to open forms after fresh installation of EBS 12.1

We installed EBS 12.1 and when we tried to open forms in IE11, it threw an message "In order to access this application, you must install the J2SE Plugin version 1.5.0_13. 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 ".


The steps we performed to resolve the issue are:

1. Go to tools>compatibility settings>and add the domain. My domain was oracle.com so i added it.
2. Tools>internet options>security>internet>custom level>disable xss filter
3. Under internet options>security>Local Intranet>sites>advance option>added the site http://ebs1.oracle.com
4. internet options>security>Local Intranet>custom level>disable xss filter
4. The final step was to apply the RPM-openmotif21-2.1.30-11.EL5.i386.rpm, Shut down ebs services including database and install the RPM. Once installed, start the services and test it.
