Hi Nikhil,
Please upgrade to latest JRE version.
And then follow these steps -
1. Open Control Panel --> Programs --> Java
2. Go to Security Tab
3. In the Exception Site List Section, Click on Edit Site List Button.
4. Add the SAP MII URL which consists of IP and port.
5. After Adding the URL, click on Add button you will get an exception, click on continue
6. After that Click OK. Java Console gets closed.
7. Now try to access the MII application which are having applets. Only for the first time you will get the below pop-up. Check the Check-box.
8. From Next time on wards, you will not see the security pop-up neither when you're opening workbench nor running a MII application which consists of applets.
Versions used for testing above Scenario -
MII - 15.0 SP3 Patch 0
JRE - Version 8 Update 45
Hope this helps! Please let me know if there are any issues/concerns.
Regards,
Sai Vellanki.
