Your security settings have blocked a self signed application from running ( window 8 , Java 7 Update 51)

there could be many reason for this error , but I have encountered this error while trying to open Oracle EBS 12.1.3 after I have upgraded my Java 
FROM  Version 7 Update 40 
To  Version 7 Update 51

Well ,  this is a genuine message as Oracle has enhance security feature in Version 7 update 51 . It is highly recommended that we should not run the applications that raised this type of messages , but in my case I am trying to my EBS application which is a safe application. Options that I have - 

1.Contact DBA
2,Use below workaround , and I like option #2 as this is quick one ( but at the same time run these applications only if you understand the risks and implications).


As a workaround, you can use the Exception Site list feature to run the applications blocked by security settings. Adding the URL of the blocked application to the Exception Site list allows it to run with some warnings.

Workaround - 

Steps to Add URLs to the Exception Site list

• Go to the Java Control Panel (On Windows Click Start and then Configure Java)
• Click on the Security tab
• Click on the Edit Site List button
• Click Add in the Exception Site List window

Please note that above workaround works for me , you should evaluate your environment thoroughly before using this work around
