Java 7(1.7) Security Exceptions - How To

From the Oracle Java Support site..
Starting with Java 7 Update 51, trying to run Java applications generates messages
-Java applications are blocked by your security settings.
Java has further enhanced security to make the user system less vulnerable to external exploits. Starting with Java 7 Update 51, Java does not allow users to run applications that are not signed (unsigned), self-signed (not signed by trusted authority) or that are missing permission attributes.
Risks involved in running applications
The application that you are running is blocked because the application does not comply with security guidelines implemented in Java 7 Update 51.
Contact the developer or publisher of this application and let them know about the application being blocked. You can refer them to these links that provide information about implementing secure practices in the code for the application.
JAR File Manifest Attributes for Security
It is highly recommended not to run these types of applications. However if you still want to run these apps, run 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.
Steps to Add URLs to the Exception Site list
Add url to Exception Site list
If the URL where the applet is hosted is different from the URL of the web page from which the applet is launched, then you will need to add both the URL for the applet as well as the URL for the web page.
Example with different URLs for the applet and the web page
Click OK to save the URL that you entered
