If you encounter a Java applet, and see Application Blocked by Security Settings display, it may be that your system is running an old version of Java. You may use the Exception Site List to run any blocked application. To do, launch your computer’s Java Control Panel, and click the Security tab: Click the Edit Site List button.
I need to use an old Java applet for a certain website, but newer Java versions cannot run it, as it has a self-signed certificate. Reading on Oracle's Deployment Guide, I need to make my own deployment.JAR, with a proper certificate signing (not self signed), just to create the exception I need to run applets from a single domain. I have found that there is a%userprofile% appdata LocalLow Sun Java Deployment security exception.sites file, obviously one for each user. In there, one per line, is a list of domains I can set to exclude from NOT being executed. When I add the domain name, the user gets a single prompt, then it just allows that domain for that user. I know I could add this file to the Default user profile, for any new users being created.
Unfortunately, I do not think that removing every user's profile from each of the systems is the right way to go. I can push commands to computers, but the commands run as my user - I can't use%USERPROFILE% for this. I do not want to put it in my login script, as I do not want the file getting large for users who constantly log in and off of systems. I also only want the single domain added to whatever is there, without wiping out the user's preferences that may already exist.
Because I do not want to wipe out their preferences, I thought of doing something along the lines of echo %userprofile% appdata LocalLow Sun Java Deployment security exception.sites, but that won't work, as it will keep adding to the file. What can I do to add the list to the Exceptions rule, but only if the rule does not exist already?
This document outlines two changes that may be required to use Java applications as a result of the Java 7 update 51 release. After updating to Java 7 update 51 or later, you may need to make a few changes to get it working with certain applications.
The first of these changes is to set the security level to High. The second change is to add the application's URL to the exception list.
Both of these changes can be done in the Java Control panel. The lack of a Java icon in your system preferences indicates that Java is not installed on the machine. You will need to manually install Java by going to Error messages seen if the application's URL is not on the Exceptions list If the application's URL is not added to the Java exception list, one or both of the following errors may be displayed:. Error message seen if the port number is included in the application's URL error: application blocked by Java security This login error is displayed when the port number is included in the URL. Setting the Java Security Level and adding the URL to the Exception List. Go to the Java Control Panel: Windows version. Go to the Control Panel from the Start menu.

If the 'Security Level' is set to 'Very High', reduce it to 'High'. Press the 'Edit Site List' button to get the dialog that will allow you to add the application's URL to the Exception Site List. Press 'Add' to type in the URL.
Note: WAF users will need to update the URL to the Exception Site List by logging into the WAF and then going to: Start Program Files Java Configure Java. On the highlighted line (see arrow # 1), type the application's URL (see for a list of URLs). Click the OK button (see arrow # 2).
When done, the Java control Panel Security tab will look like the graphic in step 2 above if one does not enter any other Exception sites. After launching the application, the 'Do you trust' dialog boxes will still be displayed. To prevent this from happening each time, check the 'Always trust' boxes and click OK.
