Java Security Settings Change

Java 7 update 55 Security Settings Change: Windows

With the new Java 7 update 55, Physlets will not run without either (a) lowering the security in the Java Control Panel to Medium or (b) adding the domain of the material into the Java Control Panels list of trusted sites.

1. Go to the Start Menu, then Control Panel, then Programs, then Uninstall a program to uninstall all of the old Java versions you may have.
 

2. Go to the Oracle Java site: http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads-1880261.html

and download the JRE for Windows (both the 32-bit and 64-bit versions).
  

3. Install Java by double-clicking the files you have downloaded.
 

4. In order to lower the security to Medium, navigate to the Start Menu, then Control Panel, then Programs. Click Java and then select the Security tab. Next drag the slider to Medium.
 

5. Now reload a Physlet-based page in your favorite browser. The first time a Physlet loads you will likely get a dialog stating its authenticity, click accept and the do not show this again checkbox. The Physlet should now run.
 

6. In order to add a trusted site, navigate to the Start Menu, then Control Panel, then Programs. Click Java and then select the Security tab.
 

7. Click on the Edit Site List shown above. In the Exception Site List click Add and type the following URL into the location textbox
http://www.compadre.org
followed by clicking Add again, then the Continue button in the warning dialog. Repeat this process for any other sites you want this security setting for.
