SUMMARY

Java applets are blocked despite being added to the exception list due to security settings in Java version 8 update 40. Users on both macOS and Windows have reported persistent issues accessing applets, even after rebooting and modifying exception lists. The recommended approach includes adding the entire domain or specific subdirectories to the exception list to potentially resolve the issue. Users should consult the Java Control Panel for further configuration options.

PREREQUISITES
  • Understanding of Java applet security settings
  • Familiarity with Java version 8 update 40
  • Knowledge of browser exception lists in Safari and Google Chrome
  • Basic navigation of the Java Control Panel on macOS and Windows
NEXT STEPS
  • Review Java Control Panel security settings for applet permissions
  • Learn how to add multiple URLs to the Java exception list
  • Investigate compatibility issues between Java applets and modern browsers
  • Explore alternatives to Java applets for web applications
USEFUL FOR

Web developers, IT support staff, and users attempting to access legacy Java applets on modern systems.

I am trying to view some possibly old java applets on this site:
http://aleph0.clarku.edu/~djoyce/java/elements/bookI/bookI.html

I keep getting promoted that they are blocked. I have tried to add this site to the exception list but it has not changed anything. I closed all pages, and have since shut down and rebooted my computer and still not change. Any ideas?

I have java version 8 update 40 - the most up today java. I am running a mac. Have tried in both safari and google chrome with no luck

If it does not work add this to exception list: http://aleph0.clarku.edu/ [if it doesn't work add every page as a website Example: http://aleph0.clarku.edu/~djoyce/java/elements/
Those idiots did it
