Java 7 Update 51 Blackboard Problems

Java 7 Update 51 has introduced additional security settings that block applications without an up to date “Permissions manifest attribute”. The multiple file upload as well as collaboration tools (virtual classroom and chat), Blackboard Collaborate Voice Authoring Tools, Blackboard Collaborate, and the Equation Editor will either not load or function properly. Blackboard is working on a solution for the problem.

If you have installed this version of Java on your personal machine, please follow the workaround steps below to access all features again within Blackboard.

Add Blackboard URLs to the site exceptions in Java. This will tell Java that Blackboard and its plugins are safe applications to load.

    • Windows/Mac – Open your system control panel or System Preferences and choose Java.
