As previously communicated, Oracle announced the end-of-life of Java SE 8 (Standard Edition). Free public updates for commercial users are no longer available. Customers accessing Niagara with the Java Applet/Web Start are impacted by this change. Those who have upgraded to full HTML5 versions for your browser front-end will not be affected. For customers who use the Java VM and Java Web Start for their legacy systems, Tridium has developed a suitable alternative, the Niagara Web Launcher.


The Niagara Web Launcher is now available for download. You can download the Niagara Web Launcher using the following links. 


Niagara Web Launcher support is included with the following builds:

  • 4.4U3 - Included in (4.4.94.14). Release notes found here
