Java 7 Update 25 may cause I/A Series G3 Niagara applet to fail.

Issue

 If JAVA 7 update 25 is installed, web browser users who login with a Workbench profile (which uses JAVA applets) are affected. The web applet is prevented from being started, and the browser appears to stop loading the Niagara user interface.

Follow the instructions contained in TPA-IA-13-0007.02 for the version installed. Remember to clear cache on the client workstation after updating!

Alternative workarounds are:

  • Edit user account to use HX profile. This does not use JAVA applets so does not require JAVA plugin. (Mobile profile in AX 3.7 should not be affected either).
  • Downgrade JAVA plug-in back to JAVA 7 update 21. This will require accessing Oracle JAVA archive and creating a free Oracle login to access the installer
