Loading Java Applet Failed

We have an internal controller for our HVAC systems. Members of our maintenance dept can access the controller through a web portal. When we try to access the site, we get the following error:

load: class com.jci.metasys.ui.applet.MetasysApplet.class not found.

We are running the most up to date version of Java, but cannot access the page. Any ideas?

No one has seen this error at all? Could really use some help! Do you need more information?

I haven't seen this exact error, but I have dealt with these Metasys units in my own environment. From what I understand specific versions of the Metasys program require you to be using a specific version of the Java runtimes on the PC.

These are the versions that I know of and what Java Runtime is required.

For Metasys 2.1, JRE 1.5.0_04 is required.

For Metasys 2.0, JRE 1.3.1_15 is required.

For Metasys 1.1.2, 1.1.3, and 1.2, JRE 1.3.1_10 is required.

For Metasys 1.1, JRE 1.3.1 is required.

In otherwords in this case running the latest version isn't what you want.
