NetScaler Java Applet could not be loaded

21 Oct

So out of the blue after upgrading to a newer JRE our NetScaler Admin GUI stopped functioning, resulting in a nice JRE error:

javaapplet

Java Applet could not be loaded and then some possible reasons that don’t add up. This is another frustrating issue in the NetScaler Java GUI which isn’t working in general. I hope Citrix speeds up there HTTP console development. Anyway you can fix this (or at least work around it) disabling the Java Deployment Cache.

javaapplet2

Navigate to the control panel > programs > java > click settings in the temp internet location and uncheck keep temporary files. Alternatively you can do so by modifying the following regkey:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\AppDataLow\Software\JavaSoft\DeploymentProperties]
"deployment.cache.enabled"="false"
