While running icontrolsdk index.html I am getting IHTOC Applet error?

We've had some problems with the Java applet that the offline SDK uses. It ties into Java security changes that have been made over time with various browsers. I'd make sure that Java has access to the local file system to load the hierarchy xml file.

If you don't absolutely need an offline SDK, I'd recommend using the online API documentation in the DevCentral Wiki. It's up to date as of v11.4.1.
