The OraFormsFaces' applet contains code which is trusted and also untrusted.

You have to open the Java Console from Control Panel (in the case of Windows) and change the security settings in order to make the display of the warning message go away.
To access the Java Control Panel goto, Start menu > Control Panel > Java Control Panel > Advanced > Security. See the Mixed code heading towards the bottom of the Java Control Panel.
You can tick any of the two "Enable - hiding warning..." options provided. In my case I picked: "Enable - hide warning and run with protections." I've included a screenshot of the Java Console Security options as it is displayed in Windows 7:
