your applet tries to access some (maybe critical) system resource that an
applet isn't allowed to access per default. you need to sign your applet to
get access to those resources (refer to
http://developer.java.sun.com/developer/technicalArticles/Security/Signed/in
dex.html for further information).
Maybe the source of your applet might also be helpful...
