Method Detail

isApplication

This is kind of a hack. The java runtime name property cannot be accessed from an applet environment due to security restrictions. A call for this property causes:

java.security.AccessControlException: access denied (java.util.PropertyPermission java.runtime.name read)

to be thrown. This approach may fail if the user has monkeyed with their java.policy file and the security permissions therein.
