Acho que o problema é o método ORB.init(), sem parâmetros, que você
está chamando. Veja uma parte da descrição desse método na classe
org.omg.CORBA.ORB:

"This no-argument version of the method <code>init</code> is used primarily
as a factory for <code>TypeCode</code> objects, which are used by
<code>Helper</code> classes to implement the method <code>type</code>.
It is also used to create <code>Any</code> objects that are used to
describe <code>union</code> labels (as part of creating a <code>
TypeCode</code> object for a <code>union</code>).
...
If an ORB is created using this method from an applet,
a system exception will be thrown if
methods other than those for
creating <code>TypeCode</code> objects are invoked."

Agora veja a implementação do método
com.sun.corba.se.impl.orb.ORBSingleton.string_to_object() que seu
invoker chama:

   public org.omg.CORBA.Object string_to_object(String s) {
	throw new SecurityException("ORBSingleton: access denied");
   }

Acho que a mensagem poderia ser um pouco melhor que "access denied"
:-). A instância de ORB retornada por ORB.init(), sem parâmetros,
serve apenas para criar TypeCodes e Anys. Para obter uma instância de
ORB "completa", execute:

ORB.init((String[]) null, null);

Bom trabalho!
