     Here it is.  If you change the package name, you will also
need to change the forName() call:

	// Foo.java:
	package esosman.misc;
	public class Foo {
	   public static void main(String[] unused)
	         throws ClassNotFoundException {
	      System.out.println("Calling forName() ...");
	      Class inner = Class.forName("esosman.misc.Outer$Inner");
	      System.out.println("Got class: " + inner);
	      System.out.println("Calling getEnclosingClass() ...");
	      Class outer = inner.getEnclosingClass();
	      System.out.println("Got class: " + outer);
	   }
	}

	// Outer.java:
	package esosman.misc;
	public class Outer {
	   static {
	      System.out.println("Initializing Outer");
	   }

	   static class Inner {
	      static {
	         System.out.println("Initializing Inner");
	      }
	   }
	}
