The code-snippet below illustrates how to get the version information of the Microsoft Virtual Machine for java from your Java applet or application:

Create a Java Project and include the following class to it:

   class test
   {
      public static void main(String[] args)
      {
       String build;
       build=com.ms.util.SystemVersionManager.getVMVersion().getProperty
            ("BuildIncrement");
       System.out.println("Using build "+build);
      }
   }
