Detecting the Microsoft JVM Build

[Ron Baker]

I am writing an applet that will detect the Microsoft JVM Build. i have the following code (simplified):

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

but i get:
test.java:6: package com.ms.util does not exist
build=com.ms.util.SystemVersionManager.getVMVersion().getProperty
^
1 error

i am using the j2sdk 1.4.2.

what am i missing?!

Any help would be greatly appreciated.

Because you're using a class that only exists in the Microsoft VM, you need to first realize that the applet will fail to start on a non-Microsoft VM. If you're OK with that, then what you need to do is to add the JAR or zip file containing those Microsoft classes to your classpath when you compile this code; i.e.,

javac -cp .;c:\wherever\whatever.zip test.java
