Re: java.policy ?

Michael,

When you changed the name, did you use forward slashes (recommended) or at
least double back slashes?  The back slash is an escape character.  So many
times when you specify file names on windows using the back slash, you have
problems.  I normally recommend the use of forward slashes.

All this being said, the "java.home" property is a standard Java system
property which holds the installation directory for the current JVM.  Java
should figure this out on its own even under Windows.  So, you should be able
to leave "${java.home}" and have it appropriately populated.  You can print out
its contents on your Windows System with the following:

    System.out.println("Java home: "+System.getProperty("java.home");
