Sorry System.getenv("windir")
looks like you need to upgrade java:

I mean: String fileName = System.getProperty ( "windir" ) ;

BTW that is still Windows-specific code. Move the "windir" to a properties-file and read from there.

Doesn't work on Java 1.4. You can Runtime.exec "cmd.exe /C echo %WINDIR%" on any version though

from the command prompt if you run as specified below. it works, but i am not sure how far it is useful for you.
java -Dwindir=%windir% Test
The method i mentioned is more tiresome than that, but less vulnerable. Let me know if you need to run on <= Win98

> java -Dwindir=%windir% Test

that is what you should be doing. You can then access the property uising

String windir = System.getProperty("windir");
