you could inspect the JVM system properties. specifically properties
like java.home. have a look at the Properties instance returned by
System.getProperties() on your various deployment platforms and see if
this at least can be used as a hint.

It is %windir%

It is %windir%

And in JRE 1.5 retrievable with:
System.getenv("windir");

In older JRE versions getenv(String) is deprecated and, when run, throws
an error, like:
java.lang.Error: getenv no longer supported, use properties and -D
instead: windir

System.getenv("windir");

on older can you try ....run("echo %windir%")....

I forget the syntax exactly.

Hi all! I have a question about Java and Windows systems...

Why Windows specifically?

..It's possible to
obtain the exact path of windows installation folder using Java functions?

Why do you feel you need to know?

A lot of people misunderstand things like where to put their
own Java classes, or resource files like images and web pages
and such.

In any case, you can get it this way..
<sscce>
public class JavaLocation {
public static void main(String[] args) {
Object o = new Object();
java.net.URL url =
o.getClass().getResource("/java/lang/Object.class");
// you can use the String methods to extract the path
System.out.println( url.toString() );
}
}
</sscce>

Note that yhis will throws security exceptions in unsigned
applets, unless the user is running IE and using the MSVM.
