You cannot get it by default. Here are all the systrem properties you have in java: http://java.sun.com/docs/books/tutorial/essential/system/properties.html

You will need to pass it using the -D argument: java -Dsystem.path=<path to system, folder>

Since JAVA 1.5 (or 5 as they call it now) you can get your environment variables
by:
        String value = System.getenv("key");  // E.g.:    .getenv("TMP");

It worked already in 1.3 but was blocked in 1.4 for some reason.

Well, then it's:

      String path = System.getenv("WINDIR");
      File system = new File(path + "\\system");  // System
      File system32 = new File(path + "\\system32");  // System32

What more do you want?

i'm using jdk1.4, when i used this code, an error occurred.

java.lang.Error: getenv no longer supported, use properties and -D instead: WINDIR
at java.lang.System.getenv(System.java:691)

but in used,
System.getProperty("WINDIR-D")  
or
System.getProperty("WINDIR")

it returns null.

You did not read my comments above: in 1.4 getenv was blocked.

WINDIR is a MSWindows dependent property,
 JAVA has only platform independent properties in System.getProperty()

What you can do is assume that System\ and System32\ always
reside in C:\Windows or C\Winnt\

So, you could say:

String path:
      if(!new File("C:/Windows/System32").exists) //    Yes, use /
      {
             if(!new File("C:/Winnt/System32").exists)
             {
                    System.out.println("CAN'T FIND MY WAY!");
             }
      }
// here you'll have the correct name of system32's parent directory in 'path'.
// b.t.w. I've seen systems at a large company where everything was installed on D:
// so, maybe you should include that too ...

qirionis is right - you should start your app using:
java -DWINDIR=%WINDIR% ...

then you will be able to take it using:
System.getProperty("WINDIR");

Clumsy! you have to specify that for every system that you will run on!

Hi Naeemg,

You can get the "java.library.path" property, and parse each path element to find something like <drive>:\winnt\system or <drive>:\windows\system

sciuriware,

the -DWINDIR option might be clumsy but safe.. If later on he'll want to use the /sbin or something, he's capable of doing that. And when he wraps the application in an EXE, he can make it a default property.

You can't wrap it into an exe and this is not a JAVA solution at all.

But ofcourse you can, dear sciuriware!

http://www.ej-technologies.com/products/exe4j/overview.html

Maybe its my opinion alone, but I think a real Java solution is a solution which leaves the Code cross-platform, and the wrapper (whether its an EXE, shell script, batch, or even a service/daemon) platform-specific.
