Hi,

at the moment im trying to retrieve the standard program path ("C:\Programme" or "C:\Program Files" or ... it�s language dependent) from Windows 2000 with my Java program (JDK 1.5).
Does somebody have an idea?

I had a look at java.lang.System, here i get the user.dir (working directory) by

       String s = "";
       Properties P = java.lang.System.getProperties();
       s = P.getProperty("user.dir");
       return s;

but this is not exactly what i want.

thanks

Oliver

Have you tried looking for an environment variable (or property) called 
"ProgramFiles" or "PROGRAMFILES" (depending on which sort of shell you 
start your program from)?

http://java.sun.com/j2se/1.5.0/docs/api/java/lang/System.html#getenv(java.lang.String)

On my Windows 2003 Server, the environment variable is "ProgramFiles"

Note that System.getenv() was deprecated from JDK 1.1 to JDK 1.4, 
resurfacing in JDK 1.5.

Hello,

ok, many thanks.

Ok, now i have one question still: i have another (similar) project in JDK 1.4. Is there another possibility in 1.4 to retrieve the ProgramFiles Dir?

regards

Oliver

Not without the use of JNI.

Or by the classic dodge of exec'ing a helper program to write out the 
values of environment variables:

   Process p = Runtime.getRuntim().exec("cmd /c echo '%PROGRAMFILES%'");
   // Read the output from p.getOutputStream()

Hello,

thank you both. I have one little remaining question: how can i read from the OutputStream? (toString() returns the address of the object, but where is the content?)

Whoops. I meant Process.getInputStream(), which contains the output of 
the process. Read from it like any other InputStream.

Once you get the InputStream class, you read it as you would any other
InputStream. I would recommend you place it in a BufferedStream type class
however (like BufferedReader).
