Hello,

could someone pleas tell me, how I find out from inside the program, in
what path it is installed?

The property user.dir returns only the working directory but this is not
necessary the path to the Application.

System.getenv(String) is deprecated.

Thank you for any answers in advance.

Try:
System.getProperty("java.home");
(then you could append bin/java -or- bin\java.exe -or- bin\javaw.exe)

Regards

There are several different meanings to that question. One of them is
where did a given class file come from. See

Here a stand-alone example:


import java.net.URL;

public class App {
public static void main(String[] args) {
App app = new App();
System.out.println(
(app.getClass().getResource("App.class")).getPath( )
);
}
}

Of course you could replace "App.class" by

app.getClass().getName() + ".class"

This code doesn't work. Or rather, it only works if your application is
composed of loose class files, but obviously isn't (or, at least,
hopefully isn't!) the case when you deploy the application.

I wrote a very complete and detailed answer to this question some time
ago. It's temporarily available in Word format at the following rather
ugly URL:

No, System.getenv(String) is not deprecated.
