Auto-locating .jar

Question

I'm writing a program that has a JFileChooser.

I want default location opened in it to be the folder in which (once the program is created) programs (runnable) .jar file is residing.

Is there a simple way to locate the program inside a file system, or do I have to do it manually?

Also, if there is a simple way, what will be default location while my program is still just a project (not jar)?

try to use a xml/properties file that will hold the default location and load it in the filechooser during its initialisation — Jayant Varshney, Sep 11 '12 at 22:30

To find the executing location:

public static void main(String[] args) {
  new Test();
}

public Test() {
  JFileChooser jfc = new JFileChooser();
  File loc = new File(getClass().getProtectionDomain().getCodeSource().getLocation().getPath());
  jfc.setCurrentDirectory(loc);
  jfc.showOpenDialog(null);
}

When you're in the project, the directory will be where your class files are located. For example, project_dir/bin/.
