Write to ~/Library/ApplicationSupport/* with java?

I'm writing an Application for Mac in Java that needs to store a few preference files. By default, they seem to be storing to the User folder, but I'd like to store the files in the Library/ApplicationSupport folder, but I can't seem to figure out how to do that.

I've tried File file = new File("/Library/ApplicationSupport/AppName"); then file.mkdir() but it keeps returning false. I've tried adding ~ to the front of /Library/, and that didn't work either.

I've also tried just writing the file to the desired directory on a FileOutputStream, but no luck there either. I'm open to other ways of storing my preference files, I just don't want them stored in an obtrusive way to the user.

Thanks!

Solution

  • You can't write to /Library/ApplicationSupport because your user would not have the permission.

    The plain Java io classes don't understand "~", so to write to ~/Library/ApplicationSupport, you need:

    System.getProperty("user.home") + "/Library/ApplicationSupport"
