Need help with PrintWriter!

Hello, my first post. It doesn't write anything to the file.
Sry for the variables, it's in Swedish:^):

Code:

---

              PrintWriter skrivfil = new PrintWriter(new BufferedWriter(new FileWriter("LagerV.txt")));
        enrad = readfil.nextLine();
        Artikel a2 = new Artikel(enrad);

        skrivfil.println(a2.geteanKod() + a2.getvaruNamn() + a2.getlagerVr());

---

Now when it's running I get this problem.

Code:

---

Exception in thread "main" java.util.NoSuchElementException: No line found
        at java.util.Scanner.nextLine(Scanner.java:1516)
        at lagerV.main(lagerV.java:27)

---

I've tried if it prints out anything in the file only by not giving the variables no values, I get null.

Code:

---

PrintWriter skrivfil = new PrintWriter(new BufferedWriter(new FileWriter("LagerV.txt")));

skrivfil.println(a2.geteanKod() + a2.getvaruNamn() + a2.getlagerVr())

Tells you that the problem is not with the PrintWriter but with the Scanner object, readfil. It is trying to read in a line, but no line exists.

Thx! I got it working! But it's strange, I only manage with success run it on Mac! It doesn't work on Windows? (Windows trash! ;D) I can compile it and run it, but I get this error...
What is wrong? My constructor? Just tell me if you want to see the code.

Code:
