I need to write "indice_corrente.txt" file. The structure is:

Home
  src
    Grafica
       FinestraPrincipale.java
       indice_corrente.txt

I need to write hello in "indice_corrente.txt" so I use this code to get Resources:

    String path=this.getClass().getResource("/Grafica/indice_corrente.txt").getPath();

PrintWriter pw=new PrintWriter(path);

But the string path is null because the getResource is null. Anyone can help me to resolve this?

write to a file IN a jar? why would you do that? – Stultuske May 09 '17 at 16:36
Try : `Home/ressources/Grafica/indice_corrente.txt` – Zorglube May 09 '17 at 16:36

you can't write to a file inside a jar. you need to build and repack a new jar with the changed file. – Raphael May 09 '17 at 16:52
