Filewriter-Printwriter not working with jar on linux

Question

I have this pieace of code:

    Calendar ca=Calendar.getInstance();
    FileWriter fw = new FileWriter("Locations_Elapsed time iterations.txt", true);
    PrintWriter pw = new PrintWriter(fw);              
    ca.setTime(new Date());                      
    a++;
    pw.write("user " + a + " " + ca.get(Calendar.MILLISECOND));
    pw.println();
    pw.close();

It works fine when I run it with netbeans (ofcourse). I want to execute it on a server away from my machine which works with Linux, so I make a jar file to do this.

The problem is that it is not writing anything. Any ideas?

Thanks!

Looks like there is a space in the file name you are trying to write to. Remove that and try again to see if it works — Vishal, May 28 '16 at 14:40
You haven't told us anything about how you're creating the jar file or how you're trying to execute it. Are you sure your code is running *at all*? Are you able to get other code (e.g. writing to the console) to run? — Jon Skeet, May 28 '16 at 14:41
And when you say nothing is being written, does it create the file? — Vishal, May 28 '16 at 14:42
@VishalKamat Thank you very much Vishal! It works indeed. Cheers :) — Iraklis, May 28 '16 at 14:46

I can't comment yet: can you give a little more detail about what happens when you launch the jar? How do you launch it? Where is the file you are calling stored?
At first glance I would think that you don't have a exception handling and thus you cannot see that the file hasn't been found or something on the like.
By the way, I suggest you (for testing purposes) to use Files.write

It might be that the user who is running the program does not have write permission in the directory in which the file Locations_Elapsed time iterations.txt is to be created.
