java - Filewriter-Printwriter not working with jar on linux -

-

i have 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 " + + " " + ca.get(calendar.millisecond));     pw.println();     pw.close();

it works fine when run netbeans (ofcourse). want execute on server away machine works linux, make jar file this.

the problem is not writing anything. ideas?

thanks!

i can't comment yet: can give little more detail happens when launch jar? how launch it? file calling stored?
@ first glance think don't have exception handling , cannot see file hasn't been found or on like.
way, suggest (for testing purposes) use files.write
