If you are trying to load a file which is not in the same directory as your Java class  you ve got to use the runtime directory structure rather than the one which appears at design time    To find out what the runtime directory structure is  check your  root project dir  target classes directory  This directory is accessible via the     URL   Based on user4284592 s answer  the following worked for me   ClassLoader cl   getClass   getClassLoader    File file   new File cl getResource    docs doc pdf   getFile       with the following directory structure    root dir  target classes docs doc pdf   Here s an explanation  so you don t just blindly copy and paste my code    java lang ClassLoader is an object that is responsible for loading classes  Every Class object contains a reference to the ClassLoader that defined it and can fetch it with getClassLoader   method  ClassLoader s getResource method finds the resource with the given name  A resource is some data that can be accessed by class code in a way that is independent of the location of the code

If you don t specify any path and put just the file  Just like you did   the default directory is always the one of your project  It s not inside the  src  folder  It s just inside the folder of your project

Well  there are many different ways to get a file in Java  but that s the general gist   Don t forget that you ll need to wrap that up inside a try    catch  Exception e    at the very least  because File is part of java io which means it must have try-catch block   Not to step on Ericson s question  but if you are using actual packages  you ll have issues with locations of files  unless you explicitly use it s location  Relative pathing gets messed up with Packages   ie   src      main java     x txt   In this example  using File f   new File  x txt    inside of main java will throw a file-not-found exception   However  using File f   new File  src x txt    will work   Hope that helps

This sounds like the file is embedded within your application   You should be using getClass   getResource   path to your resource txt    which returns an URL or getClass   getResourceAsStream   path to your resource txt     If it s not an embedded resource  then you need to know the relative path from your application s execution context to where your file exists

Just did a quick google search and found that  System getProperty  user dir      returns the current working directory as String  So to get a File out of this  just use  File projectDir   new File System getProperty  user dir
