Is there any way to add resources to a class or package in java? For example, if I use JFileChooserto give user an option to choose any image file. Let's say user has already selected a file from his desktop(or any other directory). I know that I can get it's location by calling method getSelectedFile().toString() and it will return me directory of file in String format.

So now my desired operation is that I want to add this file into the resources of class. I want to add because I want to retrieve this image/file later by calling this.class.getResource() method.

Please guide me, Thanks.

Why are you retrieving user-provided files (which are guaranteed NOT to be part of your class resources) in such a way? Why aren't you using the regular filesystem IO API? –  Tom G Aug 5 '13 at 20:44
    
As @TomG said why don't you store selected file into some other directory and read it from there with normal java IO? –  Piro Aug 6 '13 at 10:04

In the following link is a rather ugly hack that adds to the SystemClassLoader at runtime. Adding files to java classpath at runtime

Is there not any simple way? My requirement is just that I want to add a file into resources at run-time. For example:- String fileName = "C:/Users/Zulfiqar Junejo/Desktop/profile.jpg" Now is there any way to add the file represented by this dir to resources? –  Zulfiqar Junejo Aug 5 '13 at 18:08
    
You can only add folders or jar files to a class loader(which contains all resources). See Javadoc: docs.oracle.com/javase/7/docs/api/java/lang/… –  Khinsu Aug 5 '13 at 18:13
