Question

I am sure it’s a basic question , I just can’t figure it out
I am trying to load bunch of images located in images subfolder of my project

here is my code

package com.ieml.swt.diploma;

import java.io.InputStream;



public class loadTest
{


    public static void main(String[] args) 
    {

System.out.println(getResourceImage("marks.png"));
    }


    public static InputStream getResourceImage(String fileName) {

        return loadTest.class.getResourceAsStream("./images/" + fileName);
    }
}

I have a separe folders for src and class files
so .java file is located in src/com/ieml/swt/diploma folder
and .class file under bin/com/ieml/swt/diploma folder
files I’m trying to load here do existt in the “loadTest/images” subfolder loadTest is my project’s root directory
it justs print s null like it’s doesn’t load this file
am I missing something here ?

Answer 1

loadTest.class.getResourceAsStream("./images/" + fileName);

This will look for the images under bin/com/ieml/swt/diploma/images, i.e. relative to the .class file. If you leave out the dot in the beginning, it will look in bin/images.

But whatever you do, Class.getResourceAsStream() is for loading resources from the classpath, i.e. inside the bin folder. There is no way to access anything outside, and it wouldn’t make much sense anyway, since it’s designed to work for JAR files as well. Usually, you actually put the resources in the src folder and copy them to bin during the build (eclipse will do this automatically).
