reading a resource ends up null

Question

I have the following code

System.out.println("Path::: "+path);
InputStream resource = this.getClass().getResourceAsStream(path);

Now path is: src/resources/FF/1-Battle.mp3

This is my folder structure:

src 
 |- resources
 |    |- FF
 |    |   |- 1-Battle.mp3
 |- folder
 |    |- prog.java   <- this is the place where the code is run

The problem is that resource (The input stream) is ending up null

This needs to work from a jar file so i need it to be relative from the jar file root directoy not the hard disc directory, and hence i cannot create a File since inside a jar file the files are not classifiable under java.io.File

Answer 1

Why can't you just read it using FileInputStream ? Something like this:-

InputStream fileStream = new FileInputStream(new File(path));

and make sure, the path is a proper relative URL.

Answer 2

Did you try using a relative path to where the program is executed? Like '../../resources/FF/1-Battle.mp3"?

Answer 3

It looks like you are trying to read an mp3 file from within a jar file since the mp3 file is within your src folder. Try this:

    try {
        ClassLoader cl = this.getClass().getClassLoader();            
        InputStream resource = cl.getResource("resources/1-battle.mp3").openStream();
    }
    catch(Exception ug) {
        System.out.println("Failed to load mp3 from jar:" + ug.toString());
    }
