java - linking text resources in eclipse

I want to parse a text file called "hops.txt" which is located in a folder called "res"
inside the main project's folder.

When running the following code: 

package parsing;

import java.io.InputStream;

public class ParseTest {
public static void main(String[] args) {
    ParseTest pt = new ParseTest();
    pt.foo();
}
public void foo()
{
    InputStream is= this.getClass().getClassLoader().getResourceAsStream("hops.txt");
    System.out.println(is);
    is= this.getClass().getResourceAsStream("hops.txt");
    System.out.println(is);
}
}

I recieve the following output:
null
null

What am I doing wrong? Thanks!

Solved the problem by deleting the folder res and putting all the files under a package with the name "res" under the "src" folder.
After that using the code: 

InputStream is= this.getClass().getResourceAsStream("/res/hops.txt");

and it worked.

The path parameter of getResourceAsStream is assumed to be relative to your project root. Because this text file is in a folder within your project, you must include the folder name in the resource path.

this.getClass().getResourceAsStream("/res/hops.txt");
