Question

I have a class that loads its properties file using class.getResourceAsStream(props.properties). The properties file is in the same package as the class itself, yet it is now returning null rather than the object. I am frazzled because this works fine on an original computer, yet fails on a different computer. I copied the entire directory structure over from the old to the to new. I’m using Netbeans 7.2.1 on both computers. I’m sure its got to be a classpath setting or SOMETHING but I cant find any differences between the two environments whatsoever. Here’s sample code:

package Cab;
import java.util.*;
import java.lang.reflect.*;
import java.io.*;

public class CabTest{

    public static void main(String[] args)
    {
        Properties  l_Prop = new Properties();
        InputStream l_IS;
        try
        {
           l_IS = CabTest.class.getResourceAsStream("props.properties");
           l_Prop.load(l_IS);
        }
        catch(IOException l_Exc)
        {
            System.out.println(l_Exc);
        }
    }
}

Answer 1

This says that if the .class file is in package “foo.bar.baz.props.properties”, then that’s the path you ought to give to the classloader:

l_IS = this.getClass().getResourceAsStream("foo/bar/baz/props.properties");

Your way will work only if it’s at the root of the CLASSPATH.
