Debugging getResource*
<p>How do you debug <a href="http://java.sun.com/javase/6/docs/api/java/lang/ClassLoader.html#getResource(java.lang.String)">getResource</a>-style methods that are failing, returning null?</p>

<p>I am sure the file it's looking for is there, but it's returning NULL. How do I know what it is looking for to try to spot any mismatch?</p>
