Trying to load a properties file from a Servlet and I'm getting null pointer excepion.  I can't figure out

1.  The code

// servet stuff...
Properties myProps = new Properties();
myProps.load(getClass().getResourceAsStream("conf/build.properties");  // << -- thrown from here **
String foo = (String) myProps.getProperty("foo);

2. On my appserver the properties file lives here.
 
$APPDIR/WEB-INF/classes/conf/build.properties

3.  Exception

java.lang.NullPointerException

        at java.util.Properties.load(Properties.java:293)
