Thanks Peter for the insight as to using this.getClass().getClassLoader().findResource(PROPS_FILE). I found one other tidbit that might help someone if they are using the relative path. In the junit ant task, they can specify the directory where they want the jvm to execute from. You do this specifying fork='yes' and dir=. The dir is where the jvm will execute from.
