Error using IMAGE/IO in a Servlet

I'm trying to read a .tiff on the back end of my server. I do:

FileImageInputStream fis = new FileImageInputStream(new File(p_tifName));
Object o = ImageIO.getImageReadersByFormatName(
TIFFImageReader reader = (TIFFImageReader)o;

If I run this code in the Servlet via a main() it works fine. But when running in Dev Mode, I get the error:
java.lang.ClassCastException: cannot be cast to

I have the imageIO.jar on the class path. Everything seems happy, except in Dev mode. Does anyone have any ideas? I'm at a loss at how to get around an error saying a class can't be casted to itself.
