The same document parsed with an old version of POI (containing the serializer, before it was integrated in cocoon).

Oliver [mailto:[EMAIL PROTECTED]] Envoy� : mercredi 31 juillet 2002 14:09 � : POI Users List Objet : Re: HSSFSerializer / Null Pointer exception Does the same document parse when using the HSSFSerializer inside of cocoon? This may be a missing element. The Serializer doesn't have great error reporting.
