Hey, these are just bits and bytes on the disk, so nothing is impossible ;) Sure, given enough time and resources you could write a converter; all I'm saying is that it would take a lot of tedious and error-prone coding, so for all practical reasons it's better to dump/inject and re-fetch. Unless your segment data is so precious that you are willing to bear the price of writing a converter. -- Best regards, Andrzej Bialecki <>< ___. ___ ___ ___ _ _ __________________________________ [__ || __|__/|__||\/| Information Retrieval, Semantic Web ___|||__|| \| || | Embedded Unix, System Integration http://www.sigram.com Contact: info at sigram dot com ------------------------------------------------------------------------- Using Tomcat but need to do more?
