Why aren't you using some kind of ORM? At least use a light-weight library for translating data base entities into objects. <http://commons.apache.org/dbutils/> Also JPA will do some kinds of automatic instantiation for you: <http://openjpa.apache.org/builds/1.0.4/apache-openjpa-1.0.4/docs/manual/jpa_ov erview_mapping_inher.html> I didn't check to see if those are the most recent docs (I don't use this sort of feature). Google for "JPA table inheritance" and check through the results carefully. > Class is a simple version containg only the important parts. Honestly, while we all appreciate the attempt, you example is far from complete. We can guess at a few things, but you should think much more carefully at what the real problem is and design something to illustrate it. --- BBBS/Li6 v4.10 Dada-1 * Origin: Prism bbs (1:261/38) --- Synchronet 3.16a-Win32 NewsLink 1.98 Time Warp of the Future BBS - telnet://time.synchro.net:24
