If your file would be HUGE, I guess that your data comes from a database?
If so, then you could use the sql taglib to get only the information you
from the DB on the fly. A more sophisticated solution could be using Cocoon
with Castor (see .
BTW, I think that Castor looks good but I didnt' manage to get it up and
