This is something that's been debated on the list in the past. The general consensus was:
For manipulating data in the database, nothing beats pl/sql. It is well suited for this purpose. For everything else, java could beat it. I am sure fellow list members will post links describing studies. I remember seeing these last year. Stefan, have you tried running your own test? There's a sure fire way to convince yourself. Even a small test (no fancy code) would suffice. Wish I had more time to play... Lisa Koivu Oracle Database Monkey Mama Fairfield Resorts, Inc. 5259 Coconut Creek Parkway Ft.
