I'm wondering how writing *very* simple Java code (mostly classes with a 
handful of private data fields with getters and setters, and even this 
step can largely be automated using Hibernate), is worse than writing 
SQL code, forever tieing your presentation layer to the implementation 
of your storage layer.

I've been using Hibernate for about a month in a business application 
and have concluded what follows:

a) Hibernate is a great product, rock solid and very well documented
b) using Java Beans as the Model in MVC beats writing SQL DML statements 
hands down
c) using an object cache, connection and statement pooling, and 
fine-tuning your loading policies (eager vs. lazy) could give a big 
performance boost to any web application (and no, I haven't any 
benchmarks about this, it's just a gut feeling).

Only "problem" with Hibernate so far: it's LGPL. But you can always go 
with Jakarta OJB if you're picky about licenses.
