Honestly, I think the time you spend investing in Hibernate and Spring
(though you probably don't need spring yet) seems high up front, but you
quickly save it in overhead of writing JDBC style code which is slow
compared with Hibernate style code which goes very fast once you've got your
initial set up. You don't have to sit there writing
statement.setInt(1,MyObject.getId()); for all 20 fields in your table every
time you want to populate a statement. You just plug in your Hibernate
entity to a stripes form connected to an Action bean, and just call
MyObjectDao.save(MyObject); MyObjectDao.commit() and you're done. I've
written over 6000 lines of working code in the last two weeks and have a
website project well on it's way to functional with a dozen ActionBeans so
far, 25 or so Entities, and their DAOs, and a bunch of JSPs. At the start
of this project I had never used Hibernate at all, and had a basic
understanding of Spring. The Daoud books is an invaluable resource, and
doesn't take long to get through and introduces you to hooking Stripes up to
hibernate and spring, both of which are trivial.
