In addition, one of the biggest advantages of using spring is the testability. You can test all your queries and other db relatad stuff "without" starting the server and running the application. This really brings extra time during production.

We use JSF/Tomahawk + Hibernate + Squid as a front end cache. We moved from
Sun's Creator/Rowset/JDBC approach due to an increasing level of complexity
rowsets required for designing even moderately complex pages. Personally, I
think an object data model provided by a persistence layer like Hibernate
fits JSF much better than a rowset approach to managing data. The amount of
reusable code we use has increased, we can be more agile in our approach to
design because small changes in the database has very limited effects
throughout the rest of the code, and the ability to make de-couple data
objects and use tomahawks savestate tag and then re-couple the objects to
the database later makes a very compelling argument as it greatly simplifies
many of the CRUD operations our app requires.
When we moved to Hibernate, none of us had used it but it was well worth the
effort. However, we found that we had to redesign most of the app --
actually a complete recode -- when moving from rowsets to Hibernate. This
was a good lesson in learning the impact of early choices during systems
design. Recommendation, take the time now to learn an object model such as
Hibernate because it will cut down on future dev costs and you will end up
with less code, more flexibility and a more portable app. Last but not
least, we use MySQL 5 as our backend but one of our customers wants to host
on MS Sql Server -- it took us about 2 hours to prove that we could port to
Sql Server (changed only 4 queries which used date calculations) as
Hibernate did the rest.

Hi,
I use JSF, but I do not use Spring at all in my applications. I use JDO to
persist my objects to the database, but can use any database technology -
including writing the JDBC code yourself, instead of Hibernate.
The good thing about Java is that you have a wide choice as to what
technologies to use. Spring, JPox (my choice of JDO technology), Hibernate,
Ibatis and many, many more frameworks are available - if you want to use
them. If you are learning one technology e.g. JSF, you may find it easier
to not use any other frameworks until you are confident in that technology.
Then you could look at adding another framework, e.g. JDO to store/retrieve
data from the database. This way you are only looking at one new technology
at a time. If you tried to start from scratch and learn 3 or 4 technologies
at once you are bound to find yourself very confused.
In short JSF does not require you to use any other technologies.
HTH,
Fintan

Currently I'm using JSF myfaces, do I need to use Spring + Hibernate?
Find them quite complex to use...
