Nope.
Nobody is saying you *can't* do it like you are
describing. And it'll work great, until you want to:
(a) Change how your objects are persisted (say,
switching to iBatis, or Spring-based JDBC, etc.)
(b) Test parts of your logic/app/flow without having
to use a real database (for instance, to simulate
failures, operate on arbitrary data, create
pathological use cases, etc.).
> So, no point in doing things OO ?
Depends. Is it non-OOP to separate concerns? The
representation of my data is not related to how it is
persisted. If how I store my data *does* undergo a
change it's like to be a very large infrastructural
headache.
I would rather change well-defined persistence
interface classes than modify all my POJOs where I
have an additional set of concerns in the code.
I'd argue that compositing objects (POJO, service
impl, whatever) is more OOP than tightly coupling two
(largely) unrelated concerns.

Nope.
You can do everything by hand: roll your own
persistence layer, do your own type conversion, write
HTML by hand, etc.

Is Struts the best choice for every project?
No. If you need to write a very simple application,
with a handful of pages, then you might consider a
"Model 1" solution that uses only server pages.
But, if you are writing a more complicated
application, with dozens of pages, that need to be
maintained over time, then Struts can help. For more
about whether Model 1 or MVC/Model 2 is right for you,
see Understanding JavaServer Pages Model 2

S2 goes a long way to lowering the entry barrier
(compared to S1) but I don't feel it's the best choice
for simple use cases, particularly if you're not
already familiar with Java's host of supporting
frameworks: there is a steep learning curve to writing
a full-stack Java web-app if you're starting from
ground zero.
Personally I don't recommend it unless you have a
decent non-technical reason ("My boss said I have to
use Java" or "This hot chick said she'd go out with me
if I used Struts 2" etc.) or a decent techical reason
("Everything else we have is in Java" or "I already
know everything about Spring and Hibernate; it would
be quicker" or "All we can deploy on is Tomcat" etc.)
