Re: [OS-webwork] hibernate/webwork2 best practices

[Matthew E . Porter]

I have looked at Spring and even had a chance to write some code using 
it.  However, I am not yet at a decision on it.

As previously mentioned, there is some work to do in order to plug in 
Spring's IoC.  We would lose some of the beauty of Actions having their 
components set without XML metadata.  Also, for those people using the 
Hibernate Open Session in View pattern.  See the mailing list 
discussion on why Spring is really suited for this and why that may be 
a good thing - 
http://sourceforge.net/mailarchive/message.php?msg_id=5769262 .

Speaking of Spring... has anyone looked at combining Spring's
Hibernate support with WW2? I'm currently doing this with WW1,
haven't had a chance to switch to WW2 yet. But there seem to be
some similarities to the components that Pat mentioned:
- HPM is analogous to Spring's HibernateTemplate
- HibernateConfiguration is analogous to Spring's
LocalSessionFactoryBean, which can be defined as a singleton in
the Spring container, achieving the same effect as scoping it at
the application level in WW2.
- PersistenceAware is analogous to a "setHibernateTemplate"
method that the Spring container would use
Note that the Spring container isn't necessary for any of this,
it sounds like you could easily use HibernateTemplate and the
LocalSessionFactoryBean in WW2. Spring's Hibernate support is
very good, I'm just wondering if anyone's tried integrating it
with WW2, or could that be part of Conductor?

+1 to that... The code from the book looked good... You guys
interested
in contributing it (or at least the infrastructure bits)?

Patrick:
   According to Wiley's website, the books is due in
November.  When
will this code be available?  The code I sent Jason has
some similar
interfaces but I would prefer to "standardize" on one as
it
would seem
weird that Conductor is not based upon the same code (and
practices) as
the first book talking about integrating these.

Glad you like it! Spread the word :)

I've used Hibernate + WebWork2 in a couple projects, and
I
always used
the
design that spawned from our (Mike/Joe/Ara/Mine) upcoming
book that
involves
writing Yet Another PetStore. Basically, we used the IoC
support
offered by
XWork and the following:
* PersistenceManager interface
* HibernatePersistenceManager class
* PersistenceAware interface
* HibernateConfiguration
The HPM class was scoped at _request_ scope in
components.xml and
depended
on another component, HibernateConfiguration, that is
scoped at
_application_ level so that we can keep a single
SessionFactory around.
Hope that helps.
