moving on to Hibernate with S2...
Now I'm trying to configure Hibernate with S2, which many others have
done. I was trying to follow the example in WebWork in Action, but
things have obviously changed since then.
To be clear, the problem is to create a SessionFactory once in such a
way that all my actions can easily have access to it. The approach in
WWiA uses IoC. As far as I know, it would work in S2 but would need
many modifications because package names have changed. And perhaps
other mods would be needed?
I'm not sure if the best approach is:
a) Use the strategy in WWiA, but change the import statements to match
the current jars (and perhaps make other changes to match S2)
or
b) Something else.
Perhaps someone could point me to a complete solution?

If you like RoR (and I do) you might like some of the "magic" that
Struts 2 and Spring can provide. It isn't quite perfect yet (at least
not the Struts 2 part), but I'm pretty happy with it. By "magic" I
mean convention based configuration, which cuts down on the number of
places you have to enter the same data.
With a default Struts 2 + Spring IOC setup, adding a new Action means :
1. Create an Action class
2. Create a view file (JSP in my case)
3. Describe the Action class and view in the struts configuration
file (struts.xml)
4. Describe the Action class in the Spring IOC configuration file
(applicationContext.xml)
5. "Wire" the dependencies needed by the Action class in the Spring
IOC configuration file (applicationContext.xml)
This seems like a lot of work, especially compared with RoR. My
solution has been to use the following pieces of "Magic":
1. Struts 2 "Zero-Configuration"
2. Spring IOC "autowire by-name"
3. Struts 2 Spring Integration
This cuts the above steps down to:
1. Create the Action class.
2. Create the View file
3. Annotate the Action class.
4. Add IOC properties to the action class
This only saves 1 step, but it cuts the number of configuration files
edited from two to zero. In fact, the only files that need to be
edited are your Action and your View, which is just what RoR requires.
The downside, is the mess of Annotations that this approach requires
on the Action class. There is also a "codebehind" plugin for Struts
2 that I have yet to try out, but might cut down on the required
Annotations.
The missing piece here is the Model component. Hibernate offers one
solution, and by using Annotations instead of mapping files, you can
get close to the simplicity of Active Record, though not in terms of
setup. My preferred solution, as of late, is to implement a Data
Access Layer. This is more complicated, and more work to setup and
maintain than Active Record, and certainly requires more typing than
Hibernate alone. However, I find that more often than not, the
database can prove to be a performance sticking point. By having a
clear DAO layer I can tweak resource hogging auto-generated queries
without having to touch domain logic, which is what I found myself
doing when relying on Hibernate alone.
For example, if I have a survey building tool with an administrative
front end, and I have an Action defined to assign questions for a new
survey, the action might receive a surveyId and a list of questionIds.
With Hibernate alone, I would be tempted to write something like the
following in my Action class:
Survey selectedSurvey = new Survey(surveyId);
hibernateSession.load(selectedSurvey);
selectedSurvey.setQuestions(null);
for (long questionId : questionIds) {
Question q = new Question(questionId);
hibernateSession.load(q);
selectedSurvey.addQuestion(q);
}
hibernateSession.update(selectedSurvey);
Now, that's a terrible example of database usage, but it sure was easy
to write, and its rather readable, even with no comments.
Now, with a DAO layer defined, I might write something like this in my
Action class:
surveyDAO.setAssignedQuestions(surveyId, questionIds);
In the definition of the surveyDAO, I might use the same code that I
previously put in my Action class, and it might never prove to be a
problem even with all the excessive database. However, if it did
prove to be a problem, I would know exactly where to address it, and I
could be assured that my database performance tuning would be
restricted to its own layer, and would not make my action any less
readable.

Personally, I do *NOT* like to use Spring, because every time I touch it
everything breaks. I think that a better solution is to use a
ServiceLocator to provide the Hibernate SessionFactory. I did this in S1,
and it worked very easily, and didn't break anything. ServiceLocator is
described in the "Core J2EE Patterns" book very nicely (available on-line at
Sun). In my opinion the rush to IOC and DependencyInjection is more of a
fad/hype than a real benefit. ServiceLocator is easier, and makes your app
more portable, because you don't have to implement the IOC service before
you can get your code to work in the new framework.
All this, of course, is IMHO, and I know I'm probably a minority here.

I'd say getting everything set up is what hurts, after that, it is very
nice. I'm running Struts 2 with JPA and Toplink and I'm quite pleased.

The funny thing is that I've spend the past few months working with
RoR. I like it, but I finally have some time to investigate the Java
world. I have this nagging concern about RoR performance.
One thing I hope to learn soon is, once over the pain of initial
configuration with Java based frameworks, how hard is it to add another
class, view, etc.

That's what we're using as well.
Plus using EJB3/Annotations (over Hibernate3) for persistence.
Works well. No show stoppers thus far.
If don't expect your web app to be too complex, I'd recommend a hard
look at Ruby on Rails.
The whole S2, Spring, Hibernate thing is very powerful. However, it
is getting too
bulky w/configuration and dependencies for less complex projects.

Spring has several components, but the one I use (and the one I think
is the most popular) is the Inversion of Control (IOC) framework.
Struts 2 (when it was Web Work) had some IOC support, but it wasn't as
full featured as what Spring offers.
Spring also has an MVC, which is a direct competitor to Struts 2. I
personally don't like Spring MVC, and would much rather use Struts 2.

Re: moving on to Hibernate with S2...
Posted by Rick Schumeyer <rs...@ieee.org>.
Let me ask you a question that I've never really received a good answer
to. Keep in mind that my knowledge of Java web programming is some S1,
and just starting with S2. I have never really looked at Spring.
I understand that S2 and Spring somehow work together. What I don't
understand is: why would I want to use both of them? If Spring is so
great, why don't I just buy a copy of Spring in Action and forget about
S2?
I guess I'm looking for answer to: what problem does Spring solve that
S2 does not? And vice-versa.

Have you tried using Spring?. It plays nicely with Struts and hibernate,
plus there are some examples around I think.
