My Wicket + Hibernate project- Transaction solutions? Java EE w/
Wicket?
I'm just curious what everyone is using for transaction management. I have
been working with Wicket for a while now (and loving it) on a pet project
that also uses Hibernate and Guice.
I'm realizing now that I might need/want transactional support for a couple
parts of my app.
I don't have any experience with Spring or Java EE or EJB, but have been
avoiding Spring because of what I have read and seen online with so much
XML-coding. Is it possible to use spring transaction module by itself and
without too much XML? I'd really appreciate hearing what y'all are you guys
using for your transactional needs.
Also is it possible to run a Wicket-based project inside a JEE container
like Glassfish or JBoss AS directly to take advantage of EJB & JTA,
or would that require something like Seam + wicket-seam integration?
If anyone has recommendations on where to get started with transactions,
that would be great too.
Thanks!
J

If you're using Tomcat then you can drop in the OpenEJB war file [1] and get
some EE support added for free with zero extra config and no additional xml.
Should take only a minute or two to get going. You can add EJBs right in
your webapp (no ears required) and get all the transactional support and JTA
EntityManager support, etc. You can even unit test the EJBs with the
embeddable EJB container support.
There is also an example zip on the download page that has an
openejb+hibernate maven/ant project all setup and ready to go.

take a look at the wicket iolite archetype. it uses spring and jpa

Same here: no experience with Guice, but Spring's @Transactional (with the
Connection and TransactionStatus being bound to the current thread etc) is
working just great.
Also the spring helper-classes for junit (or testng) that rollback your
transaction after every test are very convenient.

Yes, but note this:
"The Spring team's recommendation is that you only annotate concrete classes
with the @Transactional annotation, as opposed to annotating interfaces. You
certainly can place the @Transactional annotation on an interface (or an
interface method), but this will only work as you would expect it to if you
are using interface-based proxies. "

I can't comment on Guide as it's not something I've evaluated yet
however I do like some of its idiosyncrasies. I use Spring/Hibernate
as my stack and I find it fits perfectly with Wicket and my domain
models. I personally think Spring offers rich transaction management
with its transaction managers, DAO template classes and generic DAO
exception hierarchy.

As of Spring 2.5, you can configure your beans with non-evasive, fine
grained annotations. It's declarative transaction model is now
annotation based (as of Spring 2.0) so you can make your methods
transactional using the @Transactional annotation and it can even be
declared on an interface. The propagation and isolation can also fine
tuned like:
@Transactional(propagation=Propagation.NOT_SUPPORTED, readOnly=false)
void updateOrderLineQuantities(List<OrderLine> orderLines);
Read this chapter to understand how Spring does transaction management:
http://static.springframework.org/spring/docs/2.5.x/reference/transaction.html

James.

Posted by francisco treacy <fr...@gmail.com>.
one thing you can do is use wicket with guice and hibernate, and have
warp-persist ( http://www.wideplay.com/guicewebextensions2 ) for
transactions.
it's a nice stack that i use, a lightweight alternative to spring. and
no need for java ee containers.
you can have a look here:
http://www.richard-wilkinson.co.uk/2008/04/19/wicket-guice-and-warp-persist/
and here http://code.google.com/p/warp-persist-sample/ .

You can use annotations or spring-javaconfig with Spring if you don't want to
go through too much XML configuration. That criticism is really unwarranted
these days. The annotation-style configuration is very similar to how Guice
works, whereas spring-javaconfig is basically like writing the spring.xml
file in Java code. The latter is nice in that all the wiring is centralized,
but you still get the benefits of working with a Java IDE, such as
refactoring or searching for occurences.
There's probably some easy way to hook Guice up with the Spring transaction
manager, but I've never tried.
And yes, you should be able to run Wicket in an EJB3 Container, but you'll
have to deal with some boilerplate code that will allow you to inject your
EJB3 services into Wicket components...
Personally, I would recommend going with Wicket, Spring and Hibernate (or
JPA) via spring-javaconfig.
