Try searching for "spring framework" . Here's their list, with seperate topics for ejb, mvc, web services, data access - just about everything:
http://forum.springframework.org/index.php
Probably spring's biggest use is with the ORM framework Hibernate.
What spring does, in a nutshell, is 'dependancy injection', or aspect orientated programming (AOP). Simplified, spring allows easy testing of EJB and in general everywhere else, transactions without ejb (ie tomcat), pluggable abstraction of the db layer, simplified use of hibernate, mvc without struts, a pretty good security solution, and best for me - no factories to resolve which class fits where. IMHO Spring makes it more difficult to make bad architecture decisions on a medium sized project.
Searching on spring's mailing list shows 155 entries for 'axis' . They have support for axis 1.x but it requires jax-rpc , which axis2 doesn't support. I myself answer questions on this list about spring once a week or so.
In my view a good way to judge a technology is by want ads. At least in Brazil 90% of the announcements I see require spring knowledge.
So how has axis2 supported spring up until now? With a spring class called a BeanFactory - which allows access of spring controlled beans anywhere - useful for places like taglibs and junit which can't be wired by spring. This, however, is somewhat advanced and too difficult to configure for an average user.
In a web service you don't need this wiring / dependancy injection capability quite as much as in other places. But it still is needed by spring users.
As stated, I'd be perfectly happy having Spring capability in a place where users who don't want it, don't have to carry it around.

"I know it when I see it" β and Spring is over the line. J
How many Axis2 users will use Spring? Hard to say, but I am betting that <1% of users are using it right now.
I am happy to have 'extra' code in axis2.jar that supports lots of other technologies. That isn't a steep price to pay. But if I am using the 'basics' β SOAP processing, the Axis Data Binding, WSDL generation, maybe WS-Addressing β I should have a small list of jars that I need to run (whether the list is small right now is probably another discussion).
Doesn't that sound right?
P.S. I am only dimly aware of Spring, I don't even know what it really does without a Google search, so I have nothing against Spring itself.

Sure, I understand - that's why I proposed bringing back the extensions directory. The problem is, however, where do you draw the line?

Robert,
Ok, good then as a starting point we can use your code base as you have already done some work on pauls stuff.
Yes the 2MB depency does concerns me as well. But it looks like a lot of developers are using spring so it might not be that much of an issue considering the fanfare we see out there for spring.
How about pulling put the common code and refactoring the Message Receivers? or you want to wait till u check in the stuff and then look at it?
I am not sure about Data binding as well and hopefuly somebody will fill in the gap here.

I've been using Spring with axis2 since .92, although in a way not everybody seems to like.
I'm working a lot on adding Spring support via a Message Reciever, but wanted to wait till post 1.0 . . I've mostly got it working. I'm basing this work of of paul's work he did last july though some things cleary won't work today as they were coded back then. I'm hoping to have something ready to commit this week, of course after discussions on the list. I still need to do the junit tests and work out how spring does annotations.
This is good time to lay out the issues:
1) Spring is licensed under apache 2.0 .
2) Its yet another dependancy, the main spring.jar being about 2 megs.
3) We had an extensions directory, and this may be a good time to bring it back.
4) I'm unsure how to integrate a spring message reciever with databinding. Databinding at least for me is a critical factor.

Dims,
Thats true, we cannot and should not try to satisfy everybody.
Most people are looking for a magic wand that will create there code with minimum effort as possible.
Reading the thread on TSS I was sad to see that most people have missed the boat about Web Services.
These people expect nothing but to expose their **objects** as Web Services using some framework with minimum effort as possible.
Thats as far as they are willing to go with Web Services.

Sure.
- Beware of people with hidden agendas. You can never please everyone.
- Once you meet the objective criteria (say "add spring support"), you
will hear either ("it's not easy" or "it's complicated" in other words
"It does not meet my unspecified standards that are in my
head"-kind-of subjective criteria.
thanks,
