What can the MicroContainer do for me?

tszymanski Aug 18, 2008 4:20 PM

Hello,
I am currently evaluating various Jboss technologies and the MicroContainer (MC) looks very promising. I have a few question I'd be appreciate if someone could answer.
1. Is the MC similar in concept to Spring ?
2. According to documentation, I don't need App Server to run MC. How do I use MC if I also want to use web tier (JSP, JSF, Servlets)?
3. What is the possible integration between MC and
3.1 Drools
3.2 Jbmp
4. Can the MC run as another module within App Server so the integration mentioned above would be seamless.
5. On the subject of seamless, can the MC be used within Seam?

Thanks in advance for any help
-Tom

First, I would appreciate if you don't cross-post in the future.
Design forum is not _user_ forum. ;-)

What do you consider as Spring concept?
If you mean IoC, then yes.
But it's much more, perhaps more like Spring's SSAP.
Check the MC's home page, to see the full list of sub-projects.

JBoss Embedded project does that for you,
but unfortunately it's not maintained properly.

It's all about how you do MC bootstrap.
Here's a couple of examples on how to do this:
- http://anonsvn.jboss.org/repos/jbossas/projects/demos/trunk/bootstrap/src/main/org/jboss/demos/boostrap/Main.java
- http://anonsvn.jboss.org/repos/jbossas/projects/jboss-deployers/trunk/deployers-vfs/src/tests/org/jboss/test/deployers/BootstrapDeployersTest.java

Perhaps using something like that + porting some stuff from Embedded should do the trick.

I started working on this:
- http://www.jboss.com/index.html?module=bb&op=viewtopic&t=117607
And I still got some ideas on how to extend this:

MC _is_ the kernel of App Server,
so everything should already be seamless. ;-)

I also started working on this,
but at that time I didn't like how the integration was done:
- https://jira.jboss.org/jira/browse/JBSEAM-247
But with these new features, things should be trivial to integrate:
- http://www.jboss.com/index.html?module=bb&op=viewtopic&t=139595
- http://www.jboss.com/index.html?module=bb&op=viewtopic&t=139312
As a matter of fact, I just started working on it :-)
