Microcontainer @ JavaOne
26. May 2009, 03:45 CET, by Aleš Justin

This year there will be huge presence of Microcontainer releated material at JavaOne.

To start off, I'll do a lightning talk at Drools boot camp on Monday June 1st.

Also on Moday, Scott Stark will present the new Virtual Deployment Framework, and I will share some tips and tricks on how to optimize MC's usage.

On Tuesday Scott will continue to share his MC experience with component model mixture patterns, and on Wednesday you can hear me talk about the new ClassLoading layer and our plans with OSGi.

With your head full of MC you'll probably be eager to share this knowledge at the famous JBoss party, not to mention the free drinks and a chance to grab core developers by the sleeve. ;-)

To wrap it all up, leaving the best for last, a whole hour of technical MC talk :-)

And the most important info, don't forget to ask for a MC T-shirt at our booth! :-)

JBossAS5.1.0.GA released
26. May 2009, 03:17 CET, by Aleš Justin

In case you missed the announcement, which is highly possible as I think the main voice behind AS, Dimitris, is driving with his motorcycle across Europe and the US team is enjoying a day off with national holiday.

So, the make the long story short, here is your latest and greatest, JBossAS 5.1.0.GA.

Enjoy!

Fresh 1.0.0.Alpha1 - CLI for JBossAS
15. May 2009, 22:01 CET, by Aleš Justin

I'm proud to present the initial version of Fresh, CLI for JBossAS.

This is definitely not the only CLI developed under our roof (see adminclient repository) but it brings a ton of interesting stuff developed by the people who donated it, my friends from Parsek company, Tomaz Cerar and Marko Strukelj (yes, the one who's responsible for vfszip :-)).

This is the JIRA release issue, where you can learn more about it, download the deployable artifact, etc

A simple user guide can be found here

Any additional ideas can be published here:

Basically the idea is to drop in the jboss-fresh.jar into deploy/ and then connect to it via ssh, port 2022. Currently there is no user/pass, simply press Enter.

Fresh is installed On_Demand, only ssh server deamon is fully installed at the beginning, the rest kicks in when you first connect (thanks Bela for the tip).

Marko and Tomaz already have plans to make this even better, and I'll be there to help with some fancy MC tricks. :-)

Enjoy, any feedback is welcome.

ps: this was also posted on the jboss-dev mailing list, so we can easily continue the discussion there

MC's DI\IoC article, JBVE and JBoss5 VFS cache usage update
09. Jan 2009, 20:43 CET, by Aleš Justin

Although this is old news, just to make a simple blog announcement,
DZone posted my MC part II. article, the title is Advanced Dependency Injection and IoC.

It's about how we do DI/IoC in MC, not what others don't do.
The advanced notion relates to usage beyond simple attribute/property injection.



For all those who missed JBVE announcement on other blogs, here is the link:

I hear the speakers are great. ;-)



And I'm sorry to admit we found our first ugly bug in JBoss5. :-(

There is already an ongoing discussion on the forum

And yesterday I hacked this new impl of VFS cache

It's a combination of permanent entries (the main roots) + real cache for any other possible new roots.
I'm already running some simple long running tests on my home server to check how this new cache handles the issue,
but any real life/scenario feedback is more than welcome - simply post your results to some of the before mentioned existing forum posts.

Microcontainer goes 2.0.0.GA
28. Nov 2008, 19:43 CET, by Aleš Justin

What better time to start blogging here as on the day we push our 2years+ work out as GA ready.
By our work I mean JBoss Microcontainer project, MC for short name. ;-)

So, I'm happy to announce that we've finally went 2.0.0.GA with MC.

  • Reflect 2.0.2.GA
  • VFS 2.0.0.GA
  • MDR 2.0.1.GA
  • Managed 2.0.0.GA
  • Kernel 2.0.2.GA
  • ClassLoader 2.0.1.GA
  • Deployers 2.0.3.GA

And the piece that binds my blog with other Seam bloggers

All MC sub-projects are fully mavenized, hence making it super easy to use.
We're a bit behind with documentation, but we'll be happy to help you on our forums:

For some light reading / coding check my DZone article along with its demos:

JBoss people blogging about it:

Cool customizations

And for all who will be at Devoxx, come and grab me if you wanna talk about MC. ;-)
