jboss 7 microcontainer

[jjakub]

jboss 3,4 used microkernel based on jmx,

jboss 5,6 used microcontainer,

what is used in jboss 7 ?

is it the same architecture as in 5,6 - microcontainer,

or is it other attitude ?

does below link describe jboss7

https://access.redhat.com/site/documentation/en-US/JBoss_Enterprise_Web_Platform/5/html-single/JBoss_Microcontainer_User…

, or

this is for jboss7 : JBoss Microcontainer 2.0.0 Beta9

?

if above are bad, where is microcontainer for jboss7 described ?

AS7 was complete redesigned and rewritten from scratch and is no longer based on MC/JMX kernel.

It is now based on jboss modules & MSC.

see AS 7 Internal Architecture Overview for more.

Thx, Great article.

Do you know sample simple web application that cannot be run on jboss6/5

but  can be run on jboss7 laveraging jboss 7 msc modular classloading container?

[david.wilson]

Nearly every simple application can be run on jboss6.

will you tell me that which simple web application is not running?

[jjakub]

I thought that app, which

     has dependency to two libraries, each of them has dependency to different version of the same library (eg hibernate) and one of them make use of deprecated api which is removed from newer version of hibernate,

will not run on jboss 6 or tomcat7,

but may somehow be run on jboss 7 ( because it is osgi with multiple classloaders and modules ).

David, please explain where am I wrong.

Yes it will run on AS7 with proper configuration, but not because of OSGI but because of the way jboss modules work. Osgi is just an add-on on top of core functionality.

Read more about how to configure classloading for your deployments to use different sets of modules.
