As said in the article, JOnAS 5.0 relies on a pure OSGi architecture. Main advantages are dynamic services enabling to reconfigure them at runtime, JEE/OSGi gateway, extensibility, pluggability. Furthermore, with EasyBeans (JOnAS's EJB3 container, http://www.easybeans.net), EJB3 modules can be deployed as OSGi bundles.

You'll get more information in the white paperavailable on the JOnAS web site here : http://wiki.jonas.objectweb.org/xwiki/bin/download/Main/Documentation/JOnAS5_WP.pdf

Towards Spring Application

Towards Spring Application Server? Does history repeat itself? Is someone going to write a book called "Enterprise Java Development without Spring" soon?

@fg82183

Geronimo is only now starting to move towards OSGi, http://blog.hogstrom.org/?p=17. How then, can something like WebSphere get its OSGi support from Geronimo? WebSphere uses Equinox which comes from the Eclipse Foundation.

Equinox is open source but I fail to see how that is relevant. Software licensing doesn't change its functionality. If I deploy, for example, a .war to WebSphere, I can not access WebSphere's OSGi services from my app. This makes the fact that WebSphere use OSGi absolutely meaningless to an application developer. Yes I could deploy an OSGi bundle to WebSphere by placing it in WebSphere's /plugin directory (the same you deploy plugins to Eclipse) but how our the incompetent system administrators in our org going to manage my OSGi bundle let alone deploy it?

I didn't know about that.

I didn't know about that. Good point!

Ahem, WEbsphere uses

Ahem, WEbsphere uses Apache Geronimo for their OSGi..last tiem I checkled Apache Geronimo was opensoruce..

Maybe it won't, but if you

Maybe it won't, but if you look at Rod's blog you will see they have people commiting to Apache projects.

Btw, I've asked this question on another forum.

I know that WebSphere 6.1

mheath — Tue, 29 Jan 2008 12:42:02 -0500

I know that WebSphere 6.1 is built on Equinox but is there any way for the applications I deploy to WebSphere to gain access to Equinox services? I haven't seen any documentation for this. The only way I know of to deploy OSGi components to WebSphere is to copy the OSGi bundle to the WebSphere plugins directory (the same way Eclipse plug-ins are deployed). There not much utility here from the appliction developer point of view.

Am I missing something? Is there some way I can take advantage of OSGi and it's dynamic reloading from my web applications that are deployed to WebSphere?

SpringSource didn't acquire

SpringSource didn't acquire Tomcat, it acquired expertise. I don't think it will cause such an overhaul in Tomcat's internals. And even if SpringSource decided to build a OSGi deployment platform (what is not likely), it would probably happen at the level of Spring, in an application server-independent manner.

This is just the beginning of OSGi on the server. As initiatives such as Server-Side Equinox mature, they will surely provide convenient means for deploying modules dinamically.
