How do I access OSGi bundle classes from JBoss AS?

csetera Apr 19, 2010 11:15 AM

Hello,

We are looking at JBoss-OSGi within JBoss AS 5.x as a way to slowly migrate our application stack over to OSGi. I can't afford the "big bang" of moving everything over at one time, so I would like to move parts of the stack to OSGi but leave things like the WAR resources deployed on JBoss AS while sharing classes from the OSGi bundles. Is this possible? I saw a reference in the Beta 7 documentation about using injection to access the framework, but I'm not sure that I understand what the means or how to actually do that. It seems like if I can get access to the framework, I might be able to reference classes from the framework? Can anyone offer any pointers?

I'd appreciate any insights into how we can best migrate in this way using JBoss AS and JBoss OSGi. If this really isn't viable, I'd appreciate hearing that as well.

Thanks much!

Craig

Hi Craig,

this functionality is currently not supported unless you deploy your webapp also as OSGi bundle. We are looking into this because bridging the component models is one of the ultimate goals of JBoss OSGi.

Please monitor: https://jira.jboss.org/jira/browse/JBOSGI-313

Thomas,

Thanks for your response. I hate to ask this, but I'm wondering if you have any kind of feeling for when Beta 8 might be available with this function?

Thanks,
Craig

The jboss-osgi release cycle is documented here http://community.jboss.org/docs/DOC-14624

According to the JIRA roadmap the Beta8 release is scheduled for 1-Jun-2010
https://jira.jboss.org/jira/browse/JBOSGI?report=com.atlassian.jira.plugin.system.project:roadmap-panel

This issue itself however is still unassigned, which means it may not reliably make it into Beta8.
It's not a trivial task and I suspect you will see plenty of posts in the forum arround it.

I plan to close the Beta8 roadmap sometime next week. Then you should see the issue move/assigned.

Thomas,

Thanks for the insights. I understand these types of things are difficult to schedule for an open source project. I wish I had the chops to help out on this one, but I just don't know the insides of JBoss or the JBoss-OSGi integration well enough to be able to provide any real help.

I will keep an eye on things and cross my fingers!

Thanks,
Craig
