Can anyone explain or point me to a good resource on configuring Glassfish 3.1.1 to use the Equinox 3.7 OSGI runtime, and creating/running some simple OSGI bundle for it? Trying to work my way up to deploying an RAP application on glassfish as OSGI bundle but haven't really been able to get off the ground.
Pretty simple:
Just copy equinox jar (org.eclipse.osgi_$version.jar) to glassfish/osgi/equinox/.
Set an environment variable: GlassFish_Platform=Equinox
Start GlassFish.
Now deploy your OSGi bundles by just copying them to glassfish/domains/domain1/autodeploy/bundles/
For more information, see GlassFish/OSGi guide at

I am trying to embed Felix in an application of ours to handle plugins. Everything is working fine, however, development and debugging is very cumbersome.
Is there a solution where I can tell Felix to automatically reload a plugin bundle or its classes when I recompile a plugin in Eclipse?
I cannot use any OSGi specific launchers because Felix is embedded in our application
Felix' fileinstall supports directories, but expects a specific structure, which is incompatible with the layout of the Eclipse project.
Any help or pointers to a solution would be greatly appreciated.
You could take a look at Bndtools and the remote launcher. You only need to install a remote agent in your framework and then Bndtools can update any bundle that has changed in the workspace.
This is explained in remote launching. In OSGi enRoute you find an IoT tutorial that uses this model as well as a Karaf App Note.
Is there a way to run an OSGi container in the Weblogic Application Server? I know that it works with JBoss, Glassfish and there are possibilities to add an Equinox servlet bridge to your OSGi project (implementation of the bridge is too old). But I want something similar to JBoss/Glassfish functionality where it is very easy to deploy your OSGi environment, because there are already OSGi implementations. Most of the articels I found were very old and there are no more recent ones. Can someone help with hints or better some links?
Maybe Bnd could create a .war file for me, but how can I achieve it. I read there is a possibility. Example would be great!
EDIT
Just for those who still look into that case. Since version 12.1.2 Weblogic supports OSGi out-of-the-box.
I'd consider the Apache Felix Http bridge. It worked a lot better for me than the ancient Equinox bridge (I messed around with it for a while, but never got it to work well), after I switched to Felix I got something working pretty quickly.
If I understand you correctly, you want to make a 'plain' war file, that can be deployed in any Java EE server. If that's the case, there is nothing OSGi about your war file, so I don't think Bnd will do anything for you.
WebLogic now supports OSGi in version 12.1.2 . See this
Ok I'm having quite some issues setting both jbpm and jboss working together...something as simple as running the jbpm process from a servlet is trunning to be a pain and all because jBoss can't find classes.
I made a Dynamic Web Project and didn't use Maven project so things are cleaner...and because it should work.
I just want to load a jbpmn2.0 from the repository in a servlet and run it using a WorkItemHanlder....but I get this:
java.lang.ClassNotFoundException: org.drools.runtime.process.WorkItemHandler
For some reason jBoss can't find a class from jBPM that should work on JBoss. What I did....and I think it's not the right solution...was add the knowledge-api.jar to the WEB-INF/lib. Although I can now deploy the app when I try to run it I get:
Error Unable to instantiate service for Class 'org.drools.builder.KnowledgeBuilderFactoryService'
I Honestly don't get why is it so hard to make a Jboss Web app using jBpm.
You need to make sure all dependencies are on your classpath, this is the same for all Java applications (not just jbpm) and application servers (not just JBossAS).
Which jars did you add? Depending on which features you are using, there could be quite a number of jars that you need to add. One option would for example would be to extract the jars in the jBPM runtime zip that is part of the jBPM downloads into your WEB-INF/lib.
If you use Maven, you would be able to automatically derive all required jars.

Is it possible to run Jboss 4.2.3 as a bundle inside OSGI container? What would be the challenges associated with it?
For those who cares, I am looking at running dcm4chee inside OSGI.
While not impossible it would be incredibly hard, a simpler alternative would be to embed OSGi inside JBoss, see:
http://felix.apache.org/site/apache-felix-framework-launching-and-embedding.html
and
Programmatically Start OSGi (Equinox)?
and
http://njbartlett.name/2011/03/07/embedding-osgi.html
http://www.dcm4che.org/jira/browse/DCM-308 Looks like they're adding support to make the Jars valid bundles - couldn't you just work out the dependencies and deploy these to an OSGi framework? OSGi has support for JMX and JNDI.
Unless there are huge dependencies on JBoss' internals, I'd suggest the second option, but beware of Class.forName usage and other non-osgi-friendly code.
I logged the bug specifically for the dcm4che (note 1 e) toolkits, not the dcm4chee war. I would suggest logging a new issue for the dcm4chee assembly. However, making the dcm4che toolkit components osgi bundles would likely be a required step in the direction of getting dcm4chee to run in an osgi container.
I develop scala application using IntelliJ IDEA. I'd like my application modules to be OSGi bundles.
In Eclipse it is possible to create a project which is both scala project and plug-in project. Eclipse also supports launching of Equinox platform and provides great configuration tool of which bundles to start and how. But I can't use Eclipse because of poor and slow scala plugin, so I need to use IntelliJ IDEA.
In IDEA I tried Osmorc for running OSGi but this solution is very immature and doesn't work well. What are the other ways of launching and configuring an OSGi application from IDEA?
Not an exact answer, but one possibility would be to:
set up a scala project with sbt and Intellij
use bnd4sbt (It enables you to create OSGi bundles for your SBT projects)
use scalamodules (a domain specific language for OSGi development)
(All thanks to the work of WeigleWilczek, including Heiko Seeberger who contributes here)
All the OSGi frameworks can be launched as standard Java processes. For example to launch Felix:
java -jar path/to/felix.jar
To launch Equinox:
java -jar path/to/org.eclipse.osgi_version.jar
And so on.
Unfortunately the initial configuration differs substantially between framework implementations. For Felix you need a config.properties file, which is typically in the conf directory of the Felix installation directory (or you can set the felix.config.properties system property to point it elsewhere).
I'm using PAX runner from inside Intellij IDEA to provision (deploy) OSGI bundles to Apache Felix and run the framework, but this is very annoying: I have to run "mvn install" first, then stop the running pax provisioning session, then restart it - for every change I make in the bundle. There got to be be a better way...
