Hello,
I have developed a proof of concept allowing me to start Equinox within
JBoss
and deploy services (with extensions) that are callable from ordinary JBoss
Web and EJB container objects.
I start Equinox either from an MBean or EJB packaged together with a large
Enterprise Application. Approximately 1/2 of the application will
eventually be implemented within the Equinox Framework.
I am using a hook (implements HookConfigurator, ClassLoadingHook) to
return a Classloader adapter (extends DefaultClassLoader implements
BaseClassLoader) such that the JBoss UCL classloader for the bean is
called for loadClass(String name, boolean resolve). The hook returns the
UCL's parent when called to return the parent.
I've written a series of increasingly complicated tests which all pass.
My questions are:
1) Have I overlooked something important ?
2) Is there a cleaner or more natural way to implement ?
Thanks
Roy

hi roy,
good to see that more and more enterprise applications now are going the
OSGI (equinox) road :-)
wish you luck with your project.
I'm going a reverse way for a lage and complex ERP solution
trying to develope all in OSGI (equinox)
- EasyBeans/OSGI as EJB3 container and Hibernate /JPA
- Eclipse Riena for remote OSGI Services used from my RCP-client
at the moment only rich clients, later also Web
in some weeks I'll know if all works as expected

It makes too much sense to use Equinox this way. At my last job we did
something similar with Felix.
In our case the application has no UI components but does expose
WebServices
and REST services. So we are very purely server side only.
I forgot to mention that the service lookup API I am providing actually
returns
Proxy (java.lang.reflect) wrapped ServiceTracker instances.
Good luck,
Roy
