How to create a simple WAR file with OSGI module

Question

I'm new to Web java programming. I want to create a simple JSF modular application. I found a simple tutorial link but unfortunately I still have some questions how to use OSGI: Can I create a simple OGI bundle and place in it some JSF pages? If not how usually web applications are developed. Can you give me link with example how I can call functions and pass arguments form a WAR file to OSGI module.

Not an answer specifically for JSF (this might be), but for OSGi web-apps in general take a look at Pax-Web if you're using maven. The easiest way to get started with Pax-Web is probably to use Karaf and then run the command features:install war Once a WAR (or WAB - Web App Bundle) is deployed you'll be able to use the osgi-bundlecontext attribute in Servlet initialization, eg: extends HttpServlet { BundleContext bundleContext; @Override public void init() throws ServletException { bundleContext = (BundleContext) getServletContext().getAttribute("osgi-bundlecontext"); } Using this you can look up services in the OSGi registry. You'll need to pay attention to the bundle's MANIFEST.MF entries, two in particular: Bundle-ClassPath: ./,WEB-INF/classes Webapp-Context: context-root-name-here Or in an OSGi compliant WebApp container you'll need to add: Web-ContextPath: context-root-name-here There's more info in the specifications, see the enterprise or compendium PDFs for v4.2 EDIT: For deploying in JBoss you'll most likely want to use the WAB support, see section 128 of the enterprise 4.2 spec. Also this may help: http://community.jboss.org/message/619443 Interestingly JBoss AS7 is using pax-web, so the documentation for this should largely apply too.
