I'm currently in need of deploying a legacy plugin (developed for plain Equinox / HttpService) onto virgo 2.1.0. I've noted that the standard HttpService.registerServlet() API does not work (there is no HttpService).

I don't want to bolt another web server (like Jetty, as I've read in the forums) into Virgo so before I put on a new strategy I'd like to know about these:

there is no way for a plugin to register a Servlet, either using the HttpService API or a-la PAX-web (register a javax.servlet.Servlet OSGi service): is it true? Will be supported in future versions?
I've to convert the bundle into a web-bundle and register my servlet using the web.xml? Is there any issue in doing this and having to reference OSGi services? Is there any example I can look at?

Thanks for any hint (or just reading Wink

) !

Hi,

Find attached a very simple web app that lists the bundles on the system.
Put the .war file in the pickup directory then start Virgo.
When everything is started, request the application in the browser - http://localhost:8080/osgi-web-app

Two important things are:
- you can get the BundleContext from the ServletContext

(BundleContext) getServletContext().getAttribute("osgi-bundlecontext");

having the BundleContext you can use OSGi services

- you can specify the context path in the Manifest.mf

Web-ContextPath: /osgi-web-app

About HTTP service you may want to read this blog [1], some parts of it may be helpful.

Regards,
Violeta
