vaain 7 - osgi contribution

Vaadin 6 / 7 / 8
1

Currently i am writing a contribution for vaadin to provide OSGi services that allow to register SessionInitListeners at the vaadin core.

Any hints and discussions are welcome.

Any progress in this Topic?

I’m interesting an OSGI solution for Vaadin 7.

As far my Idea is based on the #10061 Ticket is the following:

extend the VaadinServlet and override the servletinitialized Method, and add a custom SessionInitListener.

	@Override
	protected void servletInitialized() throws ServletException {
		super.servletInitialized();
		super.getService().addSessionInitListener(new OSGISessionInitListener());
	}

This custom sessionInitListener can provide the custom UIProvider for Vaadin like this:

public class OSGISessionInitListener implements SessionInitListener {
	@Override
	public void sessionInit(SessionInitEvent event) throws ServiceException {
		event.getSession().addUIProvider(uiProvider);

	}
}

As far as I see the problem is with this solution, it is not handling the osgi bundle dynamism.
