How to register a servlet exetension point in program code without xml?
just like registering a service handle:
RWT.getServiceManager().registerServiceHandler(SERVICE_HANDL ER, new ImageServiceHandler());

Hi,

sorry, I didn't understand what you're trying to do. Could explain your
problem a bit more precisely?

Ralf

Thanks for your reply, Sternberg,
I mean that now we can register a rap servlet in extensions tab page in the file plugin.xml and add a extension point, but
if we can register a servlet in programming code just like we register a service handle?
thank you again
David

David,

What you are looking for is OSGi HttpService. It will allow you to register a servlet programatically. The Equinox or OSGi communities may be able to find better support. I think most RAP users utilize ServiceHandler. A quick google search found the following example:

public class Activator implements BundleActivator
{
   public void start(BundleContext context) throws Exception
   {
      ServiceReference sRef = context.getServiceReference(HttpService.class.getName());
      if (sRef != null)
      {
         HttpService service = (HttpService) context.getService(sRef);
         service.registerServlet("/date", new DateServlet(), null, null);
      }
   }

   public void stop(BundleContext context) throws Exception
   {
      ServiceReference sRef = context.getServiceReference(HttpService.class.getName());
      if (sRef != null)
      {
         HttpService service = (HttpService) context.getService(sRef);
         service.unregister("/date");
      }
   }
}

Hope that helps,

Cole
