OSGi - Embedded Jetty Server - Servlet unable to get reference to Service Tracker

[Krem Reid]

Hi

I have an OSGi application that has a GWT web interface.

One of the bundles is a GWT bundle that needs to be compiled before the application is launched.

Another bundle is an embedded Jetty application server. It starts the server and points to the compiled WAR of the GWT bundle

Server server = new Server("8080");
		
WebAppContext altHandler = new WebAppContext();
altHandler.setResourceBase("./war");
altHandler.setDescriptor("./war/WEB-INF/web.xml");
altHandler.setContextPath("/");

server.setHandler(altHandler);

server.start();

This works perfect and my GWT is available and it is able to call servlets.

The problem is these Servlets are unable to get a reference to the OSGi container. From what I have read in the init method you can get a reference to a ServiceTracker

public void init(ServletConfig config) throws ServletException {
	super.init(config);
	ServiceTracker st = (ServiceTracker)config.getServletContext().getAttribute("osgi-bundlecontext"));
}

I have no idea where this osgi-bundlecontext is meant to be set in Jetty.

Any ideas?

Thanks

and as soon as I finally post an question I work out the answer

I don't know if this is the best way to do it but it works

BundleContext bundleContext = FrameworkUtil.getBundle(JettyService.class).getBundleContext();
		
Server server = new Server(8080);

WebAppContext webAppContext = new WebAppContext();
webAppContext.setResourceBase("./war");
webAppContext.setDescriptor("./war/WEB-INF/web.xml");
webAppContext.setContextPath("/");
webAppContext.setParentLoaderPriority(true);

webAppContext.setAttribute("osgi-bundlecontext", bundleContext);

server.setHandler(webAppContext);

server.start();
