* Class representing an embedded web container, which supports the
* programmatic creation of different types of web protocol listeners
* and virtual servers, and the registration of static and dynamic
* web resources into the URI namespace.
*
* WebContainer service can be accessed using GlassFish instance.
*
* Usage example:
*
*
* // Create and start GlassFish
* GlassFish glassfish = GlassFishRuntime.bootstrap().newGlassFish();
* glassfish.start();
*
* // Access WebContainer
* WebContainer container = glassfish.getService(WebContainer.class);
*
* // Create and add {@link WebListener}
* // By default, when GlassFish Embedded Server starts, no web listener is enabled
* WebListener listener = container.createWebListener("listener-1", HttpListener.class);
* listener.setPort(8080);
* container.addWebListener(listener);
*
* // Create and register web resources {@link Context}.
* File docroot = new File(path_to_web_resources);
* Context context = container.createContext(docroot);
* container.addContext(context, "contextroot_to_register");
*
* // Create and add {@link VirtualServer}
* // By default, when GlassFish Embedded Server starts,
* // a virtual server named server starts automatically.
* VirtualServer virtualServer = (VirtualServer)
* container.createVirtualServer("embedded-server", new File(docroot_of_VirtualServer));
* VirtualServerConfig config = new VirtualServerConfig();
* config.setHostNames("localhost");
* virtualServer.setConfig(config);
* container.addVirtualServer(virtualServer);
