A questiion on Cafe.init() to build baseUri

[Emily-Jiang]

I see you tried to work out the uri via InetAddress. I am wondering how it will function in Kubernetes. MicroProfile Rest Client offers a good service binding approach, which allows you to override the backend url under a different environment. Can you take a look at this guide to see whether you can use MicroProfile Rest Client. You can define an interface with getAllCoffees() and then annotated with @RegisterRestClient. In your Coffee.java, you can inject that via @Inject @RestClient AInterface.

@PostConstruct
	private void init() {
		try {
			HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext()
					.getRequest();

			InetAddress inetAddress = InetAddress.getByName(request.getServerName());

			baseUri = FacesContext.getCurrentInstance().getExternalContext().getRequestScheme() + "://"
					+ inetAddress.getHostName() + ":"
					+ FacesContext.getCurrentInstance().getExternalContext().getRequestServerPort()
					+ "/javaee-cafe/rest/coffees";
			this.client = ClientBuilder.newBuilder().hostnameVerifier(new HostnameVerifier() {
				public boolean verify(String hostname, SSLSession session) {
					return true;
				}
			}).build();
			this.getAllCoffees();
		} catch (IllegalArgumentException | NullPointerException | WebApplicationException | UnknownHostException ex) {
			logger.severe("Processing of HTTP response failed.");
			ex.printStackTrace();
		}
	}

This is a worthwhile research area, but not something I think that we want to complete before the blog post. I'll leave this open, but we won't work on it just yet.
