Examples with WebServer io.helidon.webserver.WebServer used on opensource projects

Example 6 with WebServer

use of io.helidon.webserver.WebServer in project metro-jax-ws by eclipse-ee4j.

the class Main method startServer.

static WebServer startServer() {
    setupLogging();
    // By default this will pick up application.yaml from the classpath
    Config config = buildConfig();
    // Get webserver config from the "server" section of application.yaml
    WebServer server = WebServer.builder().config(config.get("server")).routing(buildRouting(config)).build();
    // Try to start the server. If successful, print some info and arrange to
    // print a message at shutdown. If unsuccessful, print the exception.
    server.start().thenAccept(ws -> {
        System.out.println("WEB server is up! http://localhost:" + ws.port());
        ws.whenShutdown().thenRun(() -> System.out.println("WEB server is DOWN. Good bye!"));
    }).exceptionally(t -> {
        System.err.println("Startup failed: " + t.getMessage());
        t.printStackTrace(System.err);
        return null;
    });
    // Server threads are not daemon. No need to block. Just react.
    return server;
}
