Ho creato una semplice applicazione di test:Vaadin NON spingere disponibile con tomcat8 incorporato
import java.util.logging.Logger;
import org.apache.catalina.Context;
import org.apache.catalina.LifecycleException;
import org.apache.catalina.startup.Tomcat;
public class Main {
private final static Logger LOGGER = Logger.getLogger(Main.class.getName());
private final static String mWorkingDir = System.getProperty("java.io.tmpdir");
private static Tomcat tomcat = null;
public static void main(String[] args) {
tomcat = new Tomcat();
tomcat.setPort(8080);
tomcat.setBaseDir(mWorkingDir);
tomcat.getHost().setAppBase(mWorkingDir);
tomcat.getHost().setAutoDeploy(true);
tomcat.getHost().setDeployOnStartup(true);
try {
tomcat.start();
} catch (LifecycleException e) {
LOGGER.severe("Tomcat could not be started.");
e.printStackTrace();
}
LOGGER.info("Tomcat started on " + tomcat.getHost());
// Alternatively, you can specify a WAR file as last parameter in the following call e.g. "C:\\Users\\admin\\Desktop\\app.war"
Context appContext = Main.getTomcat().addWebapp(Main.getTomcat().getHost(), "/app", System.getProperty("user.dir")+"\\Whys.war");
LOGGER.info("Deployed " + appContext.getBaseName() + " as " + appContext.getBaseName());
tomcat.getServer().await();
}
public static Tomcat getTomcat(){
return tomcat;
}
}
Quando inizio a questo da Eclipse, tutto funziona bene, ma quando esporto ad un barattolo eseguibile ed eseguirlo ottengo questo errore:
HTTP Stato 500 - com.vaadin.server.ServiceException: java.lang.IllegalStateException: push non è disponibile. Vedere i messaggi di registro precedenti per ulteriori informazioni.
Ecco l'intero stack di chiamate:

AVERTISSEMENT:
=================================================================
Atmosphere could not be loaded. When using push with Vaadin, the
Atmosphere framework must be present on the classpath.
If using a dependency management system, please add a dependency
to vaadin-push.
If managing dependencies manually, please make sure Atmosphere
2.1.2.vaadin6 is included on the classpath.
Will fall back to using PushMode.DISABLED.
=================================================================
Ho provato ad aggiungere javax.websocket-api-1.1.jar alle librerie, ma non è cambiato nulla, lo stesso errore ancora.
Non so dove sia il problema, forse ho bisogno di aggiungere qualcos'altro, ma al momento non so cosa.
EDIT:
Non faccio uso di Maven/Gradle, per il tomcat8 incorporato ho scaricato on tomcat8 website tutto il necessario, e per la guerra applicazione di test che ho usato uno dei miei progetti, lavorando bene con Tomcat8 non incorporato.
Ci scusiamo per una domanda banale, ma hai aggiunto correttamente vaadin-push al tuo progetto (Maven, Gradle ...)? Se usi Maven, potresti darci anche un albero delle dipendenze. – jsosnowski
