Nach der Bereitstellung von WAR-Datei, Verbindung mit Datenbank in Glassfish

Question

Ich bin sehr neu zu Java-EE in der Schule und nach dem Versuch, mein Projekt, die perfekt funktioniert mit Datenbank-Verbindung in Netbeans IDE funktioniert. Ich habe versucht, die * .war Datei auf dem lokalen Host-Server ohne das Öffnen von Netbeans IDE (Server gestartet mit Befehl als Admin Start-Domain Domain1 und die * .war Datei ist in der Anwendungsliste) und nach I starte das Projekt im localhost: 8080, die Datenbankverbindung ist fehlgeschlagen und meine Web-App würde nicht funktionieren.

Hat jemand eine Idee, wie man es löst? Exception picture

Answer 1

versuchen, mit der Lookup-Syntax, wie unten zu ändern:

ds = (DataSource)ctx.lookup("java:jdbc/fastfood"); 

Answer 2

in Java EE Sie sollten nicht Nachschlag Sie die Verbindung manuell, aber verwenden Sie eine Datenquelle (https://docs.oracle.com/javase/8/docs/api/index.html?javax/sql/DataSource.html) in Ihrem Anwendungsserver konfiguriert.

Sie können dann die Datenquelle wie hier beschrieben in Ihre Komponente injizieren: https://docs.oracle.com/javaee/6/tutorial/doc/bncjk.html. Als Alternative können Sie eine JNDI-Suche ausführen, um die Datenquelle abzurufen.

Wenn Sie JPA verwenden für den Datenbankzugriff Ihre Verbindung würde, indem er seinen JNDI-Namen in der persistence.xml erworben werden, und Sie würden nur einen Verweis auf die EntityManager über @PersistenceContext Anmerkung (https://docs.oracle.com/javaee/7/api/javax/persistence/PersistenceContext.html)
