EclipseLink 2.6.1 (final) löst die folgende Ausnahme aus, wenn eine Java EE-Anwendung auf GlassFish Server 4.1 bereitgestellt wird. Dies war vor dem Upgrade von 2.6.0 nicht geschehen.java.lang.NullPointerException bei org.eclipse.persistence.platform.server.ServerPlatformUtils.createServerPlatform (ServerPlatformUtils.java)

Obwohl es ein java.lang.NullPointerException, die LOG Ebene ist Warning.
org.eclipse.persistence.sessions.factories.SessionManager#init() ist wie folgt definiert (obwohl grepcode RC1 zeigt).
74 private static void init() {
75 String platformClass = ServerPlatformUtils.detectServerPlatform(null);
76 try {
77 detectedPlatform = ServerPlatformUtils.createServerPlatform(null, platformClass, SessionManager.class.getClassLoader());
78 } catch (NullPointerException npe) {
79 //some platforms may not be handling 'null' session well,
80 //so be defensive here and only log throwable here
81 detectedPlatform = null;
82 LOG.logThrowable(SessionLog.WARNING, AbstractSessionLog.CONNECTION, npe);
83 }
84 supportPartitions = detectedPlatform != null && detectedPlatform.usesPartitions();
85 if (supportPartitions) {
86 managers = new ConcurrentHashMap<String, SessionManager>(4, 0.9f, 1);
87 SessionManager sm = initializeManager();
88 manager = sm;
89 managers.put(sm.context, sm);
90 } else {
91 manager = initializeManager();
92 }
93 }
Wo createServerPlatform(DatabaseSession session, String platformClass, ClassLoader loader) wirft ein java.lang.NullPointerException, wenn platformClassnull ist.
97 public static ServerPlatform createServerPlatform(DatabaseSession session, String platformClass, ClassLoader loader) {
98 if (platformClass == null) {
99 throw new NullPointerException();
100 }
//...
}
Es scheint nach dem Code normal zu sein. Ist es?
Wie setzen Sie Eclipselink bei Glassfish ein? –
Wie üblich mit einer IDE, NetBeans in diesem Fall, die einen Deployer namens Apache Ant (ich benutze keine Apache Maven), die die Aufgabe der Bereitstellung von Anwendungen. – Tiny
Sie wissen, dass Glassfish bereits eine andere Version von Eclipselink implementiert (ich denke, 2.5.2)? Haben Sie die Glassfish-Implementierung geändert, um mit 2.6.1 zu arbeiten? Wenn Sie das Glas zu einem Krieg hinzufügen, den Sie auf Glassfish bereitstellen, kann es zu Versionskonflikten kommen. –
