Ich bin ein Upgrade von Streben-2.3.24.1 zu Streben-2.3.28 und dabei hatten Fliesen von 2.1.2 bis 2.2.2 zu aktualisieren. Ich implementiere auf WebLogic Server 12.1.3. Meine Anwendung ist ohne Fehler mit Maven 3, jedoch gebaut, als ich einsetzen, ist es die folgenden Fehler erzeugt:Struts2-Fliesen-Plugin 2.3.28 - StrutsTilesListener Nullpointer wirft
<User defined listener org.apache.struts2.tiles.StrutsTilesListener failed: java.lang.NullPointerException.java.lang.NullPointerException
at java.io.File.<init>(Unknown Source)
at org.apache.struts2.tiles.StrutsWildcardServletTilesApplicationContext.<init>(StrutsWildcardServletTilesApplicationContext.java:53)
Nichts hat sich in der Anwendung geändert, da es mit Streben 2.3.24.1 gearbeitet. An dem Speicherort, auf den in der Datei "tiles-defs.xml" verwiesen wird, befinden sich JSP-Dateien. Ich habe viele verschiedene Ansätze versucht, dies zu beheben, aber immer den gleichen Fehler zu bekommen. Ich habe auch dieses spezielle Thema, das vorher besprochen wurde, nicht gesehen. Was muss ich noch mit seinem speziellen Upgrade ändern? Was vermisse ich?
Danke,

Edit: das ist nicht im Zusammenhang mit dem, was ist eine Null-Zeiger-Ausnahme Frage in den Kommentaren Bezug genommen wird, denn dies ist ein Problem mit Streben und Kacheln Konfigurationen.
Edit 3/31/2016: Ich habe Remote-Debugging eingeschaltet und festgestellt, dass der Kontext alle geeigneten Pfade (siehe Bild unten) hat. Allerdings Linie 53 von StrutsWildcardServletTilesApplicationContext.java die context.getRealPath() zurückkehrt null, da es nicht den absoluten Pfad zu dieser Ressource erhalten. Der Kontextpfad ist auch innerhalb des Kontextobjekts korrekt. Ich habe gelesen, dass die Funktion getRealPath() null zurückgeben kann, wenn sie den virtuellen Pfad nicht in einen echten Pfad übersetzen kann, der auftritt, wenn Dateien von einem WAR kommen. Wie korrigiere ich das?
Versuchen Sie, den '' fallen lassen, wenn das nicht hilft bitte einen Fehler in JIRA registrieren https://issues.apache.org/jira/browse/WW –
Update dtd-s, Drop-Kontext-Parameter Stellen Sie sicher, dass keine alten Versionen auf dem Server vorhanden sind. Debuggen Sie Ihre App, um herauszufinden, was null ist. –
