Ich habe einen Fehler bei einem kleinen Projekt, an dem ich gerade arbeite. Ich habe ein EJB-Projekt auf einem Wildfly Application Server ausgeführt. Dieser Server ist mit einer Oracle-Datenbank verbunden. Dies funktioniert über einen Test-Client, den ich in Eclipse implementiert habe. Allerdings wollte ich die Anwendung über den Webservice verfügbar machen. So implementiert ich einen WebProject und ruft, dass WebProject über einen anderen Client ich die folgende Fehlermeldung erhalten:
Exception in thread "main" com.sun.xml.internal.ws.fault.ServerSOAPFaultException: Client received SOAP Fault from server: WFLYEE0042: Failed to construct component instance Please see the server log to find more detail regarding exact cause of the failure.

Ich habe zusätzliche Klassen für den WebApplicationClient über das wsimport toolkit von Java generiert. Ich kann nicht herausfinden, was das Problem ist. Ich habe diesen Beitrag bereits überprüft: Can not set field to com.sun.proxy.$Proxy aber in meinem Fall FacilityManagerRemote ist eine Schnittstelle und keine Klasse. Ich habe keine Ahnung, wie ich diese Angelegenheit weiter angehen soll. Kann jemand helfen?
