Hi.
Ich bin mir nicht ganz sicher, ob's hierhin gehört, aber ich denke das größte Problem besteht hier in der Datenbankanbindung.
Ich setze aktuell ein Monitoring-System auf (Dynamic Web Project), welches über eine Weboberfläche administriert werden soll. Die einzelnen Aufgaben sollen mit Quartz geplant werden (CronJobs). Ich habe ein initialisierendes Servlet, welches aktuell testweise einen Schedule startet und einen Job plant. Der Job alleine funktioniert, beim Scheduling hakt es insofern, als dass der JDBCJobStore streikt. Ich bekomme eine Exception in Richtung "Datenbankverbindung kann nicht hergestellt werden" (hab schon mehrere Varianten bei verschiedenen Ansätzen und Versuchen erhalten, die aber letztlich immer irgendwie mit der DB zusammenhängen. Interessant ist, dass der Schedule trotzdem irgendwie initialisiert wird nur dazwischen irgendwo was schiefgeht. Na ja, hier die Exception, anschließend meine Quartz.properties. Die wichtigsten Dinge aus dem Servlet/dem Schedule häng ich auch mal an ->
Die Exception (samt bissi Tomcat-Startup-Ausgabe) ->
Die Quartz.properties ->
Der Treiber (derby.jar) liegt auf dem CP vor, daran kann/sollte es eigentlich nicht liegen.
