Servlet -Dispatcher Ausnahme wirft

Question

Ich habe eine einfache Spring -Web -Flow -Anwendung erstellt. Wenn die Anwendung startet, erhalte ich den folgenden Fehler auf meinem Tomcat -Server:

Ich verwende Spring 2.5.6, Feder Web Flow 2.0.8 mit Tomcat 6.0.20 ...

Jede Idee, warum die WEB_APPLICATION_CONTEXT_ATTRIBUTE Feld ist nicht verfügbar? Wie behebe ich diesen Fehler?

Answer 1

Sie haben immer noch das gleiche Problem mit Ihren Spring Jar -Versionen wie in Feder -Web -Flow -Konfigurationsfehler

RequestContext.WEB_APPLICATION_CONTEXT_ATTRIBUTE war im Frühjahr 2.0 nicht nur in 2.5.6 und später vorhanden.
