Servlet調度程序拋出異常

我有一個簡單的Spring Web流應用程序創建。當應用程序啓動時，我收到以下錯誤我的Tomcat服務器上：Servlet調度程序拋出異常

我使用Spring 2.5.6，Spring Web Flow的2.0.8和Tomcat 6.0.20 ...

任何想法爲什麼WEB_APPLICATION_CONTEXT_ATTRIBUTE字段不可用？我如何解決這個錯誤？

你有所有需要的罐子嗎？ – Bozho 2010-02-14 07:34:13

是的..我有所有的罐子 - 彈簧，MVC和彈簧網絡流量罐......我實際上修改了春天MVC應用程序到Spring web流量應用程序 – 2010-02-14 07:56:03

你仍然在Spring 2.0中得到了同樣的問題，你的Spring JAR的版本，你在Spring Web flow configuration error

RequestContext.WEB_APPLICATION_CONTEXT_ATTRIBUTE所做的就是不存在的，只是在2.5.6和更高版本。

正是..我使用的是Spring 2.5.6和web flow 2.0.8 ..我不明白爲什麼這個錯誤出現了!!!？ – 2010-02-14 18:01:34

因爲在你的應用程序的某個地方，你有一個Spring 2.0的副本，並且首先被加載。 – skaffman 2010-02-14 19:46:42
