我試圖設置我的開發環境，並且遇到了很大的問題。 我設置它來運行gwt-gae-maven應用程序，它將使用guice進行依賴注入和requestfactory來保存數據。 我使用了一個API，我在這裏找到https://github.com/etiennep/injected-requestfactory ...這看起來很神奇但不適合我。 Tryed做喜歡這裏http://www.wanderingcanadian.ca/guiced-up-gwt-requestfactory並沒有什麼作品... 當我嘗試運行它作爲web應用我得到這個異常，並沒有什麼作品：在maven-gae-gwt項目中使用guice + requestfactory的情況

另外我嘗試運行它沒有guice，指定servlet直接在web.xml上，但得到了相同的錯誤（但這次不是當我運行應用程序，但是當我啓動它）。
嘗試了很多東西，沒有任何工作......總是有同樣的錯誤。我認爲這只是一個我看不見的細節......我無法繼續下去，直到我修復它......有人知道如何去做？
謝謝。
無法解決它...我的方式來解決它是刪除該項目，並再次啓動...現在它的工作原理，不知道什麼是錯的。 – Kradcifer 2012-02-07 01:08:41
