錯誤描述的問題。

使用適當的DOCTYPE爲S2的版本，您正在使用，例如：

<!DOCTYPE struts PUBLIC 
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" 
    "http://struts.apache.org/dtds/struts-2.0.dtd">

現在，沒有任何錯誤，當我開始server..but仍然得到404 error..I檢查eclipse服務器配置，但雙擊服務器..它指向工作區元數據，而不是使用tomcat安裝？ ..那是問題嗎？ – user1050619 2013-03-16 19:29:28

@ user1050619取決於你的設置。一般來說，沒有。 – 2013-03-16 19:33:46

有沒有一種方法來調試這個問題？這是即時通道嘗試的URL --http：// localhost：8080/Struts2Starter/getTutorial.action – user1050619 2013-03-16 19:38:01
