在tomcat上部署的war文件給出了404錯誤

Question

我已經使用ant build.xml文件成功地將我的小型web應用程序的war文件部署到我的本地tomcat 7.0.42服務器。當我輸入網址到我的應用程序localhost:8080/springapp/index.jsp時，出現404錯誤。我不明白爲什麼當部署war文件時出現錯誤。

我知道我的部署成功了，因爲我可以看到在tomcat管理器應用程序localhost:8080/manager中列出的/springapp。我一直在關注本教程，http://docs.spring.io/docs/Spring-MVC-step-by-step/part1.html，幾乎完全改變了一些東西，因爲我使用的是tomcat 7，它使用的是tomcat 6.我目前正在步驟1.4。 任何幫助將不勝感激，我一直堅持在這個問題上超過一天的谷歌搜索和故障排除。

這裏是我的build.xml：

我解決了這個問題。當它應該是/webapps/springapp/index.jsp時，我的index.jsp文件位於/webapps/springapp/WEB-INF/index.jsp。愚蠢的錯誤。謝謝你的幫助JB Nizet。
