Eclipse中的Tomcat - HTTP狀態404請求的資源不可用

我即將失去理智。Eclipse中的Tomcat - HTTP狀態404請求的資源不可用

我按照這裏的教程

我有這個index.html文件

<!DOCTYPE html> 
<html> 
<head> 
<meta charset="UTF-8"> 
<title>Insert title here</title> 
</head> 
<body> 
<h1>Hello World</h1> 
</body> 
</html>

而且web.xml文件

兩個文件在t他WebContent文件夾

我可以毫無問題運行Tomcat和

http://localhost:8080/

工作正常，但是當我運行應用程序或去

http://localhost:8080/ServletTutorial/

或

http://localhost:8080/ServletTutorial/index.html

它給404錯誤請求的資源不可用。

我已經配置Tomcat以使用Tomcat安裝。

我快要崩潰大哭......我已經困在這裏了兩天:(

這兩個文件都在WebContent文件夾中 - 實際上web.xml必須位於WebContent/WEB-INF文件夾中。 – ike3

我想輸入xml文件代碼，但它不允許我0_o – NoobNe0

沒有得到最後的評論。有沒有錯誤？ – ike3

的應用無法部署到Tomcat，因爲沒有日誌記錄，如

Deployment of web application directory ... ServletTutorial

當你配置Eclipse來使用Tomcat的安裝嘗試檢查Tomcat的web應用程序文件夾 - 應該有ServletTutorial目錄與應用程式文件檢查根據教程其完整性。如果它不存在，刪除應用程序和補充。它再次執行或使用「清理」菜單選項完全重新發布e服務器窗口。

我建議不要混淆tomcat安裝目錄，但配置它使用工作區元數據文件夾。然後，只有您的應用程序將開始與我的經理，例子和其他不必要的應用程序減少您的發展週期時間。

我已經刪除了服務器並創建了新的，現在它可以工作！因此，我所遵循的教程是錯誤的，因爲您說web.xml文件必須位於WEB-INF文件夾中，而不是位於帶有index.html的Web內容中，對嗎？此外，即使應用程序工作，我檢查了Tomcat/webapps，並且沒有Servlet教程目錄。這是爲什麼？ – NoobNe0

這是因爲新服務器配置爲使用.metadata文件夾，而不是webapps目錄。您可以在'.metadata \ .plugins \ org.eclipse.wst.server.core \ tmp0 \ wtpwebapps'附近找到您的應用程序 – ike3

我注意到每次添加一個新的java類時，我都必須刪除並重新創建服務器否則我得到資源未找到錯誤。這是爲什麼？無論如何，這個問題可以避免，而不必刪除和重新創建服務器所有的時間？ – NoobNe0
