HTTP 500 javax.servlet.ServletException：文件未找到

Question

我正在開發一個J2EE應用程序，它在從eclipse運行時工作正常，但是當我在tomcat上部署它時，出現以下異常，我不明白原因是什麼原因我需要刷新幾次，直到頁面顯示

（eclipse在試圖導出戰爭時返回空文件，所以我通過複製tomcat/webapps/my項目中的WebContent中的所有文件進行部署，並且我將類WEB-INF）

Etat HTTP 500 - javax.servlet.ServletException: Le fichier "/menu_dashboard_top.jsp" n'a pas été trouvé

menu_dashboard_top.jsp是的WebContent，它不是一個servlet只是包含了我包括菜單中的JSP頁面在我的所有網頁中

我已經在web.xml中映射了所有我的servlet。這是我的web.xml文件
