Eclipse java-web项目，学习Cookie时，出现Cookie Cannot be resolved to a type问题。
(1) 尝试导入Cookie包：<%@ page import="javax.servlet.http.Cookie" %>
问题并未解决，Cookie处仍然提示Cookie Cannot be resolved to a type，而且在Cookie包语句上提示：The import java.servlet cannot be resolved，这其实是软件包java.servlet不存在，从tomcat中导入就可以了。
(2) 其次，右键项目-->Build Path-->Configure Build Path --> Libraries -->Add Library
(3) 选择Server Runtime，单击Next按钮，再选择服务器(如Apache Tomcat v9.0)，单击Finish按钮完成
