You need a JSP/Serlvet container that can server JSP pages for you. There a number of JSP/Servlet containers available and used but the most commonly used is Apache Tomcat.
您需要一个可以为您提供 JSP 页面的 JSP/Serlvet 容器。有许多 JSP/Servlet 容器可用和使用，但最常用的是Apache Tomcat。
To setup Tomcat,
要设置 Tomcat，
- simply download it and extract it into any folder
- Next, place your application inside the webapps folder
- Start the server.
- Open your browser and browse to URL
http://localhost:8080, it should open the tomcat's default page - Package your application as war, and place it in the webapps folder of tomcat
- Now Access the URL
http://localhost:8080/YourApplicatioContext/path/to/jspFileand you will see your JSP file being compiled and served in the browser
- 只需下载它并将其解压缩到任何文件夹中
- 接下来，将您的应用程序放在 webapps 文件夹中
- 启动服务器。
- 打开浏览器并浏览到 URL
http://localhost:8080，它应该打开 tomcat 的默认页面 - 将你的应用打包成war，放到tomcat的webapps文件夹中
- 现在访问 URL
http://localhost:8080/YourApplicatioContext/path/to/jspFile，您将看到您的 JSP 文件正在编译并在浏览器中提供

You need servlet container, connector component and the JSP engine to run JSP pages.In case of tomcat, Catalina is actually the servlet container. Coyote is the connector that handles the requests and forwards them onto Catalina. Web Pages are then delivered dynamically through Jasper, the JSP engine.
您需要 servlet 容器、连接器组件和 JSP 引擎来运行 JSP 页面。在 tomcat 的情况下，Catalina 实际上是 servlet 容器。Coyote 是处理请求并将它们转发到 Catalina 的连接器。然后通过 JSP 引擎 Jasper 动态传送网页。
