Running JSP files with tomcat 7
提问by Bernice
Hi I just installed Apache Tomcat 7 and got the server running OK. When I entered localhost:8089 (8089 being the port I assigned to Tomcat 7) the apache website popped up and I got to run some jsp examples and they opened correctly.
嗨，我刚刚安装了 Apache Tomcat 7 并且服务器运行正常。当我输入 localhost:8089（8089 是我分配给 Tomcat 7 的端口）时，apache 网站弹出，我必须运行一些 jsp 示例并且它们正确打开。
However now I wish to create a jsp file myself (I am trying tutorials for the very first time) and when I open them, only the source code I written is showing in the browser.
但是现在我想自己创建一个jsp文件（我是第一次尝试教程），当我打开它们时，浏览器中只显示我编写的源代码。
The example I am trying is this:
我正在尝试的例子是这样的：
<html>
<head>
</head>
<body>
Hello World. <%= new java.util.Date() %>
</body>
</html>
and all I'm seeing in Chrome is : "Hello World. <%= new java.util.Date() %>"
我在 Chrome 中看到的是： "Hello World. <%= new java.util.Date() %>"
I am saving this file in this path:
我将此文件保存在此路径中：
C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\host-manager\WEB-INF\jsp
In WEB-INF there is an index.html file ready.
在 WEB-INF 中有一个 index.html 文件准备好了。
Am I doing something wrong? Where am I supposed to save my file? I tried watching tutorials on youtube but most of them were in arabic and I couldn't understand a thing!
难道我做错了什么？我应该在哪里保存我的文件？我尝试在 youtube 上观看教程，但大多数都是阿拉伯语，我什么都听不懂！
Thanks in advance for any help!
在此先感谢您的帮助！

Your JSP file must NOT be in WEB-INF.
您的 JSP 文件不能在 WEB-INF 中。
You must create a directory named as you want (myFirstWebAppfor example), put your JSP in any subdirectory you want except WEB-INF (for example myFirstWebApp/foo/bar/hello.jsp), then deploy the webapp by copying the myFirstWebApp firectory to the webappsdirectory of Tomcat. The JSP will then be accessible using the URL
您必须创建一个您想要命名的目录（myFirstWebApp例如），将您的 JSP 放在除 WEB-INF 之外的任何您想要的子目录中（例如myFirstWebApp/foo/bar/hello.jsp），然后通过将 myFirstWebApp firectory 复制到webappsTomcat 目录来部署 webapp 。然后可以使用 URL 访问 JSP
http://localhost:8089/myFirstWebApp/foo/bar/hello.jsp
WEB-INF is where you put the files that you don't want to make accessible from the outside:
WEB-INF 是您放置不想从外部访问的文件的地方：
- the jars (under
WEB-INF/lib), - the classes (under
WEB-INF/classes), - the deployment descriptor (web.xml, optional in servlet 3.0 webapps configured through annotations),
- and any other file you want anywhere under WEB-INF (typically, configuration files).
- 罐子（下
WEB-INF/lib）， - 课程（下
WEB-INF/classes）， - 部署描述符（web.xml，在通过注解配置的 servlet 3.0 webapps 中可选），
- 以及您想要的任何其他 WEB-INF 下的文件（通常是配置文件）。
Why don't you read the documentation? http://tomcat.apache.org/tomcat-7.0-doc/appdev/deployment.html
你为什么不阅读文档？http://tomcat.apache.org/tomcat-7.0-doc/appdev/deployment.html

Save your jsp file in your webapps directory with .jsp extention
将您的 jsp 文件保存在您的 webapps 目录中，扩展名为 .jsp
C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps and types at the address bar of the browser- http:\localhost:8089/exmp.jsp and press Enter key
C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps 并在浏览器的地址栏中键入- http:\localhost:8089/exmp.jsp 并按 Enter 键
