推荐答案

创建java web应用程序的步骤：

1.创建新的动态网络项目

2.将现有servlet文件复制到src文件夹

3.在WebContent / WEB-INF文件夹中创建 web.xml 文件

4.配置 web.xml ，例如：

Steps to create java web application:
1.Create new Dynamic Web Project
2.Copy existing servlet file to src folder
3.Create web.xml file in WebContent/WEB-INF folder
4.Configure web.xml, for example:

<?xml version="1.0" encoding="UTF-8"?>
<web-app 
        xmlns="http://java.sun.ru/xml/ns/javaee" 
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xsi:schemaLocation="http://java.sun.ru/xml/ns/javaee http://java.sun.ru/xml/ns/javaee/web-app_2_5.xsd" 
        version="2.5">
 <servlet>
    <servlet-name>hello</servlet-name>
    <servlet-class>test.HelloServlet</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>hello</servlet-name>
    <url-pattern>/hello</url-pattern>
  </servlet-mapping>
</web-app>

使用您的servlet类替换 test.HelloServlet ，servlet名称也可以替换

5.在Eclipse中打开服务器视图，使用上下文菜单添加新的Tomcat服务器，发布项目并运行服务器。

replace test.HelloServlet by your servlet class, servlet name also may be replaced
5.Open Server view in Eclipse, add new Tomcat Server using context menu, publish the project and run server.
