在这个例子中，我们将创建一个简单的动态Web应用程序，使用JavaServer Pages (JSP)，Struts框架，以及Apache Tomcat服务器。以下是构建此示例的步骤：
步骤1：环境准备
确保已安装以下软件：
- Java Development Kit (JDK)
- Apache Ant (用于编译和构建项目)
- Apache Tomcat服务器
步骤2：创建项目结构
在你的工作目录中创建以下目录结构：
```
MyWebApp/
-- WebContent/
-- index.jsp
-- src/
-- com/
-- myapp/
-- actions/
-- MyAction.java
-- beans/
-- User.java
-- utils/
-- UserManager.java
-- build.xml
-- web.xml
```
步骤3：编写代码
`User.java` (在`src/com/myapp/beans`目录下)
```java
package com.myapp.beans;
public class User {
private String name;
private String email;
// Getters and Setters
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
```
`MyAction.java` (在`src/com/myapp/actions`目录下)
```java
package com.myapp.actions;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
public class MyAction extends org.apache.struts.action.Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
User user = (User) form;
UserManager um = new UserManager();
um.saveUser(user);
request.setAttribute("
