求大神帮忙看看，新手，不是很明白，代码：
index.jsp
<body>
<form action="user.action">
<h3>请输入要查询的id:<input name="id"/></h3>
<input type="submit" value="提交"/>
</form>
</body>

public class User extends ActionSupport {
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String toString() {
return "id = "+ id +", name = "+ name;
}
}
