其实我只是刚看了这很老的东西，为了加强一下记忆，这种方法是比较原始了，你还可以使用Struts标签，呵呵！在开发中，建议使用Struts标签。
public class User {
private String name;
private int age;
private String sex;
private String profile;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getProfile() {
return profile;
}
public void setProfile(String profile) {
this.profile = profile;
}
}
public class out extends ActionSupport{
private String name;
private User user;
public String print(){
System.out.println("user.Name="+user.getName());
System.out.println("user.Sex="+user.getSex());
System.out.println("user.Profile="+user.getProfile());
this.addFieldError("name", user.getName());
return "pas";
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}在这里我采用了绝对路径，其实我个人觉得如果你对路劲不是很熟悉的话就用绝对路劲，对页面中“<base href="<%=basePath%>">“和“String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
”我就不多做解释了，加上他们就可以使用绝对路径了。
<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
