java

package cn.itcast.action;

import java.awt.List;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.sun.javafx.collections.MappingChange.Map;

public class LoginAction extends ActionSupport {
private String username;

private String password;
private String sum;
private String test;
protected List data=new List();
public String login() throws Exception {

sum=username+password;
ServletActionContext.getRequest().setAttribute("message",sum);
data.add(username);
data.add(password);
data.add(sum);
data.add(test);
ServletActionContext.getRequest().setAttribute("data",data);
return "failer";
}

public String getUsername() {    
    return username;
}    
public void setUsername(String username) {    
    this.username= username;
} 
public String getPassword() {    
    return password;
}    
public void setPassword(String password) {    
    this.password= password;
} 
public void setTest(String test) {    
    this.test= test;
} 
public String getTest() {    
    return test;
}   

}

我想想吧，看能不能做出来这个。

页面是个怎样的，不能显示

大兄弟。。你包都引错了，，

data定义成public的，然后设置data的get和set方法再去页面上看看
