Struts 多行提交及操作
UserInfo　bean 相关属性
public class UserInfo{

private String username;
private String password;

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}
}


单个的UserInfo

public class UserInfoForm extends ActionForm {

private static final long serialVersionUID = 1L;
private String username;
private String password;

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}
}

多个的UserInfo
public class UserInfoListForm extends ActionForm{

private static final long serialVersionUID = 5049729273082639532L;
private List users=new AutoArrayList(UserInfoForm.class);

public List getUsers() {
return users;
}

public void setUsers(List users) {
this.users = users;
}
}


public class AutoArrayList extends ArrayList{

private static final long serialVersionUID = 7329071318112930773L;
private Class itemClass;

public AutoArrayList(Class itemClass) {
this.itemClass = itemClass;
}

public Object get(int index) {

try {
while (index > = size()) {
add( itemClass.newInstance());
}
} catch (Exception e) {
e.printStackTrace();
}
return super.get(index);
}
}


添加操作的ＪＳＰ页面
<html:form action= "/userInfo ">
用户名１： <html:text property= "users[0].username "/> <br>
密　码２： <html:text property= "users[0].password "/> <br>

用户名２： <html:text property= "users[1].username "/> <br>
密　码２： <html:text property= "users[1].password "/> <br>
<html:submit/>
<html:form>

在添加操作中的action 的处理将users列表转换为每一个的UserInfoForm再赋给
UserInfo　bean中来保存

读取操作的ＪＳＰ页面
<html:form action= "/userInfo ">
<logic:iterate id= "user " name= "userInfoListForm " property= "users ">
<html:text property= "username "/> <br>
<html:text property= "password "/> <br>
</logic:iterate>
<html:submit/>
</html:form>

想请问下我这样做是否合理，再来怎样来进行修改（初学者）．
如果我使用表格来动态的添加或者册除相应的一组UserInfoForm时，
这时修改操作又该如何进行处理


[解决办法]
private String username;
private String password;
直接设为数组就可以了

private String[] usernames;
private String[] passwords;


用户名１： <html:text property= "usernames "/> <br>
密　码２： <html:text property= "passwords "/> <br>


[解决办法]
lz代码中的users[0]和users[1]是什么?
