How to use checkbox in struts.

[Joey Watson]

Hello everybody.

I think this is a old question. but I can not find a good and complete
example in Google.
My question is :

I have a Jsp page which will list some datas for user. user can choose(by
click the checkbox) some of those data and click a botton for delete or some
others operator. So I think my Action class , ActionForm , data class and
JSP will like this.
----------------------------------------------------------------------
Row {
private String isSelect;
public getIsSelect() {
}
public setIsSelect() {
}
}
--------------------------------------------------------------------
ActionForm {

private ArrayList rows; //dynamic

public get....
public set...
}
---------------------------------------------------------------------
Action {
...
  for (int i = 0; i < ActionForm.rows.size; i++){
   Row row = ActionForm.rows.get(i);
   if ( row.isSelect =="check" ) {
     //Do some thing here.
   }
  }
}
....................................................................
JSP page.

I have to use <input type = "checkbox"> or <Html:Checkout> for data list.
datas quantity is not fix.
can not use <html:Mutibox>

and I need use a botton commit data to Action.
--------------------------------------------------------------------
my problem is :

1. In Row class. If define isSelect as a String , is it ok, or boolean is
better?
2. I don't know how to write <input type = "checkbox"> or <Html:Checkout> to
make a checkbox, and make action can know whick is be selected.

Thanks for any help.
