getting formbean properties in Action class

[Thomas Thomas <de...@gmail.com>]

Hi,

To get the properties these two ways work :

1) System.out.println("lastName   = " + custForm.get("login"));

2) System.out.println("lastName   = " + request.getParameter("login"));

Why should I use 1) rather than 2) ?

Thank u.

At that level there really isn't an advantage.  The advantage comes in when
you use Struts' abiltity to traverse nested beans.  In other words if you
create an ActionForm that has some bean attributes you Struts will manage
all that complexity for you.  Maybe an example:

public class DateBean {
  private int day;
  private int month;
  private int year

    // assume there are accessors and mutators for each of the attributes
  }

--=< From Struts Config >=--
<form-bean name="MyForm" type="com.vsp.canada.controller.DynaForm">
  <form-property name="date" type="DateBean" initial="0"/>
</form-bean>

--=< From the JSP >=--

<html:text property="date.day" size="2" maxlength="2"/>
<html:text property="date.month" size="2" maxlength="2"/>
<html:text property="date.year" size="4" maxlength="4"/>

--=< From your Action >=--
DynaActionForm data = (DynaActionForm)form;
DateBean = ((DateBean)data.get("date"))

Using this you can have the three form fields in the JSP handled as a single
object in Java.

Hi,

I use the property utils,

PropertyUtils.getSimpleProperty(aForm, "exchange");

PropertyUtils.seetSimpleProperty(aForm, "exchange","NASDAQ");

Thanks,

Nuwan.
