can you have a composition in an ActionForm ?

Hi there,

I wonder if it's to create a form bean with composition. I mean, assuming I have the following 2 classes:
AccountInformation ( fname, lname...)
CreditCard (number, type...)

I would like to know if I can create a form, registration, that is composed from AccountInformation and CreditCard???

it will look like this:
class Regitration
AccountInfomration accountInfo;
CreditCard creditCard;

So...
1. is it possible to do that?
2. if yes, how would the registration.jsp page will look like?

If it was a regular form, it would have been:

<td>
<fmt:message key="register.creditcard.number"/>
</td>

<td>
<html:text property="ccNumber"
size="30"
maxlength="30" />
<html:errors property="ccNumber" />
</td>

what comes in the property (i tought creditCard.number but that doesn't work)

thanks for any advise.

The "property" attribute in your <html:text... tag will try to map to a getter method within your form called getCcNumber().

The following should get you what you're looking for:

Code:

...
<td>
    <html:text property="ccNumber"
...

in the form class...

public String getCcNumber() {
     return creditCard.number;
}

public void setCcNumber(String ccNumber) {
      this.creditCard.number = ccNumber;
}

As long as your getter and setter methods are named correctly, you should be able to use any type of composite class for your form.

p.s. If getCcNumber() doesn't work, try getccNumber(). There is a definite syntax for getter/setter capitalization.
