public
Contact getContact() {
if
(contactId !=
null

contactDao.read(contactId);

public void

.contact = contact;
}
}
The code in the
ContactFormActionBean
class is now lean and mean:
package
stripesbook.action;
public class
ContactFormActionBean
extends
ContactBaseActionBean {
private static final
String FORM="/WEB-INF/jsp/contact_form.jsp";
@DefaultHandler
Ê
public
Resolution form() {
return new
ForwardResolution(FORM);
}
Ë
public
Resolution save() {
Contact contact = getContact();
getContactDao().save(contact);
getContext().getMessages().add(
new
SimpleMessage("{0} has been saved.", contact)
);
return new
RedirectResolution(ContactListActionBean.
class
);
}
Ì
public
Resolution cancel() {
getContext().getMessages().add(
new
SimpleMessage("Action cancelled.")
);
return new
RedirectResolution(ContactListActionBean.
class
);
}
}
The default event handler at
Ê
forwards to
contact_form.jsp
. When the
user clicks the
Save
button,
save
( ) is called (
Ë
) and uses the DAO to
save the contact. It then adds an information message to the list and
redirects to
ContactListActionBean
, which displays the messages and the
table of contacts. The event handler for the
Cancel
button (
Ì
) just adds
an information message and redirects to the contact list without saving
the contact.
