Inside <s:select>, the <s:options-collection> tag generates options
from the list of contacts obtained from
ContactListActionBean
. Notice that
you can use the
sort=
attribute to indicate the property by which to sort
the objects of the collection. We're sorting the contacts by their first
name.
A multiple-selection box acts much like a series of checkboxes that are
bound to a
Collection
property. In this case, the selected contacts are
bound to the
contacts
property of the
MessageComposeActionBean
class:
private
List<Contact> contacts;
public
List<Contact> getContacts() {
return
contacts;
}
public void
setContacts(List<Contact> contacts) {
this
.contacts = contacts;
}
Stripes automatically puts the selected contacts in the list so that we
can add them to the To, Cc, or Bcc field.

Image Buttons and Text Areas
Continuing with the Message Compose page, let's add the image but-
tons with arrows that are next to the contact list select box and add the
text area where the user can compose the text of the message.
Using Image Buttons
The <s:image> tag creates an image button that invokes the action
bean event handler indicated in the
name=
attribute.
