The Add View.
Controllers
Now that you have an idea as to what the site is going to look like, let's add the functionality
to actually make it work. Your first steps in doing this are adding the necessary
Service
classes
that include your business logic. You will add three services. Each of these classes will imple-
ment the
Service
interface. The following sections describe each of these classes and where
they fit into your Web application.
The
LDAPDirectory
Service
The
LDAPDirectory
class, like all other service classes in your server-side model, implements
the
Service
interface. The implemented
execute()
method is where all of its major function-
ality exists. It starts its execution when a user selects the
Directory
link in the
navigation.jsp
. When its execution starts it uses the
LDAPManager
to perform a wildcard
search for all
People
objects in the
virtuas.com
domain. The resulting
LDAPObject
s are then
added to the
request
object and forwarded to the named target, which in this case is the previ-
ously listed
directory.jsp
. The source for
LDAPDirectory
is in Listing 21.6.
