Listing 14: Implementation for

getUsers()

/** Add the getUsers method to the implementation */

public class UserManagementBean implements SessionBean {

public Collection getUsers(){

ArrayList userList = new ArrayList(50);

Collection collection = userHome.findAll();

Iterator iterator = collection.iterator();

while(iterator.hasNext()){

LocalUser user = (LocalUser)iterator.next();

userList.add(user.getEmail());

}

return userList;

}

Using the

getUsers()

public class Section2Client {

methods from the client

public static void main(String[] args) {

The client code invokes the

getUsers()

method.

Collection collection

It

=

then

userMgmt.getUsers();

takes the collection of emails that uniquely

Iterator iterator = collection.iterator();

identify a user returned from the

getUsers()

while(iterator.hasNext()){

method and prints them out to standard out.

String email = (String)iterator.next();

System.out.println("user id=" + email);

}

}

}

Compiling and deploying the

findAll()

EJB QL

example

The same technique can be used to the build, package, and deploy the findAll example

as was used to build, package, and deploy the first example which can be found at the

on page panel. All of the source and build file for this example can be found at

cmpCmr/section2.2

.
