import mydomain.users;

public class usersDAO {

public List<users> getUsers() {

List<users> allUsers = new ArrayList<users>();

users u1 = new users();
u1.setUserName("John");
u1.setUserCode("User101");
u1.setUserPassword("xxxxx");
u1.setFirstName("JohnFirstName");
u1.setLastName("JohnLastName");
u1.setHomePhone("1111111111");
u1.setMobilePhone("222222");
u1.setActive("Y");
allUsers.add(u1);

u1 = new users();
u1.setUserName("Robert");
u1.setUserCode("User102");
u1.setUserPassword("xxxxx");
u1.setActive("Y");
u1.setFirstName("RobertFirstName");
u1.setLastName("RobertLastName");
u1.setHomePhone("53534343");
u1.setMobilePhone("4534343");
allUsers.add(u1);

u1 = new users();
u1.setUserName("Sean");
u1.setUserCode("User105");
u1.setUserPassword("xxxxx");
u1.setFirstName("SeanFirstName");
u1.setLastName("SeanLastName");
u1.setHomePhone("1111111111");

u1.setHomePhone("53534343");
u1.setMobilePhone("4534343");
allUsers.add(u1);

return allUsers;
}

}


DemoVM.java


package mydomainUI;

import java.util.ArrayList;
import java.util.List;
import org.zkoss.bind.annotation.Init;

import domainDAO.usersDAO;
import mydomain.users;

public class DemoVM {

private List<users> allUsers = new ArrayList<users>();

public List<users> getAllUsers() {
return allUsers;
}

public void setAllUsers(List<users> allUsers) {
this.allUsers = allUsers;
}


@Init
public void initSetup() {
// Load the department first
allUsers = new usersDAO().getUsers();

}

}


Now you can run demo.zul. The output as follows
