Help with RMI university assignment

Question

Hi everybody,
The assignment asks for the definition of three remote interfaces ICompany, IProject and IStaff, define one 1:M relationship (ICompany -> IProject) and print on the console the company together with the projects they have placed. There is no requirement for a DB therefore i've create a method on the server
populateDummyDB(ProjectImpl proj)that fills a Vector with projects with their coresponding company ID's.
I've also created a company instance on the server which i successfully print on the client by callingprintCompany(Object obj) but i need help with theprintProjects() so that as soon the company is printed it searches the Vector for projects that have the same companyID matches the PK with the FK and print those projects.
Any help will be more than welcome.

Thanks for the reply and sorry for the vagueness.
The company is created and bound to RMI on the Server
CompanyImpl myCom = new CompanyImpl("101234", "WH Smith",
                    "Nick Parks", null);
myCom.bindToRMI("com1"); also on the Server the Vector that is defined in the ProjectImpl.java is populated
public static void populateDummyDB(ProjectImpl proj)
            throws RemoteException {
        proj.addProject(new ProjectImpl("Project A", "10 Feb 2005", 11000,
                "101234", null, null));
        proj.addProject(new ProjectImpl("Project B", "16 Feb 2005", 8700,
                "178745", null, null));
        proj.addProject(new ProjectImpl("Project C", "19 Feb 2005", 17400,
                "130928", null, null));
        proj.addProject(new ProjectImpl("Project D", "27 Feb 2005", 12800,
                "178745", null, null));
        proj.addProject(new ProjectImpl("Project E", "04 Mar 2005", 9760,
                "101234", null, null));
        proj.addProject(new ProjectImpl("Project F", "09 Mar 2005", 5340,
                "178745", null, null));
        proj.addProject(new ProjectImpl("Project G", "13 Mar 2005", 15290,
                "101234", null, null));
        proj.addProject(new ProjectImpl("Project H", "17 Mar 2005", 5780,
                "101234", null, null));
        proj.addProject(new ProjectImpl("Project I", "23 Mar 2005", 20100,
                "130928", null, null));
        proj.addProject(new ProjectImpl("Project J", "30 Mar 2005", 6780,
                "130928", null, null));
} The company is printed successfully on the Client
public class HKClientView{
    public static void main(String[] args) {
        HKClientView cmdUI = new HKClientView();
    public static final String SERVER_NAME = "localhost";
    public HKClientView() {
        ICompany yourCom = getRemoteCompany();
        try {
            CompanyTO yourComData = yourCom.getCompanyData();
            printCompany(yourComData);
//            printProjects();
        } catch (RemoteException re) {
            System.out.println("Exception thrown while creating company "
                    + "instance! " + re);
    private ICompany getRemoteCompany() {
        ICompany myCompany = null;
        ProjectImpl myProject = null;
        try {
            myCompany = (ICompany) Naming.lookup("//" + SERVER_NAME + "/com1");
        } catch (Exception e) {
            System.out.println("Exception thrown while creating company "
                    + "instance! " + e);
        return myCompany;
    private void printCompany(Object obj) {
        System.out.println(obj.toString());
} If you look closely at my dummy DB table four out of the ten projects belong to the company that i've created since the have common companyID = "101234". How can i get those projects printed on the Client?
