HI,
I hope this code clears your doubt
public class HelloDyn extends PageProcessorComponent {
  public DynPage getPage(){
    return new HelloDynDynPage();
  public static class HelloDynDynPage extends JSPDynPage{
    public int state = 0;
    public void doInitialization(){
    public void doProcessAfterInput() throws PageException {
     public void confirm(Event event) {
          IPortalComponentResponse response=(IPortalComponentResponse)this.getResponse();
          IPortalComponentRequest request =(IPortalComponentRequest)this.getRequest();
          InputField inputf=(InputField)getComponentByName("name");
          String inputValue=inputf.getValueAsDataType().toString();
          response.write("Welcome" + " "+inputValue);
          IUser user1 = request.getUser();
          String usn = user1.getDisplayName();
          response.write(usn);
          state = 1;
    public void doProcessBeforeOutput() throws PageException {
         switch(state)
              case 0:
               this.setJspName("HelloJsp.jsp");
               break;
               case 1:
               this.setJspName("hiUser.jsp");
               break;
