    How to implment polymorphism in JSF/Richfaces.

    ajaykumar kadiyala Novice

      I have one TopNavigation Interface

      TopNavigation.java

      interface  TopNavigation
      {
      public void newAction()
      {

      }
      public void viewAction()
      {

      }

      public void modifyAction()
      {

      }

      public void searchAction()
      {

      }

      public void saveAction() {

      }

      public void cancelAction()
      {

      }
      public void deleteAction()
      {

      }
      }
      ---------------------------------------------------------------------------
      1.a) Implementation Class
      public class PhoneTypesTopNavigationImpl implements TopNavigation
      {
      public void newAction()
      {
        // some logic
           return("-Phone-new-");
      }
      public void viewAction()
      {
        // some logic
           return("Phone-view-");
      }

      public void modifyAction()
      {
          // some logic
        return("Phone-modify-");
      }

      public void searchAction()
      {
          // some logic
        return("Phone-search-");

      }

      public void saveAction() {
          // some logic

        return("Phone-save-");

      }

      public void cancelAction()
      {
          // some logic

        return("Phone-cancel-");

      }
      public void deleteAction()
      {  // some logic

        return("Phone-delete-");

      }
      }

      1.b) Usage of implmentation class PhoneTypes
      public class PhoneTypes
      {
      public PhoneTypes()
      {
        TopNavigation ref= new PhoneTypesTopNavigationImpl();
        // Q1. I want to call the save when your clicked it's save button like ref.
        //Ex. ref.save(); How to get the reference in .xhtml file
      }
      }
      1.c)
      PhoneTypes.xtml

      <h:commandbutton action=#{ref.newAction()} />
      <h:commandbutton action=#{ref.viewAction()} />
      <h:commandbutton action=#{ref.modifyAction()} />
      <h:commandbutton action=#{ref.searchAction()} />
      <h:commandbutton action=#{ref.saveAction()} />
      <h:commandbutton action=#{ref.cancelAction()} />
      <h:commandbutton action=#{ref.deleteAction()} />

      2.a) Implementation Class
      public class CellTypesTopNavigationImpl implements TopNavigation
      {
      public void newAction()
      {// some logic
           return("-Cell-new-");
      }
      public void viewAction()
      {// some logic

           return("Cell-view-");
      }

      public void modifyAction()
      {// some logic
        return("Cell-modify-");
      }

      public void searchAction()
      {// some logic
        return("Cell-search-");

      }

      public void saveAction() {// some logic
        return("Cell-save-");

      }

      public void cancelAction()
      {// some logic
        return("Cell-cancel-");

      }
      public void deleteAction()
      {// some logic
        return("Cell-delete-");

      }
      }

      2.b) Usage of implmentation class CellTypes
      public class  CellTypes
      {
      public  CellTypes()
      {
        TopNavigation ref= new  CellTypesTopNavigationImpl();

      }
      }
      2.c) CellTypes.xtml //when user click on it's need call specify

      <h:commandbutton action=#{ref.newAction()} />
      <h:commandbutton action=#{ref.viewAction()} />
      <h:commandbutton action=#{ref.modifyAction()} />
      <h:commandbutton action=#{ref.searchAction()} />
      <h:commandbutton action=#{ref.saveAction()} />
      <h:commandbutton action=#{ref.cancelAction()} />
      <h:commandbutton action=#{ref.deleteAction()} />

      Q.2) Please sugest for face-config.xml as well

          Ilya Shaikovsky Master

          register both PhoneTypesTopNavigationImpl and CellTypesTopNavigationImpl as beans in faces config as usually.

           

          then using facelets:

           

          included page inlude.xhtml contains:

          ...
          <h:commandButton action="#{viewController.newAction}">
          ...
          

           

          first page which includes this include.xhtml

           

          <ui:include src="templates/includes/include.xhtml">
               <ui:param name="viewController" value="phoneTypesTopNavigationBean">
          <ui:include src="templates/includes/include.xhtml">
          

          second page which performs the same include but in the other context:

           

          <ui:include src="templates/includes/include.xhtml">
               <ui:param name="viewController" value="cellTypesTopNavigationBean">
          <ui:include src="templates/includes/include.xhtml">
          

           

          So you using different beans in the same include.

            Hi Ilya Shaikovsky ,

             

            Please help me the code for PhoneTypesTopNavigationImpl and PhoneTypesTopNavigationBean in face-config.xml as well PhoneTypesTopNavigationImpl.java and PhoneTypesTopNavigationBean.java.(Is it both are same PhoneTypesTopNavigationBean and PhoneTypesTopNavigationImpl).
