it fixes the issue Polymorphism is not inherently dependent on inheritance.
Polymorphism is a rather abstract concept about giving uniformous interfaces to different kinds of values.

hop of those help? First and foremost you should pick up a good C++ book and read the concepts:

JPA Inheritance and EJB polymorphism

JPA Inheritance and EJB polymorphism

Does that help This is an EJB Polymorfism, and can be applied to other situations. It doesn't relate to JPA inheritance directly.
The trick is to use @Local interface for EJBs:
code :
public interface MyClassFacadeInterface {    
    public void doSomething(MyClass c);
public void doSomething() {      
    for (MyClass c : myClassFacade.findAll()) {      
        String lookupName = getNameFromClassName(c.getClass().name());
        MyClassFacadeInterface myInt =  (MyClassFacadeInterface) new InitialContex().lookup(lookupName);

Any of those help You're putting methods inside of methods and in fact you've got your main method enclosing all of the code of your Bicycle class -- don't do this. Your main method should be its own separate method, should not hold other methods, should create a Bicycle instance. call methods on this instance and that's about it.
code :
public class Bicycle {
        public int cadence;
        public int gear;
        public int speed;

    public Bicycle(int startCadence, int startSpeed, int startGear) {
        gear = startGear;
        cadence = startCadence;
        speed = startSpeed;

    public void setCadence(int newValue) {
        cadence = newValue;

    public void setGear(int newValue) {
        gear = newValue;

    public void applyBrake(int decrement) {
        speed -= decrement;

    public void speedUp(int increment) {
        speed += increment;

    public void printDescription() {
    System.out.println("\nBike is " + "in gear " + this.gear
        + " with a cadence of " + this.cadence +
        " and travelling at a speed of " + this.speed + ". ");

    public static void main(String[] args) {
      Bicycle bicycle = new Bicycle(20, 10, 2);
      // ... etc

it fixes the issue C++ is usually very strict on this type of inheritance, if you'd like a work around you could use this to solve issues like this d1.f(); :
code :
class Base
    virtual void f(int i) { printf("Base::f(int)"); }

around this issue You have a misunderstanding of what you should be doing in inheritance. extends is a reserved word that was wisely chosen. The point of B extending A is to say that B is a subset of A with additional attributes. You're not supposed to redefine x in B; A should be handling x. By redefining x in a subclass, you're hiding the superclass' field x (this is true even if x refers to different variable types).
