Error while deploying CMP.. can u pls tell me...

Question

Hi,
Below is the error my jboss 3.2.3 container is throwing when i tried to deploy my CMP entity bean. It says
my ejbFindByPrimaryKey() method must be implemented,but in a CMP i am told the container will take care of the implementation, one just has to specify it in the home object.. can anyone pls tell me where i could have gone wrong.

This is my code
ProductBean
import javax.ejb.EntityContext;
import javax.ejb.EntityBean;
public abstract class ProductBean implements EntityBean {
     protected EntityContext ctx;
     //All set and get Methods
     public abstract String getName();
     public abstract void setName(String name);
     public abstract String getDescription() ;
     public abstract void setDescription(String desc);
     public abstract double getBasePrice() ;
     public abstract void setBasePrice(double baseprice);
     public abstract String getProductID();     
     public abstract void setProductID(String prodname);
     //EJB required Methods
     public void ejbActivate(){
          System.out.println("ejbActivate called");
     public void ejbRemove(){
          System.out.println("ejbRemove called");
     public void ejbPassivate(){
          System.out.println("ejbPassivate called");
     public void ejbLoad(){
          System.out.println("ejbLoad called");
     public void ejbStore(){
          System.out.println("ejbStore called");
     public void setEntityContext(EntityContext ctx){
          System.out.println("setEntityContext called");
          this.ctx=ctx;
     public void UnsetEntityContext(){
          System.out.println("UnsetEntityContext called");
          this.ctx=null;
     public void ejbPostCreate(String productID,String name,String description,double basePrice){
          System.out.println("ejbPostCreate called");
     public ProductKey ejbCreate(String productID,String name,String description,double basePrice){
          System.out.println("Create method  called");
          setProductID(productID);
          setName(name);
          setDescription(description);
          setBasePrice(basePrice);
          return new ProductKey(productID); // i am not sure which to retun,
          //return null;
                                           //Well just on a note for the above
                                          // I READ THAT CMP2.0 MUST RETURN NULL, BUT IN ED-ROMANS MASTERING
                                          // EJB  IT SAYS THE BEAN MUST RETURN THE PRIMARY KEY CLASS.
                                          // I HAVE TRIED BOTH THE ABOVE RETURN VALUES, STILL I GET THE SAME
                                          / /ERROR.

ProductKey class - This is my PRIMARY KEY CLASS
