Hi Friends,
This might be vendor specific question but I am posting it to the list
because I am not able to figure out whether the problem is only with
weblogic or some other app server also.
EJB guru's can just have look at the code and can comment on this...
My problem is that when I am trying to generate container for CMP it is
giving following error
"In EJB Product, the home interface must define the findByPrimaryKey
method."
But findByPrimaryKey is there in home interface , it is taking primary key
class as argument and returning remote interface and is public.
If I make the same as BMP it is saying that
"In EJB Product, the find method
findByPrimaryKey(ejb.entity.cmp.product.ProductPK) did not have a
corresponding ejbFind method in the bean class."
Here is my source .....
-----------------------------------------------------------------
package ejb.entity.cmp.product;
import javax.ejb.*;
import java.rmi.RemoteException;
import java.util.Enumeration;
public interface ProductHome extends EJBHome {
public Product create(String productID, String name, String description,
double basePrice) throws CreateException, RemoteException;
public Product findByPrimaryKey(ProductPK key) throws FinderException,
RemoteException;
//public Enumeration findByName(String name) throws FinderException,
RemoteException;
// public Enumeration findByDescription(String description) throws
FinderException, RemoteException;
// public Enumeration findByBasePrice(double basePrice) throws
FinderException, RemoteException;

FinderException, RemoteException;
// public Enumeration findCheapProducts(double maxPrice) throws
FinderException, RemoteException;

RemoteException;
