Hello,
Is it possible to have multiple server implementation of the same remote
interface i.e.
public interface A extends javax.ejb.EJBObject {
public void doSomething (...);
}
public interface AHome extends javax.ejb.EJBHome {
public A createForPurpose (purpose Purpose);
}
and, on the server side :
public abstract class ABasicBean implements javax.ejb.EntityBean {
public String name;
...
} // not used....
public class ASuperBean extends ABasicBean {
public String superIdea;
...
} // used
public class ASuperBisBean extends ABasicBean {
public String superIdeaBis;
...
} // parallel and used
public class AMegaBean extends ASuperBean {
public String anotherSuperIdea;
...
} // below super and used
In the createForPurpose method (where should it go? in which class?), the
choice would be done accordingly to the given parameter (enumeration). What
about the persistance?
Any comment? (I plan to use JBoss if some "interpretation" of the spec is
needed)
More generally, you may have some idea or pattern for my problem. I want to
have, on the server side, several class (each extending the same root) and
linked to a CMP entity bean. I do not want to use serialized dependant class
because these classes may (and will) contain some logic which should not be
made available to the client. On the other hand, the available classes
should be quite easily extendable.
Any idea? cheers,
Sacha
