How does a remote client get a CMR reference

[Jingyi Wang]

Suppose I have two beans: Movie and Director
In bean Movie, I have virtual CMRs:

public abstract Director getDirector ();
public abstract void setDirector ( Director d );

I also need a business method getMovieDirector () to get
a given movie's director, IMPORTANT HERE, the client is a remote client, how can I deal with it. In P386, there is a method like

public Director getMovieDirector () {
return getDirector ();
}

but the Director has to reference a local reference. I need a method like:

DirectorRemote getMovieDirector ();
How can I deal with that, or I am in total wrong way here.

Thanks

You can not get the cmr field through the remote interface, but you can define a value bean and create a method to retrieve the cmr-field and populate the value bean with cmr-field's value, then return the value bean.

Just another flavour to Jason's comment...

In movie's remote interface declare a method

DirectorRemote getMovieRemoteDirector() throws RemoteException;

In movie bean implement this method:

 
// biz interface method
public DirectorRemote getMovieRemoteDirector() {
  // Director has to have getID() method
  <DirectorPKType> id = getDirector().getID(); 

  javax.naming.Context ic = null;
  try {
    ic = new InitialContext();
    DirectorRemoteHome dirHome = 
      PortableRemoteObject.narrow(
        ic.lookup("java:comp/env/ejb/remote/Director"), 
        DirectorRemoteHome.class);
    
     return dirHome.findByPrimaryKey(id);  
   }
   catch (FinderException e) {
        throw new EJBException(e);  
   }
   catch (NamingException e) { 
throw new EJBException(e);   
   }
   catch (RemoteException e) {
throw new EJBException(e);   
   }
   finally {
try {
  if (ic != null) { ic.close(); }
}
catch (javax.naming.NamingException e) {
throw new EJBException(e);
}
   }
}

Thank you both very much. I got it.
