Hi James,

Sure, here is my CorbaRemoteStreamExporter class:

import java.rmi.RemoteException;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.rmi.PortableRemoteObject;
import javax.rmi.CORBA.Stub;
import org.omg.CORBA.ORB;
import com.healthmarketscience.rmiio.RemoteStreamServer;
import com.healthmarketscience.rmiio.exporter.RemoteStreamExporter;
 
public class CorbaRemoteStreamExporter extends RemoteStreamExporter {
 
	@Override
	protected Object exportImpl(RemoteStreamServer<?, ?> remoteStreamServer) throws RemoteException {
		PortableRemoteObject.exportObject(remoteStreamServer);
		Stub stub = (Stub)PortableRemoteObject.toStub(remoteStreamServer);
		
		try {
			Context context = new InitialContext();
			ORB orb = (ORB)context.lookup("java:comp/ORB");
			stub.connect(orb);
		}
		catch (NamingException exception) {
			// TODO: handle exception
		}
		
		return lStub;
	}
 
	@Override
	protected void unexportImpl(RemoteStreamServer<?, ?> remoteStreamServer) throws Exception {
		PortableRemoteObject.unexportObject(remoteStreamServer);
	}
}

As for the example that confused me - it is the very first one entitled "The 'server' is reading a file from the 'client'". Instead of calling a method and passing the RemoteInputStream I return it as part of my method call and as such I shouldn't perform the close.

 

 

[Question Removed]

-- Sorry, I made a stupid mistake. This question wasn't really relevant.

By the way James, thanks for all your help and for making RMIIO publicly available.

 

 

right, because in your case: the 'client' is reading a file from the 'server'. maybe i should put more examples in which cover more use cases.

 

 

I think that would be useful. Perhaps a few dealing directly with EJBs and sending a file to and receiving a file from a Remote interface? Feel free to include "my" CorbaRemoteStreamExporter anywhere it might be useful.

 

 

already added a reference to your exporter in the FAQ section for app servers. i also added a another example of the "server" returning a remoteinputstream to the "client" which hopefully spells out the stream management a little more clearly.

 

 

Hi jtahlborn, I have followed your sample exporter codes, however, it throws below exception:

I'm running IBM Rational Software Architect v 7.0.0.2.

Any idea?

Thanks

 

 

glassfish uses dynamic stub generation, so the exporter alone will be sufficient. however, you must be using a platform which expects statically generated stubs. you should checkout the RMI IIOP Guide as well as the example corba code in the RMIIO project (which may include the necessary stubs already).
