Description

It seems -Djava.rmi.server.codebase property not to work. Below are Si.java, S.java. and C.java to reproduce problem.

---------Si.java-------
import java.rmi.Remote;
import java.rmi.RemoteException;

public interface Si extends Remote {
public String s_print() throws RemoteException;
}

---------S.java--------
import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
import java.rmi.server.UnicastRemoteObject;

public class S implements Si {
public String s_print() throws RemoteException

{ return "string_s_print"; }

public static void main(String[] args) throws Exception

{ String s1 = "S_Print"; S s = new S(); Si stub = (Si) UnicastRemoteObject.exportObject(s, 0); Registry registry = LocateRegistry.getRegistry(); registry.rebind(s1, stub); }

}

---------C.java--------
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;

public class C {
public static void main(String[] args) throws Exception

{ String s = "S_Print"; Registry registry = LocateRegistry.getRegistry(); System.out.println(((Si)(registry.lookup("S_Print"))).s_print()); }

}

1. Create stub.jar which contains Si.class and put it to /tmp/.
2. Run following commands.
(terminal 1)$ drlvm/deploy/jdk/jre/bin/java org.apache.harmony.rmi.registry.RegistryImpl
(terminal 2)$ drlvm/deploy/jdk/jre/bin/java -Djava.rmi.server.codebase=file:/tmp/stub.jar S
(terminal 3)$ drlvm/deploy/jdk/jre/bin/java C

From terminal 1, following exception will be thrown.

Running the same test with IBM or SUN jdk 1.5 prints expected output as below.

(terminal 1)$ rmiregistry
(terminal 2)$ java -Djava.rmi.server.codebase=file:/tmp/stub.jar S
(terminal 3)$ java C
