Subject [jira] Created: (HARMONY-6514) java.rmi.server.codebase
Date Wed, 19 May 2010 21:37:56 GMT
java.rmi.server.codebase
------------------------

                 Key: HARMONY-6514
                 URL: https://issues.apache.org/jira/browse/HARMONY-6514
             Project: Harmony
          Issue Type: Bug
          Components: JDK
    Affects Versions: 5.0M13
         Environment: ia32/linux
            Reporter: Kyle Cho
            Priority: Minor


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
string_s_print
