This program should send a text message from client to the server. i finished compiled the file. the server.java runs successfully but the client.java shows error.
the error list is too long so i only screenshot few lines.
this is the code
ReceiverMessageInterface.java
package com.mycompany.dsa3;
import java.rmi.*;
public interface ReceiveMessageInterface extends Remote{
void receiveMessage(String x) throws RemoteException;
}
RmiServer.java
package com.mycompany.dsa3;
import java.rmi.*;
import java.rmi.registry.*;
import java.rmi.server.*;
import java.net.*;
public class RmiServer extends
java.rmi.server.UnicastRemoteObject implements ReceiveMessageInterface{
String address;
Registry registry;
public void receiveMessage(String x) throws RemoteException{
System.out.println(x);
}
public RmiServer() throws RemoteException{
try{
address = (InetAddress.getLocalHost()).toString();
}
catch(Exception e){
System.out.println("can't get inet address.");
}
int port=3232;
System.out.println("this address=" + address + ",port=" + port);
try{
registry = LocateRegistry.createRegistry(port);
registry.rebind("rmiServer", this);
}
catch(RemoteException e){
System.out.println("remote exception"+ e);
}
}
static public void main(String args[]){
try{
RmiServer server = new RmiServer();
}
catch (Exception e){
e.printStackTrace();
System.exit(1);
}
}
}
RmiClient.java
package com.mycompany.dsa3;
import java.rmi.*;
import java.rmi.registry.*;
import java.net.*;
public class RmiClient{
static public void main(String args[]){
ReceiveMessageInterface rmiServer;
Registry registry;
String serverAddress=args[0];
String serverPort=args[1];
String text=args[2];
System.out.println ("sending " + text + " to " +serverAddress + ":" + serverPort);
try{
registry=LocateRegistry.getRegistry
(serverAddress,(new Integer(serverPort)).intValue());
rmiServer=(ReceiveMessageInterface)(registry.lookup("rmiServer"));
// call the remote method
rmiServer.receiveMessage(text);
}
catch(RemoteException e){
e.printStackTrace();
}
catch(NotBoundException e){
System.err.println(e);
}
}
}
please help me to correct the code. thanks
