Hey everyone,
I;ve implemented SSL to my server using this guide

now when I connect the server it takes some time to initialize now, I assume its setting up stuff, and then when the client connects takes awhile as well (few seconds), I'd assume it works but I want to see a log or something where client and server create the handshake, any ideas how? The way that I start my server is:

java -Djavax.net.ssl.keyStore=keystore -Djavax.net.ssl.keyStorePassword=password HelloImpl &

What I tried was to use:

System.setProperty("javafx.net.ssl.keyStore","C:\\Users\\Slavi\\workspace\\rmiSSL\\keystore");
System.setProperty("javafx.net.ssl.keyStorePassword","password");

and then start the server using
-Djavax.net.ssl.debug=all -cp . HelloImpl > 1.txt HelloImpl &
by doing so it prints out a lot of information in a file but at the end I don't see the things that my server is supposed to return when its up and running such as "Server running"

then I commented out the setProperty lines and tried started the server using
java -Djavax.net.ssl.keyStore=keystore -Djavax.net.ssl.keyStorePassword=password -Djavax.net.ssl.debug=all -cp . HelloImpl > 1.txt HelloImpl &
and then in my text file I only get "Server running" and no information about the handshake after a client connets or what so ever. Although when I run a client, everything seems pretty smooth, and I get the expected result on client side

Any ideas? :x

Ummmm I tried implementing SSL on the big project now but .. omg the errors I get ....

This is how it is implemented on the server side

        super(0, new SslRMIClientSocketFactory(), new SslRMIServerSocketFactory());
                                System.setProperty("javafx.net.ssl.keyStore","C:\\Users\\Slavi\\workspace\\PrintServer\\src\\server\\keystore.jks");
        System.setProperty("javafx.net.ssl.keyStorePassword","password");

and this is the Client side

System.setProperty("javafx.net.ssl.truststore","C:\\Users\\Slavi\\workspace\\PrintServer\\src\\application\\truststore.jks");
        System.setProperty("javafx.net.ssl.trustStorePassword","trustword");

when the client tries to communicate, these are the errors I get ...

I am really stuck with this trying to implement it ... I am back to hello world application ... It runs perfectly fine if called from Terminal, completley goes nuts if called from Eclipse ......

Here is the entire code that I am using ...

RMI Interface:

import java.rmi.Remote;
import java.rmi.RemoteException;


public interface Hello extends Remote {
    public String sayHello() throws RemoteException;
}

RMI Server

import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
import java.rmi.server.UnicastRemoteObject;
import javax.rmi.ssl.SslRMIClientSocketFactory;
import javax.rmi.ssl.SslRMIServerSocketFactory;

public class HelloImpl extends UnicastRemoteObject implements Hello {
    public HelloImpl() throws RemoteException {
        super(0, new SslRMIClientSocketFactory(), new SslRMIServerSocketFactory());
        LocateRegistry.createRegistry(3000);
        System.out.println("RMI registry running on port 3000");
    }
    public String sayHello() {
        return "Hello World!";
    }
    public static void main(String args[]) throws Exception {
        System.setProperty("javafx.net.ssl.keyStore","C:\\Users\\Slavi\\workspace\\rmiSSL\\keystore");
        System.setProperty("javafx.net.ssl.keyStorePassword","password");
        // Get reference to the RMI registry running on port 3000 in the local host
        Registry registry = LocateRegistry.getRegistry(null, 3000);
        // Bind this object instance to the name "HelloServer"
        HelloImpl obj = new HelloImpl();
        registry.bind("HelloServer", obj);
        System.out.println("HelloServer bound in registry");
    }
}

RMI Client

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

public class HelloClient {
    public static void main(String args[]) throws Exception {
        System.setProperty("javafx.net.ssl.trustStore","C:\\Users\\Slavi\\workspace\\rmiSSL\\truststore");
        System.setProperty("javafx.net.ssl.trustStorePassword","trustword");
        // Get reference to the RMI registry running on port 3000 in the local host
        Registry registry = LocateRegistry.getRegistry(null, 3000);
        // Lookup the remote reference bound to the name "HelloServer"
        Hello obj = (Hello) registry.lookup("HelloServer");
        String message = obj.sayHello();
        System.out.println(message);
    }
}

if I run the server using:
java -Djavax.net.ssl.keyStore=keystore - Djavax.net.ssl.keyStorePassword=password server/RmiServer

and the client
java -Djavax.net.ssl.trustStore=truststore -Djavax.net.ssl.trustStorePassword=trustword HelloClient

everything works fine but if I just run the server and the client instead of
System.setProperty(.....) to set the keystore and the trustStore I get these errors:

C:\Users\Slavi\workspace\rmiSSL>java HelloClient

Any help/ideas more than welcome ...

I think the problem comes from this line
super(0, new SslRMIClientSocketFactory(), new SslRMIServerSocketFactory());
I set the system properties after this line but I think they should be before otherwise the keyStore used is something default but I can't call super unless on the same line, perhaps I should create new instance of the remote server after system props are set?

PS: there was a type in the original version I had "javafx." instead of "javax."

That might be the reason; you can simply use a static block in the class to load/call stuff at the time class is loaded. Though I think setting this in code is the wrong approach and the correct way would be to handle these things when deploying your code (for e.g. in the startup script/bat file/shell script which spawns the server and client).

That was the reason ,works like a charm now :)
