I have been following this step by step tutorial about RMI : http://www.javacamp.org/moreclasses/rmi/rmi.html

and already succeeded in compiling and run this project by using command prompt as what the tutorial has taught here : http://www.javacamp.org/moreclasses/rmi/rmi6.html

But now i am wondering, how is it if i want to create this project using Netbeans? so that i can create GUI for this project and just run it from the Netbeans IDE. Up until now, i have tried the multiple numbers of way to create it on Netbeans, but each time, the project failed to be run. please help, as i have spent about 4 days already and not yet find any solution or tutorial that can guide me through.

this is the screenshot that i got after trying to run it from Netbeans :

error

thanks in advanced!

p/s : to be clear, what i am trying to do is "to create a swing client for the RMI application that create and run the RMI invocation in Netbeans instead of commandline "

Define 'failed to be run'. State why you are following a third-party tutorial in preference to the one provided with the JDK. – EJP Jun 13 at 11:40

What have you tried? Do you mean you want to create a swing client or run the RMI invocation in Netbeans instead of commandline? – Nazar Annagurban Jun 13 at 11:43
whenever i tried to run the server from the netbeans, theres an error like "Server exception thrown: java.rmi.ConnectException: Connection refused to host:" . and the reason i am using the third-party tutorial is because that is the only tutorial that i have found so far that is works and i never found the one that is provided with the jdk like what you are talking about. where could i find it? thanks. – ryzalyusoff Jun 13 at 11:53

It's the 'only tutorial you have found that works' and it doesn't work? – EJP Jun 13 at 11:55
oh no, what i mean is that it works when i run it using the command line, but it failed when i tried to recreate the project and run it from the Netbeans IDE. – ryzalyusoff Jun 13 at 11:59

actually, you can use both LocateRegistry.createRegistry() or just type rmiregistry in the command prompt to start the rmiregistry whenever u want to use it for netbeans project

I have finally found the way to do this. What i need to do is start the RMIRegistry first before i run the Server. Unlike in the command prompt where i have to typr "start rmiregistry", i just have to put this line in my Server.java code in the Netbeans to start thr RMIregistry : " LocateRegistry.createRegistry(1099);" where 1099 being the port number.

'Connection refused' means in this case that there was no Registry running at the indicate IP:port. So fix that, or fix the IP:port.

oh. i thought that if we run our project from Netbeans, it will start the RMIRegistry for us. could you give me reference on how to start the regitry from netbeans? thanks! – ryzalyusoff Jun 13 at 12:14

Why? In production, you need to either start the rmiregistry command, or use LocateRegistry.createRegistry() from within. Why do it differently when testing? – EJP Jun 14 at 4:16
