Hi, please help me i am stuck due to this error at client side, i have also included the policy file at the build folder but still not solving any problem for me. Change the IP address 192.168.1.102 to your IP address. Better not to use localhost 10 Run your server but for the sake only of compiling through clicking the Green play button shown below: 11 Now, You need to open your DOS cmd console ( or unix terminal). Navigate to your workspace BIN folder for the project. The location of your project can be known through clicking: Select the project ChatServer, Right Click -> Properties 12 Copy the location shown on the next window for the project: 13 Within the CMD black window, type in the full location of the bin folder. Rmic ChatClient -> Press Enter That’s for the Client now. I use Netbeans 6 (java 6) for all of my coding. I'm hoping someone here could give me a run down on how to get an RMI project up and running through Netbeans. To be specific, I'd like to be able to see the examples from HF Design Patterns & HF Java run on my computer. Aug 15, 2012 While working on my assignment for the Sun Certified Developer for the Java 2 Platform certification, I discovered that little documentation exists for setting up a simple Remote Method Invocation (RMI) hello world application using Netbeans. 3) Packaging of the Applications 1 Copy the stub file for the server side ChatServer_stub.class to the src folder of the client as shown below: 2 Copy the stub file for the client side ChatClient_stub.class to the src folder of the server as shown below: 3 Right click on the project ChatServer, select Refresh: 4 Do the same for the ChatClientProj project, Right click and select Refresh 5 Right Click on the project ChatServer, select Export 6 Select Java –> Runnable Jar file 7 on the next screen, Select ChatServer – StartServer for the launch Configuration. Browse for a place to save your exported jar file and click Finish, you can name it as server.jar 8 Do the same for the ChatClientProj and export it as client.jar 4) Running the Server & Client 1 The server can be run from Eclipse, or you can use the Server.jar file to run it from any PC through the command (CMD console). I am trying to make a very simple chat program using RMI ( no GUI's) but i am struggling for ideas. How do i register clients when they connect to the server? When i use RemoteServer.getClientHost() all this does is show the ip address (and they are the same for all clients that connect from the same computer (from multiple command windows). What i am trying to implement is this: when a client logs on he is shown a switch-case menu and ift they press • they get a list of connected clients. • sendMessage(client, String) But i do not know how to identify individual clients?
