Hello friends, Any idea why do I get RemoteException while trying to invoke methods on Unix machine from Windows. I am inside the network and dont think this is because of firewall problem as I can do "telnet" from Windows to Unix box after starting the RMI server at the unix box. I also could not understand why is it going to local loo...
I've followed the instructions in the following link to create my own RMI registry and jmx server on a single port inside tomcat. According to the comments, I need to set -Djava.rmi.server.hostname=localhost. Once I do that, I can indeed connect to my server via jconsole using ssh port forwarding. http://blogs.sun.com/jmxetc/entry/con...

I'm having huge performance issues when I add RMI proxy references to a Java Swing JList-component. I'm retrieving a list of user Profiles with RMI from a server. The retrieval itself takes just a second or so, so that's acceptable under the circumstances. However, when I try to add these proxies to a JList, with the help of a custom L...
Hi Everyone, This may seem like a very broad question, but any help is appreciated. I have a client/server solution written in java which uses the Cajo project (which uses RMI). I just want to try and make my solution as secure as possible, given the sensitive data that will be transferred between server and client. So far, my ideas a...

Hello! I have a general question concerning client-server design. We have a Java server with Spring, a GWT client program and some HTTP-servlets for our site. At the moment we also want to develop an applet which would communicate with that server in such a way GWT-client and site requests do. Is it a good idea to communicate with the...

I think I need to connect to a remote RMI object without going through the registry, but I don't know how. My situation is this: I'm implementing a simple job distribution service which consists of one distributor and multiple workers. The distributor has a registered RMI object to which clients connect to send jobs, and workers connec...

I want to set up a firewall in the server machine but I don't know which port I shou...
I'm building a Monopoly game in Java and I want it to be able to support games over the net (the point was so me and my friends over in the US of A could play). Networking is a whole area of programming I have yet to enter so I have been finding it quite hard to decide how exactly to pull it off. In general, I felt that the correct way ...
I'm having trouble finding a clear answer to this question so I thought I'd ask here with my own specific example: I am creating a mulitplayer monopoly game. The actual monopoly code runs on the server and the client is essentially a GUI which accesses and control this code. The monopoly game is controlled by a class called 'Bank'. Sa...

Example: public interface IRobotController { public int walk(int meters); public void dance(int seconds); } public interface RMIRobotController imp...
