Eclipse – Failed to connect to remote VM. Connection refused. while tring to debug jar

I have concentrated on junit instead of tomcat as it is much quicker & easier to reproduce. Yep I had seen the McQueeney link with no luck.

We have done some more digging and interestingly when you run junit from Eclipse, Eclipse decides to go & check for updates, Yes that's right - everytime you run a junit (& I guess tomcat and others).

We removed a colleague's access restrictions to the WWW through the ISA server and low & behold the problem disappeared.

We are still monitoring this to see if it is the solution. Watch this space.

I have tried looking through the Eclipse set up to see if I can stop it trundling off everytime to the WWW but have not seen a suitable option yet.

I think your server is down and that's why you receive a connection refused. I don't see your server.accept() call that makes server socket wait for new clients to come and returns a Socket object not SocketServer.

I have done this code for you. I hope it helps.

            BufferedReader in = new BufferedReader(new InputStreamReader(
                    insocket.getInputStream()));
            PrintWriter out = new PrintWriter(insocket.getOutputStream(),
                    true);
            String instring = in.readLine();
            out.println("The server got this: " + instring.toUpperCase());
            insocket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
