Hi, I am running RMI on Apache Server. The server I am running RMI on is Windows NT and it had dynamic IP. It used to work absolutely perfect. But now we changed our network and that server has got a static IP but now since then I am not able to run RMI on that server. As and when I try to login using RMI..It gives the following error messages. ************Error Message***************** java.rmi.ConnectException: Connection refused to host: pratik; nested exception is: java.net.ConnectException: Connection refused: connect java.net.ConnectException: Connection refused: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.Socket.<init>(Unknown Source) at java.net.Socket.<init>(Unknown Source) at sun.net.NetworkClient.doConnect(Unknown Source) at sun.net.www.http.HttpClient.openServer(Unknown Source) at sun.net.www.http.HttpClient.openServer(Unknown Source) at sun.net.www.http.HttpClient.<init>(Unknown Source) at sun.net.www.http.HttpClient.<init>(Unknown Source) at sun.net.www.http.HttpClient.New(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.connect(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getOutputStream(Unknown S ource) at sun.rmi.transport.proxy.HttpSendSocket.writeNotify(Unknown Source) at sun.rmi.transport.proxy.HttpSendSocket.<init>(Unknown Source) at sun.rmi.transport.proxy.RMIHttpToCGISocketFactory.createSocket(Unknow n Source) at sun.rmi.transport.tcp.TCPEndpoint.newSocket(Unknown Source) at sun.rmi.transport.tcp.TCPChannel.createConnection(Unknown Source) at sun.rmi.transport.tcp.TCPChannel.newConnection(Unknown Source) at sun.rmi.server.UnicastRef.newCall(Unknown Source) at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source) at java.rmi.Naming.lookup(Unknown Source) at chat.ChatClient.<init>(ChatClient.java:51) at GUI.Interface.<init>(Interface.java:331) at Collaborator.main(Collaborator.java:174)

Hi Pratik, Here is what happens : when the RMI client wants to fetch the class definition of the stub from the Apache server, the connection to the Apache server fails. Possible reasons : 1- DNS problem : the host name pratik cannot be resolved to the IP address of the Apache server --->replace the name pratik by the actual IP of Apache server 2- The Apache server is not running or is running at a port different from 80 ----> try : telnet apache_server_ip 80 3- either 1 or 2 Regards
