Connection Refused To Host Nested Exception Is Java.net.connectexception Connection Refused Connect
down vote favorite 1 I'm working on a RMI command-line game but, whenever I try to my Service, I receive an error like this: java.rmi.ConnectException: Connection refused to host: 192.168.56.1; nested exception is: java.net.ConnectException: Connection timed out: connect This is the main class for my Server: public class RMIWar { public static void main(String[] args) throws RemoteException, MalformedURLException { try { Controle obj = new Controle(4); Registry reg = LocateRegistry.createRegistry(1099); connection refused to host: 127.0.1.1; nested exception is: System.out.println("Server is ready"); reg.rebind("CtrlServ", obj); } catch (Exception e) { System.out.println("Error: " + e.toString()); } } } The main for my Client class: public class RMIWarClient { public static void main(String[] args) throws RemoteException, MalformedURLException, NotBoundException { try { Registry registry = LocateRegistry.getRegistry("localhost"); ControleInt ctrl = (ControleInt) registry.lookup("CtrlServ"); System.out.println("CtrlServ found...\n"); BioRMI bio = new BioRMI(null, 5,5,5); ctrl.thRegister("Test", bio.atk, bio.def, bio.agi); } catch (Exception e) { System.out.println("Error: " + e); } } } Any suggestions? java exception java-ee rmi share|improve this question edited Dec 13 '11 at 7:51 Alberto Solano 5,12231941 asked Dec 13 '11 at 6:29 Samuel 1302413 add a comment| 4 Answers 4 active oldest votes up vote 10 down vote accepted Test if your 1099 port is available. Also, you didn't mentioned what OS you are using and if you started the registry before the execution of your server. This RMI tutorial explains: Before starting the compute engine, you need to start the RMI registry. The RMI registry is a simple server-side bootstrap naming facility that enables remote clients to obtain a reference to an initial remote object. By default, the registry runs on port 1099, like yours. As the tutorial reports, just open a command prompt (on Windows) or a shell terminal (on a

Start Rmi Registry
on my glassfish server and tens of clients for it, invoking the business
Java.rmi.connectexception Connection Refused To Host Jmeter
method poll() of this bean. The code is like this: @Stateless public class EntryPort implements EntryRemote { public void java.rmi.server.hostname example poll( String payload ) { try { Registry registry = LocateRegistry.getRegistry( "localhost", 0 ); IStubIn stub = (IStubIn)registry.lookup( "ejb/ExitPortBean" ); Message msg = new Message(); msg.getBody().setContent( payload ); stub.pushRead( msg ); }catch ( http://stackoverflow.com/questions/8485239/java-rmi-connect-exception-connection-refused-to-host-timeout Exception e ) { } } } Please, note that the poll() method makes a lookup for a remote object exported to the RMI Registry and so invokes the pushRead() method on it. This method is synchronized due to concurrent access. Sometimes in my server log I see exceptions like this: java.rmi.ConnectException: Connection refused to host: 192.168.1.128; nested exception is: java.net.ConnectException: Connection refused: connect They https://coderanch.com/t/487650/java/java/java-rmi-ConnectException-Connection-refused are raised by this method execution. I have already set in the java.security file the following properties but the problems carries on. networkaddress.cache.ttl=0 networkaddress.cache.negative.ttl=0 Any advices/tips? Thanks, Rafael. Nitesh Kant Bartender Posts: 1638 I like... posted 6 years ago What is the relation b/w connection refused and the network address cache settings? The IP shown in the connect exception is the IP of your server? Does your RMI server crash in between? apigee, a better way to API! Rafael Z. Frantz Greenhorn Posts: 20 posted 6 years ago Hi Nitesh, The IP is the IP of my local machine at home. It is strange, because sometimes I this message, with different IPs or even the localhost address, like this: java.rmi.ConnectException: Connection refused to host: 192.168.1.128; nested exception is: java.net.ConnectException: Connection refused: connect java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is: java.net.ConnectException: Connection refused: connect java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: java.net.ConnectException: Connection refused: connect All these errors at the same execution for the same code. And besides,, in different lines each time: @Stateless public class EntryPort implements EntryRemote { public void poll( String payload ) { t
Protege client-server tutorial. This page is being updated as issues arise. Contents 1 Basics 2 Versioning http://protegewiki.stanford.edu/wiki/Troubleshooting_Client_Server_Connections Problems and UnmarshalExceptions 3 RMI Registry Synchronization 4 Java https://support.ptc.com/apps/solution_preview/solution/lang/presolution?lang=en&n=CS59006 1.6.0_29 and 1.7 rmiregistry issue 5 Networks, Firewalls and Telnet 5.1 Configuration 6 See Also Basics In troubleshooting, it is very useful to understand that the client will first connect to the rmi registry to get a reference connection refused to the server and then will use the server reference to contact the server. This protocol is discussed here (ignore the black magic tricks unless they help you get a better understanding). The first thing to do is to look at any messages on the client and connection refused to server console. The most fundamental error that can arise is the following exception which appears on the client console: SEVERE: java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: java.net.ConnectException: Connection refused at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:574) at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:185) at sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:171) at sun.rmi.server.UnicastRef.newCall(UnicastRef.java:306) at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source) at java.rmi.Naming.lookup(Naming.java:84) at edu.stanford.smi.protege.server.ServerPanel.connectToHost(ServerPanel.java:140) Note that the exception happens when trying to call Naming.lookup. Usually the client will pop up a window that says Unable to Connect to Server. This means that the client could not connect to the rmiregistry. Possibly the rmiregistry is not running or there is a firewall or other network problem. An alternate very different error that appears on the client console is the following exception SEVERE: java.rmi.ConnectException: Connection refused to host: 67.180.198.51; nested exception is: java.net.ConnectException: Connection timed out at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:574) at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:185) at sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:171) at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:94) at edu.stanford.smi.protege.server.Server_Stub.openSession(Unknown Source) at edu.stanford.smi.protege.server.ServerPanel.createSession(S
