Java.rmi.ConnectException: Connection refused to host: 10.41.8.140; nested exception is:
Agile:9.2.2.1
linux-x86_64
What is the Port in which you are ruinning the RMI?
You need to mention the port.
Simply chek if you have proper connectivity to the Server and the RMI Service as the speicifed port, try the debugging commands from command prompt like:
D:>telnet <Server IP Address> <Port Number>
If this command clears the windows into a blank window as if waiting for you input then it means that you have access to the Server and the RMI service is running on the machine.
If not, it is either NOT accessible or RMI Service is not working.
Thanks and regards,

What does java.rmi.ConnectException: Connection refused to host mean? ¶
Several users have run into a java.rmi.ConnectException message during deployment, and need some information on how to troubleshoot this. We'll be adding this to our documentation, but thought it might be useful now.
In NoSQL DB R2.0, the show plan -id <id> command displays plan status and any errors that may have occurred. If you see this exception listed in the error section, it means that the Admin service was unable to reach one of the NoSQL DB components while the system was trying to execute an administrative command.
The first step is check on the overall status of the store. One way to do that is to use the show topology command, followed by the verify command. The show topology command will display the layout of the store, while verify will check the status of each component. A component that can't be reached will display a status of UNREACHABLE.
In general, NoSQL DB attempts to make any troubleshooting information you need available through the Admin CLI, through commands like show plan, show events, show faults. A ConnectException message means that a communication channel either was not established, or failed, and in those cases, troubleshooting information may not have been conveyed to the Admin service. This is particularly true if there was a communication failure during initial deployment of a component.
The next step would be to look in the NoSQL log files for more detailed error information. Look first in the aggregated storewide log, which can be found in the node that is hosting the master admin service, under the KVROOT/<storename>/logs/<storename>*.log. You can locate the master Admin through the "verify" command. This log file contains information from all the different components in the store.
Suppose Replication Node rg1-rn3, on Storage Node sn3, is not responsive. Look through the <storename>.log for entries made by those components. Each log entry is prefixed with the name of the component that issued the log message. Sometimes the aggregated storewide log has too much information, or sometimes information from a component was not transmitted to the Admin, and therefore isn't included in the aggregated log. In that case, it can be more helpful to look at the Replication Node or Storage Node logs directly, which can be found on their host, in the <KVROOT>/<storename>/logs directory.
If the problem occurs during an initial deployment, it can be particularly helpful to review the Storage Node logs to make sure that the Storage Node Agent on that node was created correctly, and that the process came up as expected, according to the installation directions, and the Replication Node logs. Some of the common reasons why a Replication Node might not come up are that here is inadequate heap and memory on the node, or that a initial configuration parameter is misspelled or has an invalid value, or that the time skew between components is greater than NoSQL's acceptable limit.Several users have run into a java.rmi.ConnectException message during deployment, and need some information on how to troubleshoot this.

Java.rmi.ConnectException: Connection refuse
Hi all,
I have built a simple RMI client server application.I can run client & server fine locally.
However if I test this appplication over the internet, I get this exception on the client:
java.rmi.ConnectException: Connection refused to host: 169.254.157.53; nested exception is:
java.net.ConnectException: Connection timed out: connectConnection refused to host:169.254.157.53
The RMI server is running on my PC and the client on a friend's remote PC.Both PCs are connected to Internet.
I don't have any firewall running on my PC (including windows XP firewall). The server RMI lookup on the client happens correctly,
the exception is raised when the client tries to call the remote method on the server.
Here is an extract of my RMI server code (it works locally):
public static void main(String[] args) throws Exception {
try {
// args[0] contains the database server name given as command line argument, arg[1] contains binary path that contains weather jpeg files
CPrimaryWeatherServer test = new CPrimaryWeatherServer(args[0], args[1]);
Naming.rebind("rmi://localhost:1099/WeatherPrimaryService", test);
System.out.println("Serveur m�t�o principal d�marr�");
} catch (Exception e){ System.out.println(e.getMessage());}
Here is an extract of my RMI client code (it works locally):
try{
rec=1;
leftClik=1;
System.out.println("Before RMI lookup");
IPrimaryWeatherServerService serveur =(IPrimaryWeatherServerService)Naming.lookup("rmi://"+primWS+":1099/WeatherPrimaryService");
System.out.println("After RMI lookup");
System.out.println("Before server method call");
z=serveur.getFullWeatherData(); --> exception is raised here
System.out.println("After RMI server method call");
I am directly connected to Internet using an ethernet card connected to an ADSL modem.169.254.157.53 is the automatic IP of my network card different from the IP given by my ISP. By the way, the client tries to contact me using my DNS name that resolves correctly to my ISP IP adress.
Thanks a lot for help,because I am guessing that a local IP address is being embedded into the stub so the clien't can't find the remote server. I am guessing because you didn't provide the exception or its text. Anyway the suggestion will cause the correct public IP address/hostname to be embedded into the stub.

Java.rmi.ConnectionExceptionException:Connect refused to host
I write a rmi,when server and client runs in the same machine,it runs ok,then I run them in two machines,server runs in 192.168.0.1,like follows:
C:\>rmiregistry -J-Djava.security.policy=registerit.policy
C:\>java -Djava.rmi.dgc.leaseValue=1000 -Djava.security.policy=registery.policy RegisterIt
Object instantiated: HelloServer[RemoteStub [ref: [endpoint:[192.168.0.1:3120](l
ocal),objID:[0]]]]
and it ok ,client runs in 192.168.0.2, but it raise errors:
java -Djava.security.policy=registerit.policy HelloClient
HelloClient exception :java.rmi.ConnectionException:Connection refused to host:192.168.0.2;nested exception is:java.net.ConnectException:Connection refused:connect
Why? how to solve it?
Any idea will be appreciated!
My code is follows:
HelloInterface.java
public interface HelloInterface extends java.rmi.Remote{
public String sayHello() throws java.rmi.RemoteException;
HelloServer.java
import java.io.*;
import java.rmi.*;
import java.rmi.server.*;

System.out.println("Object instantiated: "+obj);
Naming.rebind("/HelloServer",obj);
System.out.println("HelloServer bound in registery");
catch(Exception e){
System.out.println(e);

System.out.println("null");
System.setSecurityManager(new RMISecurityManager());
try{
HelloInterface obj=(HelloInterface)Naming.lookup("/HelloServer");
String message=obj.sayHello();
System.out.println(message);
catch(Exception e){
System.out.println("HelloClient exception: "+e);
}Connection refused means the server is no listening on the port that client tried to connect to. You need to look at your configuration.

Exception in thread "main"
[b] Why does java system throws exception at invoke time not connection time at lookup time</b]
Any suggestion...
Regards,
Manoj> Are you getting this from a lookup()? If so it means the Registry you are looking for at rmi://x.x.x.x:5578 is not present.
I am getting it at the time when I invoke the method validate on the object returned from lookup.

looking for ur help
-shafeeqhi,
actually it is giving syntax error if i include like this in the client code
systemProperties.put("sun.rmi.transport.connectTimeout",15000);
systemProperties.put("sun.rmi.server.disableHttp","false");
pls guide me how exactly i should include in the client codings.
pls help
-shafeeq
Note: from http://java.sun.com/j2se/1.4/docs/guide/rmi/sunrmiproperties.html/#connectionTimeout
sun.rmi.transport.proxy.connectTimeout (1.1 and later)
The value of this property represents the maximum length of time (in milliseconds) that the RMI runtime will wait for a connection attempt (createSocket) to complete, before attempting to contact the server using HTTP. This property is only used when the http.proxyHost property is set and the value of java.rmi.server.disableHttp is false. The default value is 15000 milliseconds (15 seconds). -
Exception in the main client program: java.rmi.ConnectException: Connection
Hi
I have written a program in Java using RMI and it runs perfectly fine on my pc(localhost). But when I run it on the LAN in my office, the client program stucks and I get an exception
***Exception in the main client program: java.rmi.ConnectException: Connection refused to host***
***java.net.ConnectException: Connection timed out: connect***
Do we need to make some settings in the RMI server...or some firewall issue is there...By default port is 1099 as used by RMI registry server
Please help me TIA
vnx_inHi, i am having the same java.rmi.ConnectException, but the problem is that i can't even run it on localhost. I simply can't start my server, and i am getting a problem on Naming.rebind, however i think it could be because i am using an static ip to connect to internet in the LAN of my town. Does it matter in this case. I would be so thankful, because i am not able to solve it after many efforts.
Thanks in Advance :) -
Connection refused to host: connection timed out
I have been struggling with this problem a couple of days now so I really hope someone can help me. I am trying to get rmi to work in a NAT environment. We use a firewall, so I have opened port 1099 and 2020 which I use as a fixed port for communication (just to be sure it is not a firewall thing); I use the following code:

} catch (IOException e) {

null exited with code null.
I wonder how this could be happened?- It happens every single time the callback method is invoked, I see the event been deserialized client-side with the fields initialized with null values and server-side there is the java.rmi.ConnectException.
- The client can't unexport the callback object, that's because I didn't think to do it.
this is the method where I start to notify to all the registered client the event
for (ExitCodeCallback callbackElement : callback)
try
callbackElement.notifyExitCode(event);
catch (RemoteException ex)
logger.debug("Unable to notify.", ex);

java.net.ConnectException: Connection timed outfirst of all, which OS are you working on? This
question might sound wierd, but I have noticed a
lotta people working on Linux boxes havecomplained
about this. There is another mail thread about it:

http://forum.java.sun.com/thread.jspa?threadID=570065&
tstart=0
is your client able to look up the reference tothe
server ? If so, can you print that reference andfind
out which port the remote server is listening on ?
here did u mean Naming.LookUp("rmi://10.1.129.3") in the client.thats where i get connection refused while doing naming.lookup.
Then use the netstat command to see if the serveris
indeed listenign on that port when the connectionis
refused !
netstat -anp - p | grep <port_of_server>
let me know how it goes.
when i did netstat -anp - p | grep <port_of_server> on my client this is what i get ...

ConnectException, connection refused
I have an RMI server/client Web applet program working, with the server running on a RHEL4 linux server, and other linux clients.
When I try to run the applet from a browser on a Windows client, I get a connection refused error. I am not setting a security manager,
and both boxes are using Java 1.6.07. The exception and its stack trace are as follows:

Any ideas?Never mind... had edited code and somehow had a Naming.lookup instead of using the object returned by LocateRegistry.getRegistry(URL).
I'm on to the debugging of the access denied issue now...
Sorry, I'm a newbie but I'm learning fast. -
RMI Callback Connection Refused Problem
we are running Red Hat Linux 9, we previously had a problem connecting a server and client running in 2 different PC's. we had the following error
Exception in mainjava.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is:
java.net.ConnectException: Connection refused
we used the -Djava.rmi.server.hostname= <hostname> option to make it run. Now, were trying to make use of call backs this time we ran into another problem having the error:
Exception in mainjava.rmi.ConnectException: Connection refused to host: 172.16.100.24; nested exception is:
java.net.ConnectException: Connection refused
what are we doing wrong?We already included a security manager. but the error is still there.
