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_in

Hi, 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 :)

    Regards,

    > 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.

  • 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.

  • 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.

    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.

    first of all, which OS are you working on? This

    about this. There is another mail thread about it:
    >

    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 ...

  • Java Virtual Machine Launcher could not find the main class - program will

    I have installed J2SE and followed all the instructions but upon restarting the PC I get a dialogue box with the messege Java Virtual Machine Launcher could not find the main class - program will exit.
    I have tried multiple times un-installing and re-intalling this but i still get the messege when i restart windows.
    Can anyone offer any suggestions as to what i may be doing wrong.
    When I do the verify installation I get the congtratulations you have the latest Java Installed.
    Help

    Something is being automatically started when the pc starts. Assuming Windows, to see what it is, learn to use the msconfig program:

    Apparently, whatever it is, it's not correctly configured.

  • Execute jar file: "could not find the main class" program will terminate

    Hey,
    I am new to Java. I have started to make a small java program which supposed to help me at my studies to lean the Dominic Memory System. I have used the latest version of Netbeans 5.5.1 to build my program in. I have two problems which I cannot figure out how to solve, please help me.
    The first problem is that the java script I have made works when I compile it in Netbeans, but when I create a Jar file it does not work. I receive a pop up message in windows ?could not find the main class program will terminate? when I execute the jar file.
    The second problem I have is that I need to compare the strings generated by the "numbers" and "TIP" and if the numbers is not identical the numbers in the ?Center? JPanel should be highlighted as red.
    If anyone would like to clean up the code I would be pleased. I have copied quite a lot from anyone because of my one lack of knowledge.

  • Java.rmi.ConnectException using webstart Swing client with WL 8.1 SP2 in a

    Hi all,
    I'm receiving the following exception when invoking a remote method on

  • Error msg Could not find the main class.Program will exit. in jar execution

    Hello,
    I have created a jar so that I can used it in the webapp.
    but when I click on it it says "Could not find the main class.Program will exit."
    I searched a lot in the net and found that it has to do with the manifest file.
    I even updated the manifest file using the command "jar umf main.txt filefolderupload.jar" with the class name mention along with the package heirarchy.
    (pakage heirarchy in /,\ and .)
    I am using JDK 1.5 . and have Updated JRE 1.6.
    Also tried with extending the class with JApplet, but in vain.
    Kindly help me in the above mention issue.

    This post hints at a number of misunderstandings on your part, and raises a couple of important questions.
    Note that this 'simple question' has a complicated answer. Given the complexity of it, it might pay to add Dukes to it, ..a lot of Dukes.
    The important questions are.
    1) Does this file/directory uploader need to provide the end-user with a file dialog in which they can choose a local directory to upload, or will a multi-file chooser do?
    2) Does this uploader need to upload to foreign sites, or does it upload back to its own server?
    Looking at this table I prepared to describe the [uploader/local file access|http://pscode.org/test/uploader/fileuploader.html] possibilities, if the answers to the questions are 'multi-file chooser will do' and 'home site only', the best option is a sandboxed app. launched using webstart (JNLP) - option 5. If either of those questions go the other way, option 6 (digitally signed with extended permissions) is needed.

    Connection refused means the server is no listening on the port that client tried to connect to. You need to look at your configuration.
