Eclipse & Running my RMI Server

I have everything set up nicely to run my RMI Sever from eclipse and I keep getting this error message. Any help would be greatly appreciated:
Exception in MAIN java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
     java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
     java.lang.ClassNotFoundException: com.ibm.SvcCliSimulator.RMIRemoteMethod_Stub
The stub is in the same dir. as the RMIServer class. I know my code is fine b/c when I do it with JDK by hand it works just fine, but I'd like to keep it in my ECLIPSE development environment. HELP

OK, a bit more information. I know that Eclipse is FINDING the actual class file, because if I comment out everything in the stub then I get this different error:
Exception in MAIN java.rmi.StubNotFoundException: Stub class not found: com.ibm.SvcCliSimulator.RMIRemoteMethod_Stub; nested exception is:
     java.lang.ClassNotFoundException: com.ibm.SvcCliSimulator.RMIRemoteMethod_Stub
Same sort of deal, but different none the less. I've searched everywhere, but I can't get any help:
public static void main(String[] args) {
          try{
               RMIRemoteMethod m = new RMIRemoteMethod();
               Naming.rebind("test", m);
               System.out.println("RMIServer READY");
          catch(RemoteException re){
               System.out.println("Exception in MAIN " + re);
          catch(Exception e){
               System.out.println("Exception: " + e);
The exception occures on the Naming line if my stub is set up correctly and on the line before if I camment out the entire stub.java file. Any help would be really really great. Thanks.

  • How do I make a RMI client running in Bea find a remote, non Bea, RMI server?

    On my stand alone test system I run a RMI server in one JVM,
    registry.exe and a RMI client in its own JVM. The client uses
    java.rmi.Naming.lookup() to find the RMI server, and this works fine.
    If I run the same RMI client class within Bea the naming lookup fails! I
    guess this is due to Bea using it own RMI registry rather than the
    registry.exe I started separately(?)
    QUESTION: How do I make a RMI client running in Bea find a remote,
    non-Bea, RMI server?
    Of course, in the final environment the server will run on a system
    remote from Bea.
    The RMI client calls are done from a servlet, not from a EJB.
    The doumentation about using RMI with Bea is focused on running the RMI
    server within Bea. This might be the "normal" thing to do, but in our
    case Bea is the client, not the server. Do I still need to use
    weblogic.rmi.*....? If so, where?
    Grateful for any tip.

  • RMI server behind firewall--must use host as name, not IP

    Server is running behind a firewall, which runs such that any machine behind the firewall cannot use the external IP to get back to itself.
    That is:
    - outside IP = 192.171.20.5 (port forwards 1099 to 192.168.1.5:1099)
    - inside IP = 192.168.1.5 (rmi server listens on 1099)
    from the machine inside (192.168.1.5), it is IMPOSSIBLE to create a socket to [outside ip](192.171.20.5), port 1099, and expect it to get back to the machine inside--the firewall prohibits this.
    I -can- use name-based lookups, such that I can edit the hosts file on the inside box to route (myhost.com to 192.168.1.5). So, if everyone's DNS resolves myhost.com -> 192.171.20.5, then clients anywhere can go to myhost.com:1099 and will be redirected to my internal machine (192.168.1.5:1099).
    The problem with this is that the names get translated to IPs and sent back to the client.
    Is there a way to keep the names as names, so that both client (using external real-world DNS entries) and server (using local hosts file) can both resolve to the proper IP addresses?
    I'm starting server, as follows:
    java -Djava.rmi.server.codebase=http://myhost.com/rmi/ -Djava.security.policy=/policypath/policy -Djava.rmi.server.hostname=myhost.com mypkg.myclass
    The client connects and gets this message (from a connection exception):
    java.rmi.ConnectException: Connection refused to host: 192.168.1.5;

    Server is running behind a firewall, which runs such
    that any machine behind the firewall cannot use the
    external IP to get back to itself.I dont really understand this statement.. Machines behind the firewall referring to the external ip would be going to the gateway, not themselves.. Or do you have an internal AND external ip on the machines behind the firewall? Or are we referring to the gateway machine as an internal machine as well as external?
    That is:
    - outside IP = 192.171.20.5 (port forwards 1099 to
    192.168.1.5:1099)
    - inside IP = 192.168.1.5 (rmi server listens on
    1099)looks good, what kinda OS/firewall? If we're talking linux/ipchains (or iptables) with ip masquerading, I may be of some use to you...
    from the machine inside (192.168.1.5), it is
    IMPOSSIBLE to create a socket to [outside
    ip](192.171.20.5), port 1099, and expect it to get
    back to the machine inside--the firewall prohibits
    this.If you're on the internal network, why can't you just go for the internal ip addr? If I'm understanding correctly, you want internal dns requests for myhost.com to resolve to 192.168.1.5, and external dns requests to resolve to 192.171.20.5? That should't be a problem...
    I -can- use name-based lookups, such that I can edit
    the hosts file on the inside box to route (myhost.com
    to 192.168.1.5). So, if everyone's DNS resolves
    myhost.com -> 192.171.20.5, then clients anywhere can
    go to myhost.com:1099 and will be redirected to my
    internal machine (192.168.1.5:1099).the hosts file has nothing to do with routing, it's simply a dns-type thing... If your dns is giving external users a 192.168 address as the ip for myhost.com, they will never get to it. 192.168 is not routable on the internet, i think most inet routes will drop packets from 192.168.x.x or 10.x.x.x.
    Is there a way to keep the names as names, so that
    both client (using external real-world DNS entries)
    and server (using local hosts file) can both resolve
    to the proper IP addresses?As long as your dns is working correctly, java doesn't care if you use ips or host names.. Hostnames are preferable, so when you change your network around, you wont affect your rmi server.
    I'm starting server, as follows:
    java -Djava.rmi.server.codebase=http://myhost.com/rmi/
    -Djava.security.policy=/policypath/policy
    -Djava.rmi.server.hostname=myhost.com mypkg.myclass
    The client connects and gets this message (from a
    connection exception):
    java.rmi.ConnectException: Connection refused to host:
    192.168.1.5;Is your server compiled with the 192.171 ip? That's not gonna work, you have to use the same IP the server is running on. I'm still not clear on your network layout, is 192.171.20.5 and 192.168.1.5 the 2 gateway ip's, or is 192.168.1.5 a physically different machine? I'd be willing to bet that your server is compiled with the external address, and if that's not the same machine, then there's no chance of that working....
    There's more than port forwarding going on.. IIRC, java rmi keeps track of its own ip's.. A client request to an external ip will not connect to a server running on the internal ip, even if you forward the port, rmi itself doesn't recognize the internal as the ip it's trying to get to (even if it is true), so it bombs out.. This can happen if you run the rmi server on a gateway, and compile the server with the external ip, and try to connect to the internal ip.. If you want external machines to connect, you MUST run the server on an external ip.
    Give a little more info, we'll getcha running... I'm also assuming you have full control of your network (ie, firewall/dns)

    pub.interfaces.ClientIface is in the SAME directory as the RMI server class! What could be causing this?
    NOTE: I'm running this on Redhat Linux 9, jdk 1.5.0_04.

    Usually an unmarshalling exception is caused by the classes not matching up on the server & client end. The classes are there I think, because otherwise it would have thrown a classnotfound exception instead. Can you try actually copying and pasting the classes either from the server to the client or vice versa? I've had weird issues where sometimes the compiler compiles the same class differently in different locations, so your safest bet is to make sure the client & server classes (that you're passing as arguments & returning from the server) are identical.
    Good luck!

  • Java.rmi.server.hostname

    Hi,
    i am trying to figure out where this property comes into play. The docs say:
    "The value of this property represents the host name string that should be associated with remote stubs for locally created remote objects, in order to allow clients to invoke methods on the remote object. In 1.1.7 and later, the default value of this property is the IP address of the local host, in "dotted-quad" format."
    So i reverse engineered the stub to see if the value is inside the stub, but it isnt. I am asking because i want to run my RMI server program as a service and i dont want to define a static hostname property, because the server can be installed on several machines. Perhaps i can leave out this property completey and rely on defaults.
    So two questions remain to me:
    - Can i leave out this without getting into trouble?
    - Where is this propery used, obviously not in the stub.
    Thanks.
    marc

    Hi Marc,
    - Can i leave out this without getting into trouble?
    Possibly, see answer to your second question.
    - Where is this propery used, obviously not in the stub?
    The property is used primarily for one of two reasons, otherwise it is generally not necessary.
    1. If you have more than one network interface on a given machine, this property will specify which one to use.
    2. If you are behind a NAT router, this property will specify the actual address to use, outside the NAT subnet.
    Unspecified it will use the default network adapter address specified by your OS.
    Hope that was interesting :-)

  • Not able to run a simple RMI server

    I am running an RMI program like follwing
    import java.rmi.* ;

    Add the classes (the stubs included) to the classpath when you start the registry.

  • Codebase run RMI server .NoClassDefFoundError:

    If I run the folllowing from the solaris command line
    java -cp /junk/jdev+/jdev/src -Djava.rmi.server.logCalls=true -Djava.rmi.server.codebase=file:////junk/jdev+/jdev/src/ -Djava.security.policy=/junk/jdev+/jdev/src/jdev/server/policy jdev.server.RMIServerDBAdapter
    my RMIServerDBAdapter binds regardless of my current working directory. In other words the RMI server
    runs and binds as expected.
    If I remove the classpath clause of the java command (-cp /junk/jdev+/jdev/src) then the RMI server
    will only run and bind if my current working directory is the "root" of the package.
    In this case if my current working directory is /junk/jdev+/jdev/src the RMI server will run and bind as
    it should. If my current working directory is at the root of the solaris file system ( / ) I get the following error
    Exception in thread "main" java.lang.NoClassDefFoundError: jdev/server/RMIServerDBAdapter
    My question is why doesn't the code base clause of the java command point to the root
    directory of the package /junk/jdev+/jdev/src. It seems to me that the codebase clause
    would point to the root directory of the package allowing the RMI server to run and bind as expected
    regardless of the current working directory.
    I cannot get this to work. I have tried 0-4 slashes (file:/, - file:////) that did not seem to help.
    The package statement in the java source files is
    package jdev.server
    Thank you in advance for your help.

    Hi Ciaccio,
    Your question is doesn't clear enogh to me to answer it straight... But I'll try... :)
    First you must not mix the reason and usage of the codebase and classpath. Classpath is locally parsed and used, codebase is remotely parsed and used (at the registry and at the client side).
    Your server program cannot start if you don't tell to the system where to find the needed classes. That's why you have to specify the root path of the jdev.server.RMIServerDBAdapter in the CLASSPATH (from that point will search the java system the jdev dir, the server dir and the RMIServerDBAdapter object) .
    If the Java system is unable to locate any of a needed class it throws a nice exception during the startup of the server program.
    The codebase property is used by the client and the registry to locate the stub objects (and return types and parameter types) if those cannot be found on their local classpath. This path (or it would be more accurate to call what it is: URL) must be an absolute address (path, URI, etc), because the clients and the registry can be started anywhere. This way you also have to set RMISecurityManager and polici files also to your client because of dynamic class downloading...
    Last thing:
    Note the line above: ...if those cannot be found on their local classpath... If the stubs and the param/return types are present in the registry's and the clients local classpath then you don't have to specify codebase property at the server side because it is not parsed at all.
    I hope I could help,
    Sanyi

    The Java� Tutorial - Trail: RMI

  • Urgent Help Required For Starting RMI server from servlet.

    I am currently working on rmi project.
    I want to send request to remote machine(Web host) where my application is from desktop client .For that we are using RMI.
    I am writing servlet and inside it i am binding object to registry for rmi server.
    which will be deployed on remote server.
    code ....
    Registry reg;
    reg=LocateRegistry.createRegistry(1099);
    Server server=new Server("server");//class whose remote object to be accessed
    //extends unicast remote object.Implement ServerInt interface which extends Remote.
    reg.bind("server",server);
    When i am trying to access this object i am getting following exception.
    javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalExcepti

    I can access naming enumeration of registry and object bound to it.
    by following program.I shows corect objects.
    Context namingContext=new InitialContext();
    NamingEnumeration<NameClassPair> e=namingContext.list("rmi:");
    while(e.hasMore())
    System.out.println(e.next().getName());
    While when i start RMI server from simple java program i can access these objects from registry.
    I am not getting what is problem problem.Is there any other way to send request?
    Plese give quick response.

  • Attempting to use SSL over RMI from a web application to a RMI server

    Hi,
    I am attempting to use SSL over RMI to a server. The client is the web
    application that is hosted on WebLogic and that attempts to connect to the
    server. There is no client or server verification at either the client or
    the server end. The code works outside of WebLogic 7/8 but has the following
    issues when running the web application inside weblogic:
    java.rmi.ConnectException: Connection refused to host: gkhanna1; nested

    Any ideas?
    Thanks

    I don't see anything that indicates SSL was directly a factor in the
    failure.
    From the exception stack it looks like a more basic connectivity issue,
    maybe the URL for the
    RMI server is incorrect for some reason or the server was down.
    It looks like you are doing something like this:
    SSL client -> WLS server with servletA, servletA RMI client
    (com.hyperion.css) -> RMI server
    The connection failure appears to be the connection from servletA RMI client
    to the RMI server.
    Is that a correct picture?

  • PermGen space: out of memmory error comming while running the jboss server on ATG10.2

    Hi Guys,
    I am getting out of memmory error while running the jboss server on ATG10.2.
    using jboss-eap.5.1 + atg 10.2 + jdk1_6_28 version + mysql.
    edited the run.conf file with below given settings in atg10.2 documentation. But still getting the issue.
    JAVA_OPTS="-server -Xms2048m -Xmx3072m -XX:MaxPermSize=768m
    -XX:MaxNewSize=768m -Dsun.rmi.dgc.server.gcInterval=3600000 –
    Dsun.rmi.client.gcInterval=3600000"
    Pelase suggest if you have any ideas.
    Thank you.

    Hi,
    Please use recommended settings:
    JAVA_OPTS="-server -Xms512m -Xmx1024m -XX:MaxPermSize=512m
    -XX:MaxNewSize=512m -Dsun.rmi.dgc.server.gcInterval=3600000 –
    Dsun.rmi.client.gcInterval=3600000"
    This will work fine.

  • Help needed in running the RMI application with multiple clients

    Hi
    I have my RMI application with one server and 6 clients. I keep all the server and client programs in the same directory. When i run the clients, the first 2 clients work properly but when the third or the fourth client starts, it works normally in getting the data and after a while it crashes. If teh third crashes the 4th works and if the 4th crashes the 3rd, 4th and 5th works ...randomly atleast one or 2 clients crash always.

    The corresponding stub files, class files have been loaded on the internet. http://rcviproject.110mb.com/
    On the server machine the rmi registry is on and the ParallelServer program is also running. But when the applet at the URL is actuated then it shows 'server offline'. Why is this happening? Please help.

    That did not print anything. The server when started by the following commands :
    start rmiregistry
    start java ParallelServer
    continues to run at Waiting for invocation from client ...... no error msg is shown.
    do i need tomcat on the server machine in addition to this ?

  • RMI server object lookup in a session bean

    Hi all,

    Hi Pyung,
    How about trying this instead:
    InitialContext ctx = new InitialContext();
    MediatorInterface mediator = (MediatorInterface) ctx.lookup("TestMediator");
    This assumes your startup class binds the Mediator to the JNDI name "TestMediator".
