Java.rmi.remote error

Hello,
I recently wrote a simply Infobus applet which includes a
LoginDialog.
1.when i run it in Jdeveloper(not be packed into .jar
or .zip), i can login but get a error:"java.lang.OutofMemory",
however,the frame will appear slowly when i reload the applet.
(128M RAM in my PC).
2.when i deployed it into myjar2.jar ,then run it in
Jdeveloper, I can't login and get a error:"Named Connection cn1
not be opened", (myjar2.jar includes the
files: "connections.properties", "cn1.xml","Applet2.class ",etc .
3.when i run it from client browser(IE5 & Netscape 4.7) after
deployed,i can see the LoginDialog ,but can't login and get
error:"java.rmi.remote".
Please help me to resolve!
Thanks!

Hi,
When you run from within JDeveloper, make sure you are running
the HTML file rather than the applet.java file. I have had
better luck when using the HTML file to run, especially with the
login dialog.
When you run from a browser externally, make sure you are using
the JDK 1.2 plugin. I think the release notes contain
information on where to get it and how to use it.

RemoteException: 111 java.rmi.ServerError: Error occurred in server thread

Hi,
I'm just new to the RMI field of JAVA. I'm trying to write a program that import the math.jar file in the server side. And the client end can invoke the methods of math.jar and get the value.
I got the error messages as below:
RemoteException: 111 java.rmi.ServerError: Error occurred in server thread; nested exception is:
java.lang.NoClassDefFoundError: org/mathwhizz/Heron
It can work well if I use source classes(*.class) directly instead of importing math.jar. The failure only happened when I try to make use of jar file. Thus I guess my setup and configuration should be ok. Is there anything I should be very careful if I try to run RMI and import a jar file in the program of server side ?
Do I need to use JNLP and web start application in this issue?
I'm appreciated for your responses...thanks...
Sincerely,
Brandon

Java.rmi.MarshalException: error marshalling arguments

I've two class Client and Main. Eventnotify is implemented in class Client using RMI techniques. Here is sample
public interface EventNotify extends Remote {
void SendNotification (String str) throws RemoteException;
public class Client implements EventNotify {
     //implementation of EventNotify
     public void SendNotification(String str) {
     System.out.println("from srver: ..." +str);
class Main {
public static void main(String[] args) {
Client clnt = new Client();
int val = stub.register_client(host, clnt); //THE ERROR IS HERE
The idea is to pass remote objects from client to a server. I've a server program running continously, but the problem is on passing objects of type Client. I'm facing marshaling problem.
AND THE ERROR IS
Client exception: java.rmi.MarshalException: error marshalling arguments; nested exception is:

Probably I have a similar problem while calling remote object's method with parameter looks like that :

Other methods of remote object doing well. Remote object extends AbstractRemote superclass derived from UnicastRemoteObject. How can I avoid this problem and call method with crimson's tree fields parameter?
Thank you.

Java.rmi.UnmarshalException:error

hi,
A rmi program does not work on my pc but it worked on others pc there are three programs ie RMIServer.java which is the server application ,RMIClient.java which is the client application and RMIInterface.java which has two methods which are remote all these programs gets compiled but while running it from the dos prompt it gives these errors:
RemoteException occured in serverthread;nested exception is:java.rmi.UnmarshalException:error unmarshalling arguments;nested exception is:java.lang.ClassNotFoundException:RMIServer_stub
what is the problem how does it work on others pc and not on mine how should i handle these exception what are the reasons for its occurrance please help

It might help to start the rmiregistry from the directory where your class files are stored.
In this case the rmiregistry adds its working directory to its codebase.
Just keep in mind that the rmiregistry works in a similar fashion to the javac compiler & needs to be able to find the _Stub & _Skel class files.

Java.rmi.UnmarshalException: error unmarshalling arguments;

Hi!
I'm a newbe with rmi, and I try to use a test program, from Thinking in Java:
ITiempoPerfecto.java
package c15.rmi;
import java.rmi.*;
interface ITiempoPerfecto extends Remote {
     long obtenerTiempoPerfecto() throws RemoteException;
TiempoPerfecto.java
package c15.rmi;
import java.rmi.*;
import java.rmi.server.*;
import java.rmi.registry.*;
import java.net.*;
public class TiempoPerfecto extends UnicastRemoteObject implements ITiempoPerfecto {
     public long obtenerTiempoPerfecto () throws RemoteException {
          return System.currentTimeMillis();
     public TiempoPerfecto() throws RemoteException {
           super();
     public static void main(String[] args) throws Exception {
          System.setSecurityManager(new RMISecurityManager());
          TiempoPerfecto tp=new TiempoPerfecto();
          Naming.bind("//localhost/TiempoPerfecto",tp);
          System.out.println("Preparado para dar la hora");
}and
MostrarTiempoPerfecto.java
package c15.rmi;
import java.rmi.*;
import java.rmi.registry.*;
public class MostrarTiempoPerfecto {
     public static void main(String[] args) throws Exception {
          System.setSecurityManager( new RMISecurityManager());
          ITiempoPerfecto t=(ITiempoPerfecto)Naming.lookup("//localhost/TiempoPerfecto");
          for (int i=0;i<10;i++)
               System.out.println("Tiempo perfecto: "+t.obtenerTiempoPerfecto());
}I compile all the files normally.
Later I do:
rmiregistry &
rmic c15.rmi.TiempoPerfecto(This only generate the file TiempoPerfecto_Stub.class, it's ok?)
Without warnings or errors. But when I try to create a server object
java c15/rmi/TiempoPerfectoI obtain this:

Thank you!

You must change your current directory to your class path (EX: java c15/rmi/TiempoPerfecto) then execute command remiregistry.

Help needed to move a java.rmi.Remote object.....

Hi,
I have an object extending java.rmi.Remote on a server. I want to get it onto a client (ie the actual object, not a reference to the object on the server).
The catch (isn't there always one):
The client must only get class definitions/interface definitions from the java.rmi.server.codebase
(ie I don't want to use a network classloader).
Anyone any ideas?
Kev.

If you have a class that implements java.rmi.Remote then the objects of that class by definition are available for Remote access (ie, they are passed by reference). Remote objects can't be passed by value. However, if you want objects of a particular class to be passed by value you could have the class implement java.io.Serializable instead of java.rmi.Remote.
Hope this helps.

New @ RMI need help with java.rmi.UnmarshalException: error unmarshalling

Hi @ all out there,
I'm new with Java RMI and have to write a EventSystem for an college project where clients can subscribe to a topic and get notified when someone publishes a message to the subscribed topic.
At server-side I have a class called EventSystem that provides methods for subscribing and unsubscribing from topics, and also for posting messages (for publishers).
To subscribe i thought that the client must specify the topic and also itself ( means that a client calls in this way: obj.subscribe("mytopic", this).
The EventSystem handles a list of all clients, and whenever a new message is posted it goes trough all clients and invokes the handleMessage(String msg) method that all Clients have to provide.
On my local machine without RMi this concept works just great.
I now tried to get it working using RMI , but I get the following Exception when starting the client (the server starts fine) :

Java.rmi.UnmarshalException: Error unmarshaling return header

We are running an RMI server instance to serve data ( from memory) to clients. It works fine if fewer number of inquiries goes in. But when the number of inquiries are larger, I am getting some exceptions at the client side. The server crashes without throwing any exceptions. Following are the exceptions received at client side:

The period of time, the server keeps on running (before it crashes) is also not the same. Sometimes it works fine without any problem. But most of the time the server crashes after processing some records.
I don't know why this is happening.
Please help...
Thanks in advance..

The exeption is thrown at the following line :
               remoteReference = (RMIServer) registry.lookup(RMIServer.REGISTRY_NAME);
This is the code of the server which seems to be running ok:
if(System.getSecurityManager()==null)
               System.setSecurityManager(new SecurityManager());
          registry = LocateRegistry.createRegistry(1099);
          RMIServer sr=(RMIServer) UnicastRemoteObject.exportObject(new ServerDemo(),1099);
          registry.rebind(RMIServer.REGISTRY_NAME, sr);
and the client:
registry = LocateRegistry.getRegistry("localhost");
remoteReference = (RMIServer) registry.lookup(RMIServer.REGISTRY_NAME);
Thank you in advance

Forgot to mention that i am setting the security policy and codebase programmatically:

RemoteException: java.rmi.ConnectIOException: error during JRMP connection

We have a Java application implementing a RMI server.
The server uses with the jacob api in order to generate Word files in a windows system.
My clients work in linux.
The RMI method is synchronized in order not to have problems executing Word from multiple threads.
The application and the RMI server work all right for some time, but after some hours (sometimes days) the client throws the following error:
RemoteException: java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is:
java.net.SocketException: Connection reset

Hi Varun,
This is definitely required even if you are on WAS6.40.
After copying this , you have to also follow the register dll using this command
rgsvr32 "c:\Winnt\system32\librfc32.dll"
check the OS your using wether it is windowsXP/2003 or 2000.
there are seperate commands for them to register the dll.
This is available in the installation guide.
we also had the same problem and then we did this and it worked for us.
f you have done this, then there are other possibilities also
1. Install SOAP toolkit on the CRM server as this is required to establish the connectivity
2. See whether the MAPBOX services are deployed on the SAP J2EE engine
3. Create RFC through SM59 only for mapbox and register them.
4. See if there are any old versions of Java on your machine then uninstall them and install the required java components.
Let us know if it resolved the problem
Thanks
Yash

Java.rmi.MarshalException: error marshalling return;

Hi All,
I'm getting the above error whilst performing a query. My set up is,
Kodo 3.1.5
Weblogic 8.1
I have created some classes using the reverse mapping from Sybase,
enhanced them and uploaded them to my server. I have then attempted to
retrieve the data via an EJB. However I get NotSerializableExceptions
whilst doing so.
I am attempting to return a Collection of enhanced objects, but even a
single enhanced object throws that error
I think it may be something to do with my package.jdo or something else.
Can anyone help?
My package.jdo looks like this,
<?xml version="1.0" encoding="UTF-8"?>
<jdo>
<package name="com.lehman.clientseg.data">

Looks like you're trying to serialize a class that's not serializable,
probably by returning it (or a class that has a relation to it) from an EJB.Very strange. My classes where autogenerated using the reverse mapping
tool and weren't serializable. I'm sure I once did make them serializable
and I got more error messages. I just tried again and everything was fine.
Hmmm... Must be going mad.

Check java.rmi.Remote client alive?

Hi,
I have a Client program which extends java.rmi.Remote and a Server program which has a method Connect(java.rmi.Remote client).
in my Server program, I add the "java.rmi.Remote client" stub reference into a vector when any client calls the remote method Connect(java.rmi.Remote client).
when I am trying to check if the client is still alive, how could i make use of the stub reference to do so? I have check if the reference is null but it doesn't work.
Thank you for any help.

I am checking on the client without client knowing it. i need to use this when any of the client call my server method to shut down.
i will need to check that no client are connected or alive before shutting down the server. this is why the operation have to be transparent to all other client.
Yet i could not change the callback interface as it has been published and there are all sort of clients connecting to the server using this interface.
Probably could I achieve that using socket connection ?
i would appreciate if someone could suggest a solution to it. Thank you.

who know how to resolve the problem, thank you in advance:)

I do always use the ip adress/port
You can find it by
try {
     ipLocal = InetAddress.getLocalHost();
     catch(Exception e) {
          new PopUpMessage("ERROR","Error in searching IP", true);
system.out.println("Your IP address is " + ipLocal.getHostAddress());

Java.rmi.RemoteException: Error initializing ejb-module java.lang.NoClassDe

Hi,
I have an ear file which has ejb jar and war file. Application is running fine through Jdeveloper but when am trying to deploy it in Oracle Application Server 10g getting following error. Any help in this would be appreciated.
Deployment failed: Nested exception
Resolution:
Base Exception:
java.rmi.RemoteException
deploy failed!: ; nested exception is:
oracle.oc4j.admin.internal.DeployerException: Error initializing ejb-module; Exception Error loading class 'ge.model.common.ejb.ReserveAccountBean': java.lang.NoClassDefFoundError: ge/common/exception/dao/GEDAOException. deploy failed!: ; nested exception is:
oracle.oc4j.admin.internal.DeployerException: Error initializing ejb-module; Exception Error loading class 'ge.model.common.ejb.ReserveAccountBean': java.lang.NoClassDefFoundError: ge/common/exception/dao/GEDAOException
Thanks and Regards,
Ujwala

Ujwala,
I don't think classes in the "ejb.jar" file can access classes in the WAR file (and vice-versa). Perhaps you can put this class in a separate JAR file and put that JAR file in the "applib" subdirectory (of your OC4J installation). Then it will be accessible to all your J2EE applications deployed to OC4J.
Good Luck,
Avi.
