Doubt on Throwing own exceptions in java rmi?

Hello,
I am writing my own exception class and want to send exception object to the specific client.
But, Exception class constructor only accept string.
If I want to send both string and its corresponding error constant, how can I throw it.
thank you.

But, Exception class constructor only accept string.That is simply untrue. Have another look.

java.lang.ClassNotFoundException: RMITest.myRMIInterfaceThe Registry can't find that class on its CLASSPATH.
Solution: do something about that. Either run the registry as a separate task with a suitable CLASSPATH setting, or run it in the server JVM via LocateRegistry.createRegistry().

How do i throw BPEL exception from java embedded activity

Hello everybody,
i want to use some embedded java code in my BPEL process (bpelx:exec). This code would sometimes throw exceptions. How can i deal with these exceptions to control my BPEL process? I would like, in a sense, to do some catching of java exceptions but at the BPEL level... for example, my java code would throw an exception, that my BPEL process would "catch" and react the way i want. Is it possible to do that?
Thanks for your help!

RemoteException: java.rmi.UnmarshalException in jdk 1.4.2

i'm implementing an RMI over the jdk 1.4.2 (can't do it in the 1.5 or 1.6) i've seen this topic [http://forum.java.sun.com/thread.jspa?threadID=370196&messageID=1808449] but it didn't help me, or i'm doing something wrong...
i know the RMI code is ok because it runs on java 1.6 (with the automatic generation of stubs and skeletons) but when i change the platform to 1.4 it throws the exception:

}NOTE: my IDE is Netbeans 6.1. and the client and server are in diffrent projects
thanks in advance
Best Regards,
Carlos Daniel Ribeiro

the stub and the skeleton are being generated, and they are there, in the server project! i don't know why the class defs for the stub filearen't downloded by the client project...I don't know why you think they will be downloaded. They won't be, unless you're using the codebase feature. The client needs the remote interface and the stub on its classpath, and all classes that the remote interface depends on, and so on recursively until closure. You have to do something about that.
It works under 1.6 because it doesn't need the stub at all.

UnmarshalException while using prop java.rmi.server.ignoreStubClasses=true

I have created a test program to check the behaviour of setting the java.rmi.server.ignoreStubClasses property to true on the server side and not setting this flag on the client side.
This requirement is due to updation of an already running system, with stubs to a new version without stubs, without shutting down the system.

// Bind the remote object's stub in the registry
Registry registry = LocateRegistry.getRegistry();
registry.bind("Hello", stub);

I am not able to figure out why this thing is happening, If i also set the property java.rmi.server.ignoreStubClasses=true on the client side everything goes fine. But this I can't do. I can't set the property on the client side as the system is up and already running.
I am using JDK version 1.5.0_06. Same exception comes under JDK 6.0
Any help will be highly appreciated.

I think this is a bug. When you exported the Registry from your server JVM it was also exported with java.rmi.server.ignoreStubClasses=true, but the Registry bootstrap at the client requires the 1.1 stub protocol for compatiblity reasons so you got this error. I would report this on the Bug Parade.
You could get around it by setting java.rmi.server.ignoreStubClasses after exporting the Registry.
BTW java.rmi.server.ignoreStubClasses isn't supposed to do anything at the client whether true or false so you can cut your testing space in half.

Well this error occurs if the RMI files are different on the server and client side.
It basically tells you that the stub and skeleton don't match with each other. Get the latest version of the RMI jar file or whatever file you are using on the server side to replace the file you are using oon the client side. This would make stub and skeletons to communicate with each other effectively . enjoy :)

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:
     java.io.NotSerializableException: Client
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 :
public class ParamClass extends AbstractParamClass implements Runnable,
        java.io.Serializable {
    private NodeList field1; // part of crimson's tree
    private NamedNodeMap field2 = null;// part of crimson's tree
public class RmiRemote extends AbstractRemote { // Remote Object Class
@Override
public Object remoteMethod1() throws RemoteException{
ParamClass param = new ParamClass("build with crimson");
CustomInterface stub = (CustomInterface) registry.lookup(name);
stub.callRemoteMethod(param); // exception here
java.rmi.MarshalException: error marshalling arguments; nested exception is:
        java.io.NotSerializableException: org.apache.crimson.tree.AttributeSet

        at java.rmi.server.RemoteObjectInvocationHandler.invokeRemoteMethod(RemoteObjectInvocationHandler.java:178)when I build param object with xerces - no exception occurs . 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 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:
Exception in thread "main" java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
        java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:

.......What is the mistake? What may I do to run this programs?
Thank you!

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

Javax.ejb.CreateException, java.rmi.RemoteException

When I deployed my war file and jar file on jboss server I am getting the following exception:
what will be cause:
10:32:03,051 ERROR [LogInterceptor] EJBException in method: public abstract com.cisco.avm.jbossmysqlejb.CustomerSessionRemote com.cisco.avm.jbossmysqlejb.CustomerSessionRemoteHome.create() throws javax.ejb.CreateException,java.rmi.RemoteException:

SLSB have only one constructor. If you have another overloaded. It will never be called.

Hi,
I had the same problem. In my machine, path was having jre1.1.7 before my jdk 1.4. So it was picking up from jre1.1.7.
Java was happy when I moved my jdk1.4 path to the beginning of the path variable.
Hope this helps you.

Doubt on Throwing own exceptions in java rmi?
