RMI methods Error

Hi when i run RMI application in one network it is working fine when i am running the client from another network iam getting an Exception like connectException.
when i call the methods like
s.mone();
iam getting Exception.
whether RMI support different networks or internet.

Do you have an idea ?
(everything before seems OK - context, narrow, home.create() ...)
Config : WL6.1 SP1 on Solaris 2.8 / client Win2000 jdk 1.3.1Are you using RMI-IIOP? If so I suggest you try SP3.

Errors in calling rmi methods

We have to restart iplanet whenever we get this problem and then it works fine for 40min - 1hr and it repeats the problem again. But we could make t3 connections and call rmi methods on the appserver by a test program running out of webserver without any problem at the same time when iplanet was having problems.
Did anybody face this problem before?
Thanks.

Yes I have done that and at least in terms of my code it wasn't just a result set.
But not with two.

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

I've got a problem with rmi, when I launch my server, I have this error:

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.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 :

    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

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.

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:

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:

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

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

RMI server error under Linux

Hi all,
I'm not excatly sure, whether this is the right forum. Anyway, my problem is this:
I've written a JApplet that calls several methods over RMI. The RMI server is up and running properly. Most of the functions work well. One that initializes a JTree, however, causes problems. I get the following error message and I am stumped:

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.

Kumar,
From the stack trace you have posted, it appears that in line 87 of file "ResourceMgrEJB.java" (in package "com.dsr.sov02.resourcemgr.sf"), you are invoking a non-existent method. Have you looked at that line of the code?
Good Luck,
Avi.

No such method error when launching the Interactive form

Hi Experts,
I have developed a simeple Java Webdynpro application and added an Interactive form without any controls in it. Created the context with one value node and a binary value attribute.
I have assigned value node to datasource and binary attribute to pdfSource. When I launch the application I am getting the following no such method error.
java.lang.NoSuchMethodError: com/sap/tc/webdynpro/clientserver/uielib/adobe/api/IWDInteractiveForm.setTemplateSource(Ljava/lang/String;)V
The currently executed application, or one of the components it depends on, has been compiled against class file versions that are different from the ones that are available at runtime.
If the exception message indicates, that the modified class is part of the Web Dynpro Runtime (package com.sap.tc.webdynpro.*) then the running Web Dynpro Runtime is of a version that is not compatible with the Web Dynpro Designtime (Developer Studio or Component Build Server) which has been used to build + compile the application.
My NWDS is of Version 7.0.06
and J2EE Engine is of Version 6.40.
any guess why I am getting this error.
Thanks
Chinna.

Issue solved. Compatablility issue NWDS 2.0 Version should use for NW 2004.

Abstract Method Error and XML Parsing

I am using wl6sp1. I am parsing an XML file from within the
servlet using jaxp1.1 and crimson.
Following is code:
1- SAXParserFactory spf = SAXParserFactory.newInstance();
2- sp = spf.newSAXParser();
3- xr = sp.getXMLReader();
4- xr.setContentHandler(new ParseXML());
5- xr.parse( new InputSource("Example3.xml"));
This program works fine when execute from command line but in servlet on line
3 it says:
"Abstract Method Error"
I have created XML Registry to use Crimson as XML parser rather than default.
I think somehow wl is still using jaxp1.0 which is built in
support in wlsp1.
Whats wrong with the code...or what configuration i am missing???

I'm assuming you have already put crimson.jar first in the classpath for the java
command you use to start WebLogic. If so, have you tried putting the servlet in
a .war file with the crimson.jar in its' WEB-INF/lib directory?

Mike Wooten

Abstract Method Error in retrieving Blob

Hi!
while (rs.next())
Blob blob=rs.getBlob(1);
throws Abstract Method Error
why?
Thanxs in advance

You'll probably find that the JDBC driver that you are using doesn't support blobs. Check the documentation that comes with your driver, it should tell you what parts of the JDBC specification it supports.
