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
reward points if it helps.

I am havin some problem with RMI. Let me explain the application a bit first.
I've an application form which invokes some remote method from the database (oracle). Since oracle cannot call remote methods directly from database, we use a bridge which is developed in java.
In order to run that i do the following in a batch file:
start rmiregistry 2607
rem Attempt to run the bridge
echo Runing the bridge ...
java com.cramer.syncengine.RegisterBridge
the service starts up successfully without any prob.
Now, when im using the application (which requires this RMI bridge and RMI registry) i'm getting the following error.
Starting the RMI Registry...
Runing the bridge ...
Object instantiated: com.cramer.syncengine.SyncEngineBridgeServer[RemoteStub [ref: [endpoint:[172.24.5.99:1519](local),objID:[0]]]]
java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is:
java.net.SocketTimeoutException: Read timed out
If anyone can help me out to understand where the problem is?It looks like your server is timing out trying to bind itself to the Registry. You might need to allow a little time for the Registry to get itself started before starting your server, or at least between the export and the bind inside your server code, or just retry the bind a couple of times after increasing intervals before bailing out.

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:
RemoteException: java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: servidor.MensageiroImpl_Stub
the VM is configured to use the -Djava.security.policy=C:\Projecto\Policy\permissions.policy both in the client and server
please help me :S i've been burning my head with this for 3 days
i leave my code here:
The interface:
package rmiinterface;
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface Mensageiro extends Remote {
public void sendMsg(String msg) throws RemoteException;
public String readMsg() throws RemoteException;
}the implementation:

}NOTE: my IDE is Netbeans 6.1. and the client and server are in diffrent projects
thanks in advance
Best Regards,
Carlos Daniel Ribeirothe 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. -
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,
BrandonI've got a problem with rmi, when I launch my server, I have this error:
Erreur du remote: java.rmi.ServerError: Error occurred in server thread; nested exception is:

Urgent Chatting RMI ( java.rmi.ConnectIOException)
hello;
I have a project cat in RMI in the network internet,le problem what the server doesn't communicate with the customer (the customer has a private address (local network) and the server has a public address (network internet)) message error:
java.rmi.ConnectIOException: Exception creating connection to: 192.168.0.27; nested exception is:
java.net.NoRouteToHostException: No routes to host
how I can solve this problem (urgent)
thank youThere are only two ways that I am aware of to do this:
1. The customer must deploy a port-forwarding device such as a NAT device, and the client must do -Djava.rmi.server.hostname= the public IP address of the NAT device prior to exporting its callback. The client must also export on a fixed port number, and the NAT device must be configured to forward this port number as appropriate.
2. Buy and deploy my RMI Proxy product at the client: http://www.rmiproxy.com

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

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 helpIt 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. -

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:

"java.rmi.UnmarshalException: error unmarshalling" at Applet with RMI comm.
Hello,
I am trying to make an Applet work with an RMI server, but i keep getting the same exception again and again whatever i do.
More specifically, i get the following :
java.rmi.UnmarshalException: error unmarshalling return; nested exception is:

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
Alex
Forgot to mention that i am setting the security policy and codebase programmatically:
System.setProperty("java.security.policy","C:\\Users\\Alex\\workspace\\Demo\\grantall.policy");
System.setProperty("java.rmi.server.codebase","C:\\Users\\Alex\\workspace\\Demo\\bin");
Edited by: Alkon on May 15, 2008 4:31 PMI edited the code that sets the security and i am now getting the following error, again at the lookup:

I am trying to edit test partner script from eca script, but i am getting one error 'ecatt error ECATT_STORE_BLOB(2)
saving of blob denied for security reasons. you may not be in the edit mode of ecatt ' when i click on ok button it is telling error during RFC connection and whatever changes i made in test partner is not saved.
How to solve this problem. Please help me.Is it working fine in the standalone mode?
Refer to the below checklist for trouble shooting:
1) Maintenance of DSN settings to the databases - TP_EDIT and TP_EXEC
2) Maintenance of R/3 connection parameters
3) Refer eCATT Security guide
4) Refer OSS note - 519858
Please note that for an integration Scenario, the connection and user information is required so that appropriate rights are established automatically.
Hope this helps!
