RMI - Unmarshell Exception - Nested Exception is java.io.EOFException
Hi,
I get the following error while executing my RMI client.
The fact is that i dont get this everytime. When i make nearly 4000 RMI method calls then for the further method calls i get the exception as given below..
*java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is:*
* java.io.EOFException*My RMI Client Implementation is like this.
- Create a static object of RMI Client
m_objRmiServiceProxy = (IExposedInterface) Naming.lookup(ConnectionURL);And use the same object for all my further rmi server calls....
can anyone tell me when we will get the above exception?
What can be the possible cause for it ?
Thanks...
If you find an answer elsewhere please let me know, your problem seems to be very much akin to what my program is experiencing. Just one question, is your program affected by the error if you call the one remoteserver method consecutive times or if you call multiple methods in parallel?

BUILD SUCCESSFUL (total time: 6 seconds)Looks like the server is sending a namespace qualified response when a non-qualified response is expected. If you are accessing a .NET endpoint this is a known issue with their implementation.

Service call exception; nested exception is: java.lang.IllegalMonitorStateE
Hi All,
when we try to run the Message Monitoring in our RWB then we get the following error:
Service call exception; nested exception is: java.lang.IllegalMonitorStateException
Has anybody of you an idea what this error occurs?
Thank you for the support..
Kind Regards
Markushi,
restarting the java stack would be enough. You can do that at SMICM. Before you should deregister all queues in SMQR so that incoming messages has to wait in the queue. Of coz all synchronous msgs would fail, as well messages going to your Java Inbound Adapters.
note:reward points if solution found helpfull.....

EJB:nested exception is Java.lang.NullpointerException
Our application is using WLS8.1 sp6 and developed based on EJB,Struts and J2EE.My problem is that the following exception
"EJB Exception: ; nested exception is:
java.lang.NullPointerException"
is occuring sporadically over a week.I know why a NPE occurs but not sure what caused that NPE to occur sometimes and defer most of the times.
Could anyone of you shed some light on this?Transaction was rolled back: java.lang.NullPointerException
Is a value added for a NOT NULL column null? -
EJB 3.0 Application Client threw Remote nested exception
Hi All,
I came across the following EJBException message when trying to retrieve an Employee record (entity bean in EJB 3.0) after having successfully added it into EMPLOYEE table using stateless session bean:

at client.EmployeeApplicationClient.main(EmployeeApplicationClient.java:55)
Below is the code snippets of EmployeeApplicationClient.java:
public class EmployeeApplicationClient {
@EJB
private static EmployeeRemote employeebean1;
@EJB
private static EmployeeRemote employeebean2;
public EmployeeApplicationClient() {}
public static void main(String[] args)
EmployeeApplicationClient employee_application_client = new EmployeeApplicationClient();
employee_application_client.addEmployee(1, John, Smith);
employee_application_client.printEmployee(1);
public void addEmployee(int id, String firstname, String surname)
try {
Employee employee1 = new Employee();
employee1.setID(id);
employee1.setfirstname(firstname);
employee1.setsurname(surname);
employeebean1.createEmployee(employee1);
catch {.....}
public void printEmployee(int employee_id)
Employee employee2 = employeebean2.findEmployee(employee_id);
System.out.println("employee Id: " + employeebean2.getId());
System.out.println("employee firstname: " + employeebean2.getfirstname());
System.out.println("employee surname: " + employeebean2.getsurname());
}Using employeebean1/employeebean2 in printEmployee() did not make any difference.
The error message appears to indicate that I have incorrectly structured these methods.
The deployment of EmployeeBean was successful and employee1 is in EMPLOYEE table via SQL query.
I am using JDK1.6.07, Glassfish v2 with MySQL 5.0 and Netbeans 6.1 on Windows XP platform.
Any assistance would be greatly appreciated.
Thanks,
JackHi Ataraxisme,
Thank you for responding to this post.
This is a J2EE Application Client that was created and deployed along as an Netbeans EAR (both Application Client and EJB) project which uses resource injection as opposed to JNDI lookup.
I am trying to get employeeApplicationClient.java to work the same way as the following travelAgentApplicationClient.java example which has successfully retrieved its record record immediately after adding using resource injection:
public class TravelAgentClient {
@EJB
private static TravelAgentRemote travelagent;
public TravelAgentClient() {
public static void main(String[] args) {
TravelAgentClient client = new TravelAgentClient();
client.doTravelAgent();
public void doTravelAgent() {
try {
Cabin cabin_1 = new Cabin();
cabin_1.setId(1);
cabin_1.setName("Master Suite");
cabin_1.setDeckLevel(1);
cabin_1.setShipId(1);
cabin_1.setBedCount(3);
travelagent.createCabin(cabin_1);
Cabin cabin_2 = travelagent.findCabin(1);
System.out.println(cabin_2.getName());
System.out.println(cabin_2.getDeckLevel());
System.out.println(cabin_2.getShipId());
System.out.println(cabin_2.getBedCount());
......Thanks,

MulticastMonitor -- Failed with IOException java.io.EOFException
Hello,
I have upgraded Weblogic Server 8.1 Sp4 with Weblogic Server 8.1 Sp5 and JDK 1.4.2_12.
With the Sp5 the cluster seems work, but if i try to use the MulticastMonitor utility i have the following exception :
Failed with IOException java.io.EOFException
With the SP4 the utility works and the cluster also.
What's happening?
Best Regards

Java.rmi.ServerError: A error occurred the server; nested exception is:
Hello Guys,
I'm getting the following error when calling a method of a normally
deployed facade session bean.
java.rmi.ServerError: A error occurred the server; nested exception is:
java.lang.AbstractMethodError
It's very confusing, it sometimes appear and sometimes the method is
invoked normally.
Thanks in advance for ur help.

[att1.html]That error means your are not running xserver process. Or, your ssh connection is not set-up to forward X-11 data.

I have a project that I am porting from WL5.1 to WL6. It was working fine
in WL5.1
but cannot get it working in WL6. So, I went back to the HelloWorld
example to
see if I could get it working. The problem I am having is basically getting
applet to
talk to a server via RMI. The applet works fine alone and RMI works fine
alone.
I can't get the applet to talk to the server via RMI.
I am trying to get the "HelloWorld" applet example in WL6 working with RMI.
I previously had the same app working in WL5.1 with SP9 but cannot get it
working in WL6.
I am running WebLogic Server 6.0 with SP2.
I have registered a startup class in the WebLogic console
named "HelloServer". When starting up the server, it states
that the HelloImpl class has been registered as "HelloServer".
When starting up the client applet I get the following error:
java.rmi.MarshalException: Error marshaling transport header; nested
exception is:
java.io.EOFException
These are two different methods of looking up the same object.
The exception occurs at the "lookup" method call in both cases.
"myserver" is the name of my machine that WL is running on.
7001 is the port that WL is using.
Registry reg = LocateRegistry.getRegistry("myserver", 7001);
obj = (Hello)reg.lookup("HelloServer");
or...
obj = (Hello)weblogic.rmi.Naming.lookup("rmi://" +
getCodeBase().getHost() + ':' + port + "/HelloServer");
I previously ran this same program under WL5.1 SP9 and everything works
fine.
I defined the startupClass in the weblogic.properties file in WL5.1
Can anyone tell my what is causing this exception and how to correct the
problem?
Thanks

Error in PI mapping "nested exception is: java.lang.OutOfMemoryError "
Hi Experts ,
I encounter an error in the PI mapping while calling a Java Mapping (Mercator Map)
Error Message as ::-
java.lang.RuntimeException: RemoteException in setMercGeneral: Error occurred in server thread; nested exception is: java.lang.OutOfMemoryError at com.philips.xi.mercator.MercatorCall.execute(MercatorCall.java:90) at
Could anyone suggest , how we can overcome this error message
I have also tried to restart the RMI Server , but that was not not helpful.
Regards,
ShwetaSweta,
Is this a java mapping or Graphical, If Java, you should not run into this issue as you dont load the nested XSD`s.
Also the error message indicates outofMemory in mercator side when posting your Large message.
java.lang.OutOfMemoryError at com.philips.xi.mercator.MercatorCall.execute(MercatorCall.java:90) at

[java] Java Result: 1Hi,
Before connecting through your main program, you have to keep ready your catching object. Mean to say first you have to run local method which will be waiting for remote method to catch.

Unmarshalling return; nested exception is: java.lang.ClassNotFoundException
I think what I'm trying to achieve is probably very simple (or at least should be) but I've been trying for at least 5 hrs now:
I'm using RMI for a distributed app I'm building for my degree.
Up until today I got around the need for using a SecurityManager by including all shared classes (those I pass between client and server) in a class library .jar file referenced by both client and server projects.
This has worked fine, but now I've coded a method that returns an object of a class that I do NOT want to include in the shared library (because I don't want the client to be able to construct these objects); therefore, I've decided to try and get the dynamic class loading working.
I'm using netbeans and testing on a single computer.
Here's what I'm trying:
My main() method has the standard code I've seen: if (System.getSecurityManager() == null) System.setSecurityManager(new RMISecurityManager());
In the server project's Run properties, I'm specifying VM Options: -Djava.security.policy=c:\security.policy -Djava.rmi.server.codebase="file://C:/"
I've copied the ellusive class's .java file into C:\ to keep the URL simple, but I've also tried directing it to the netbean project's bin\ folder using '%20' for spaces, both with the same results - about a five second pause (so it's finding something I think) and then the error message from the client's output:
error unmarshalling return; nested exception is: java.lang.ClassNotFoundException: mypackage.myClass
My policy file's contents are:
grant {
permission java.security.AllPermission;
I've tried about 20 different ways of formatting the codebase argument's URL.. can anyone help?
David
p.s. my OS is Windows 7Thanks EJP,
Yes, after posting I guessed it might want the .class file instead, so I directed it their instead - still no joy, unfortunately!
I'm carrying out all testing on one computer, so (+if+ I could get it to work) a local codebase address would not be a problem.
Noted about the server-side security manager. I might want to use callbacks, but the server still won't need to download class files from the client, so I'll still try and set the codebase, but will try without loading a security manager on the server-side.
For the time being I've put the class in the shared library but have defined it within the same package as the server code. By doing this I've been able to set the class's accessibility back to default, but the client can still access it as Object (from the shared library).
This solution is good enough, but I still wonder why the client refuses to accept the class file from the C:\ codebase.
Maybe you are looking for
