Weblogic.rmi.NoSuchObjectException

Hi,
Can someone tell me what could cause the weblogic.rmi.NoSuchObjectException to be thrown?
Thanks,
Ullas.

probably the remote object has been collected by DGC.

Java.rmi.NoSuchObjectException problems

Hello,
After calling home.create() in my code, passing in primary key and
additional column data, when I call home.findByPrimaryKey (primkey)
followed by a call to one of the methods in the bean, I immediately get
a a java.rmi.NoSuchObjectException.
An exception is not thrown when calling home.findByPrimaryKey (primkey)
so it is safe to assume that a reference has been obtained to the bean
with the data I am looking for, correct? If so, why am I getting this
exception:
java.rmi.NoSuchObjectException: Bean with primary key: 'Pat Hardy' not
found in
home: 'Student'
at
weblogic.ejb.internal.EntityEJBContext.load(EntityEJBContext.java:153

va:212)
at
weblogic.ejb.internal.StatefulEJBObject.getContextForInvoke(StatefulE
JBObject.java:162)
etc.
etc.
etc.
Any ideas of what I might be doing wrong?
Thanks for your help in advance.

We had a similar problem, although I don't know if it was the same
thing. We are using WL 5.1, sp5, with Oracle 8.1.6.
I have a stateless session bean, which had a transactional attribute
of 'Supports'. It would call an entity bean with transactional attribute
of 'RequiresNew' for all methods. The session bean would do a finder
on the entity bean, and if it got an ObjectNotFoundException, it would
then create the entity bean with a call to home.create(id). Then, it would
call a business method on the entity bean.
For some reason, in the case where the session bean is called from within
a thread that already had a transaction started, the call to the entity
bean business method would hang, if an only if it had to create a new
bean first. If the finder of the bean succeeded, there would be no hang.
Sometimes, instead of hanging, it would return a NoSuchObjectException.
If the stateless bean were called outside of a transaction, would always
succeed, regardless.
So, my fix, was to set the transactional attribute for the stateless bean to
'NotSupported' for all methods. It now seems to work in all cases,
no more hangs or NoSuchObjectExceptions....
Is this expected behavior? Is this related to the same problem?
The BEA recomendations to use READ-COMMITTED are useless for
the case where you are running a clustered environment, and where you
need to have the bean deployed on all servers in the cluster for
fail-over reliability.....

I dont' know about the mapping to CHAR but we've managed to fix our nosuch
object problem.
BEA sent me this snippet:
The bug is as follows
In Oracle (8.0.5), if there is a primary key constraint AND you use an
isolation
level of SERIALIZABLE, an insert followed by an update in the same
transaction
fails. Specifically, the insert succeeds (to all outward indications),
but the update fails (the returned count is 0) after some number of
iterations.
What's the workaround? If the customer is not sharing the database with
any
other app or running it under a cluster, tell them to set the isolation
level to
read_committed. Serializable only slows them down without any added
benefit.
If clustering is on, and serializable behavior is deemed essential for
this
particular bean, maybe they can deploy the bean on only one of the
servers
to reduce it to the case above.
I set the isolation level on our beans to read_commited. Fixed theproblem
although we're using Oracle 8i not 8.0.5.

Well, it appears, that you cannot map a java.lang.String to a CHAR inOracle.
A java.lang.String can be mapped to a VARCHAR2.
Is this a bug?

Still have the same problems.
Will keep you posted.

          i hope i am in the correct newsgroup...please let me know if i am not.
          i am doing some research for the programmers at my job and was wondering if anyone
          migth be able to help me out?
          we are running weblogic 6.1 and receivng the following error:
          java.rmi.NoSuchObjectException: RemoteInvokable - id: '407'
          no one is certain why the error is happening or what it means. i would be so thankful
          if anyone here might know the answer.
          thank you!


I think this problem is caused by the jvm garbage collecting the remote object.

What's the deal on this error... is it related to
          <Server

          or is it something else ?

Ramkumar,
          Here is a short explanation about the errors - the RJVM received requests for a
          remote invokable which had the internal ID 268. As this object was not available
          any longer, the RJVM threw the NoSuchObjectExceptions. In theory this could be
          any RemoteInvocable Object. For further analsis on what could be causing your
          problem I suggest you open a support case.

Questions on Weblogic RMI

Hi
          I've a few questions on WL RMI that I couldn't figure out from the
          documentation.
          Suppose I have a cluster containing Weblogic servers server1 and server2.
          Server1 hosts an RMI object o1 that is bind to the cluster wide JNDI tree.
          O1 implements remote interface i1 that has a method m1 which takes as an
          argument an object o2 implementing remote interface i2. That is:
          public class o1 implements i1 {...}
          public interface i1 extends weblogic.rmi.Remote {
          public void m1 (i2 _o2);
          public class o2 implements i2 {...}
          public interface i2 extends weblogic.rmi.Remote {...}
          Now if inside server2 I create o2 using the default constructor, lookup a
          reference to o1 and call method m1, will o2 get passed by value or by
          reference? Is there any way to control this? What if I don't use the
          constructor to create the object but the object is hosted in server2 and I
          get a reference to the object using JNDI lookup? In short, how does WL RMI
          decide when to pass an object by reference and when by value.
          I'm trying to increase the scalability of a system by distributing its
          modules as RMI objects to several machines running Weblogic server, and I
          need to know the details on how WL RMI works. The documentation seems to be
          rather inadequate...
          Thanks for reading this far :)

Actually, O2 will always be passed by reference because it is an RMI object
          (i.e., it implements weblogic.rmi.Remote). If O2 were a non-RMI object, it would
          be passed by value if O1 is in a different process and by reference if O1 and O2
          are in the same process.

I have a question about weblogic RMI , how can I resolve it.Thank you

I have a question about the weblogic RMI .
I have a program.web services+weblogic RMI +Data Sources When I run the program in the console application.it is ok.But When i run it with the web services(it 'is mean Get some parameter and run the different program).it's fail.The Exception is
cannot assign instance of yype weblogic.rmi.RMIServices_1033_WLStub to field demo.RMIServer_1033_WLStub.stubinfo of type weblogic.rmi.internal.StubInfo in instance of demo.RMIEsrver_1033_WLStub
how to resolve .Thank you.

Hi Charles,
Parental Controls has always had problems with https sites, no idea if it's fixed in 10.9.x or not.
When you setup your Mac it shouldv'e made an admin account, are you not running from that account, or did you somehow change it to a Managed account???

Java.rmi.NoSuchObjectException: no such object in table

When I try to connect to my server from an external network, I get this error: java.rmi.NoSuchObjectException: no such object in table
What is happening is I am connecting to my RMI server through a client, and the RMI server connects to a database, gets the results, and then transfers the results back to the client. It works before in an internal network, even if I'm on a different subnet. But I get that error in an external network. What does that error even mean?

I turned this to static
public class PRFromDBServer implements PRFromDatabaseInterface {
   private int      port;
    private String   ipAddress;
    private Registry registry;
    //This was recently turned static
    private static PRFromDatabaseInterface stub
    public PRFromDBServer() {
         super();
          port=1099;
          try {
              //get the address of this host.
              ipAddress= (InetAddress.getLocalHost()).toString();
              //PRFromDBServer engine=new PRFromDBServer();
              stub=(PRFromDatabaseInterface)UnicastRemoteObject.exportObject(this, 1081);
              // create the registry and bind the name and object.
              registry = LocateRegistry.createRegistry(port);
              registry.rebind("prFromDBServer", stub);
              System.out.println("IP:"+ipAddress+" Port:"+port);
          } catch (UnknownHostException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          } catch (RemoteException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
}//end Server ClassAre you saying I should turn the how class static when I insantiate it?
private static PRFromDBServer = new PRFromDBServer();

Weblogic RMI question

I am trying to implement a basic RMI class, using the example in "Programming Weblogic RMI" book. I used java rmic instead of wls rmic.
The only difference from the book example is that I am tyring to bind remote object implementation from within a servlet GET/init. I am getting the following exception stack:
java.security.AccessControlException: access denied (java.io.FilePermission <path>\user_projects\domains\my_domain\servers\my_ms1\tmp\_WL_user\MyApp\6210pw\war\WEB-INF\lib\_wl_cls_gen.jar read)
at java.security.AccessControlContext.checkPermission(AccessControlConte
xt.java:323)
at java.security.AccessController.checkPermission(AccessController.java:
546)
I am not using a securitymanager explicitlty in my code, as adviced in the book.
Please advise, what's going wrong here.

Java.rmi.NoSuchObjectException: Session has timed out or was invalidated

I am getting error in subject when my application is not using Statefull Session Bean for sometime(20 Minutes or so). What i understand is that after session bean is passivated and next time some method is invoked, it is throwing this exeception. My appserver is Oracle 10gAS release2. Please guide if somebody has any clue...This is very critical.Thanks.
Below is stack trace for reference:

I'm having the same problem. I posted to VSM sample and Pooled ApplicationModule Maximum Inactive Age
which seems to be a similar situation.
Does anyone have any information on where this time out parameter is set on either the app module or OAS and how to handle this error correctly?
Thanks,
Brian

Java.rmi.NoSuchObjectException: RemoteInvokable - id: '272'

We are getting the following error message repeatedly in the app server log file.
java.rmi.NoSuchObjectException: RemoteInvokable - id: '272'
Ultimately, it eats up all space bringing down the server. We have two WLS load balanced in the environment. Any ideas?

Hi,
you probably run into CR071626. Please contact support along with some more from your logfile
and the version you are using.

Java.rmi.NoSuchObjectException

HI all
Can anyone help regrding the following error.
java.rmi.NoSuchObjectException: CORBA OBJECT_NOT_EXIST 9998 Maybe; nested exception is:
INFO: CORE3282: stdout: org.omg.CORBA.OBJECT_NOT_EXIST: vmcid: 0x2000 minor code: 1806 completed: Maybe
I got this exception when I am trying to access the bean.
Thanks in advance..

Hi,
This exception is thrown when you invoke a method on an object that no longer exists in the remote virtual machine.
I think the bean has been removed and hence you get the exception when the client tries to access it.
Seting the log level to fine could help you in getting more detailed exceptions.

Hi..
I guess itzz more of the service pack problems.
Jars built on the later version won't work in the previous version (service packs) of weblogic.
Try building a jar on the oldest version (service pack) u have and then try deploying it to the later version , i think it won't give u any problems.
Try it out and let me know if u face any problems

Weblogic.rmi.internal.LocalServerRefMissing

I am Attempting to serialize and deserialize a stateful session
bean. The deserialization seems to be the problem. I have
figured out that the line throwing the error is the "readObject"
line.
A similar problem was reported on Jan 31 2002, but the solution
suggested deals with the "getEJBObject" line. I have tryed to
implement this solution, as you can see below, but since the
error I am getting is thrown before getting to that line, it
makes no difference.
The Exception I am getting is an "InvalidClassException".
The message reads as follows = "weblogic.rmi.internal.
LocalServerRefMissing no-arg constructor for class".
As far as the "no-arg constructor" error goes, as I understand
it I should not be having that problem. My Session bean
implements the SessionBean interface and does not explicitly
extend anything, so by default it extends Object, right?!
Object has a no-args constructor, so there should be no problem.
My code is as follows:
---SERIALIZATION---
Handle msaHandle = contributions.getHandle();
ObjectOutputStream toFile = new ObjectOutputStream(
new FileOutputStream(handleFile));
toFile.writeObject(msaHandle);
toFile.close();
---DESERIALIZATION---
ObjectInputStream fromFile = new ObjectInputStream(
new FileInputStream(handleFile));
Handle msaHandle = (Handle) fromFile.readObject();
//MsaSession contributions =
(MsaSession) msaHandle.getEJBObject();
MsaSession contributions = (MsaSession) javax.rmi.PortableRemote
Object.narrow(msaHandle.getEJBObject(), MsaSession.class);
fromFile.close();
I have tried to print "classname" (available in the
InvalidClassException class), but only get null as the value.
Anyone have any ideas?

Error when trying to acess a remote bean ??(weblogic.rmi.UnmarshalException

hi,
i have a component (with weblogic 5.1) one one system (say A).
I have an application on other systen (say B) which must connect to that component and insert data in the database.
when i am trying to acces
i get this error...
Exception javax.naming.CommunicationException [Root exception is weblogic.rmi.UnmarshalException: Unmarshalling return

My Bean class Name is TDorderVettingSessionEJB.class in a package com.fn.trading..
when i am running the application on the same system A the code is working. but giving priblem when accessed with system B.
i tried to copy the bean class files in the system B also and kept in classpath..but still it did not work...
