        ... 3 moreI checked all the code but the objects I use are instantiated from Serializable classes.
I read something about "java.util.RandomAccessSubList" but what is this? I use List and Map.
Are there problem with the List and the Map I use?
Could someone help me?
Thanks, bye bye.

You have a List member whose value is derived from List.subList(), which is implemented by the class named in the exception, which isn't serializable. Change it to
subList = new LinkedList<T>(list.subList());where T is whatever it should be.
You should do this anyway, as the subList is merely a view of the original list, so if it was serializable it would take the entire original list with it.

    Hi I think you are using the method elements() in a remote method.
    This method can't be Serializable!! Because it returns an Interface. Interfaces are never Serializable.

  • Java.io.NotSerializableException: java.util.Vector$1

    I am using Java 2 in the API it says that the Vector implements Serializable but I am getting an exception java.io.NotSerializableException: java.util.Vector$1 I don't know why please help.
    Thank you
    palanisr

    Although Vectors are Serializable that doesn't mean that the contents of a Vector are necessarily Serializable. What are the contents of your Vector? Are they objects of a Serializable class? If not that is your problem. The attached sample code demonstrates the problem of serializing a Vector that contains non-serializable data. If you make the Employee class Serializable the code works.
    import java.util.*;
    import java.io.*;
    public class Serialize
    public static void main(String args[])
      ObjectOutputStream oos = null;
      FileOutputStream fos = null;
      Vector v = new Vector();
      v.add(new Employee("Smith","John"));
      v.add(new Employee("Jones","Albert"));
      try
       fos = new FileOutputStream("vector.ser");
       oos = new ObjectOutputStream(fos);
       oos.writeObject(v);
      catch(FileNotFoundException fnfe)
       fnfe.printStackTrace();
      catch(IOException ioe)
       ioe.printStackTrace();
      finally
       try
        if (oos != null)
         oos.close();
       catch(IOException ioe)
       try
        if (fos != null)
         fos.close();
       catch(IOException ioe)
    class Employee //implements Serializable
    private String lastName;
    private String firstName;
    public Employee(String lastName, String firstName)
      this.lastName = lastName;

  • Java.io.NotSerializableException: java.awt.BasicStroke - really confusing

    I have a class Box which has two member Size and Location, both Serializable.
    Then I have several classes (e.g. Node) which extend Box.
    None of all the classes (Box, Size, Location and all extensions of Box e.g. Node) use BasicStroke. I commented out the import of BasicStroke in all classes that are Serializable, so it cannot be used anywhere.
    The problem is I use drag and drop, and when Box is also Serializable I get the following error when trying to drop:

    I do not know how to better describe the error, because I have no clue why BasicStrokes is tried to serialize at all. I am really confused, but perhaps somebody has seen something similar and can give a hint.

    Thanks for the hint. Actually I must say once more that I was too tired that I have overseen a memeber field because of bad code layout :-( I better went to sleep...
    But there is still something confusing, that is also the reason why I did not search for the fields in the right class.
    So I have a class Box and a class Node which extends Box. Node is the one which contains the evil AWT references. When I declare only Node as Serializable, it works. But when I also declare the super class Box as Serializable the error occured.
    In my opinion a Serializable sub class with a super class which does not implement Serializable does not make sence, but as an accident I did it. What is the semantic in such a case? (At least I know it could not serialize the sub class as expected...)

  • Java.io.NotSerializableException: java.util.Hashtable$KeySet

    Hi,
    i have a
        private Hashtable<IDInterface, String> globalPeerFarmMap_=new Hashtable<IDInterface,String>();    in one class and it can be serialized OK.
    In another class, however i have a     private Hashtable<IDInterface, PeerBasic> thesePeers_=new Hashtable<IDInterface, PeerBasic>();     and a java.io.NotSerializableException is thrown - on the KeySet it seems.
    However, ID (which implements IDInterface) is serializable (and all its fields are serializable) and it works in the first case.
    Any ideas? Didn't want to be confusing, but if simplistic i will post some code.
    Thanks

    Found it. The compiler didn't provice much info. Somewhere inside PeerBasic, i call keySet on a Hashtable. I don't understand why this cause a problem.

    this is coming  when i m accessing this method:
    class BallServerImpl extends UnicastRemoteObject
    implements BallServer
    * @return an enumeration of all Balls as proxy objects
    public Ball[] getAllBallProxies() throws java.rmi.RemoteException
         Ball[] locations1 = new Ball[hash.size()];
    java.util.Enumeration iter = hash.elements();

    while (iter.hasMoreElements())
         BallImpl impl = (BallImpl)iter.nextElement();
    locations1[idx++] = new BallProxy(impl);
    return locations1;
    why this function is running fine when i m calling this from client unlike getAllBallProxies() nevertheless both are returning the same thing:
    * @return an enumeration of all Balls as remote references
    public Ball[] getAllBalls()
         Ball[] locations = new Ball[hash.size()];
    java.util.Enumeration iter = hash.elements();
    int idx = 0;
    while (iter.hasMoreElements())
    locations[idx++] = (Ball)iter.nextElement();
    return locations;
    the proxy Class:
    * The Proxybouncing ball.
    public class BallProxy implements Serializable,Ball {
    * The Real bouncing ball.
    public class BallImpl extends UnicastRemoteObject implements IBallRemote,Serializable

    that there was some thread there in BallProxy but i removed all from them and now testingIf you don't post the code people ask to see, you may never get a useful answer here.
    P.S i didn't know that threads are not SerializedThe Thread class is not Serializable. Precision please.
    Now i m updating the code, i needed the confirmationConfirmation of what?
    and now trying to avoid them.Them?
    But what if i need them.Them?
    Please make the effort to express yourself clearly. You've already been told you're not making much sense and you haven't done anything about it.
    how can we make serialized?The concept of serializing a Thread makes no sense whatsoever. You don't want to do it. You don't need to do it. You can't do it. It wouldn't work if you could do it.
    Somewhere or other you have a class member that is a reference to a Thread. Remove it or make it transient. If you post the code somebody may help you. If you don't, nobody can possibly do that.

  • Java.io.NotSerializableException

    I am running iplanet ias 6.0 sp3 with web server 6.0 sp1. I
    successfully deployed an ear file that contains the war and the jar to
    the APPS dir. The session ejbs and the entity ejbs are packed into the
    jar file which are deployed with the ear.
    I have two piece of testing code. One is a standalone java program.
    The other one is a jsp page together with the jsp bean which are packed
    into the war file in the ear. The jsp bean code and the standalone
    program are doing the same thing. They call a session ejb which calls an
    entity bean.
    I have made 2 experiments
    1> Start server, run the standalone test, got the correct result.
    Then run the jsp from the browser, got the correct result.
    2> Start server, run the jsp from the browser, fail to get the
    result. run the standalone test, fail to get the result
    The paten is very consistent. The code and the error msg for test 2 are
    attached. Could any one tell me what might cause the problem in the
    second test and how to resolve the it ?
    Thank in advance

    When the test fails, I got the following error msg from the console.

    Xiao,
    We have the same problem.
    The reason why your stand alone works, but your browser based doesn't,
    is because the iPlanet Application server requires that all EJBs, all
    objects held in any EJB, all objects held in attributes in an
    HttpSession, and all objects held in those objects MUST implement
    java.io.Serializable.
    The unfortunate reason why iPlanet does this is because iPlanet does not
    preserve the state of objects in memory across hits to the server.
    iPlanet serializes each and every object mentioned above when the HTML
    is returned to the client, and then un-serializes all the objects again
    when it receives another hit from the client. This is true even in the
    case of no-dsync sticky load balancing.
    This is ridiculous. We use sticky load balancing and we have many
    objects stored in HttpSession attributes which we do not want to be
    serialized every hit to the server, in the interest of speed. It takes
    too long to serialize all the objects, and it would take way too long to
    save them in a database every hit.

    I am running iplanet ias 6.0 sp3 with web server 6.0 sp1. I
    successfully deployed an ear file that contains the war and the jar to

    jar file which are deployed with the ear.
    I have two piece of testing code. One is a standalone java program.
    The other one is a jsp page together with the jsp bean which are packed
    into the war file in the ear. The jsp bean code and the standalone
    program are doing the same thing. They call a session ejb which calls an
    entity bean.
    I have made 2 experiments
    1> Start server, run the standalone test, got the correct result.
    Then run the jsp from the browser, got the correct result.
    2> Start server, run the jsp from the browser, fail to get the
    result. run the standalone test, fail to get the result
    The paten is very consistent. The code and the error msg for test 2 are
    attached. Could any one tell me what might cause the problem in the
    second test and how to resolve the it ?
    Thank in advance

    When the test fails, I got the following error msg from the console.

  • Java.io.NotSerializableException in WL6

    All,
              I have a servlet calling a user/group manager stateless session bean.
              The same code works well in WL5.1.0.
              Recently I migrated to WL6 and found there is a serialization problem.
              Rebuild the EJB jar with WL6 ejb
              compiler did not solve the problem. Here is the detail:
              In the remote interface I have a method called assignGroups().
              public interface InfUserGroupManager extends EJBObject {
              public void assignGroups(InfIIPSession session, InfDBObjectPK userPk,
              Collection groupIds)
              throws RemoteException, InfInsufficientPrivilegeException;
              In a servlet I have code like this:
              InfUserGroupManager mgr = ....; // Gets a reference to InfUserGroupManager
              stateless session bean.
              HashMap groups = .....; // Both keys and values are java.lang.Integer
              objects.
              Collection assignedGroups = groups.values();
              mgr.assignGroups(iipSession, userPk, assignedGroups);
              java.util.HashMap and java.lang.Integer are both serializable. However, when
              trying to invoke the
              assignGroups() method on the InfUserGroupManager object will raise
              exception.

  • Java.io.NotSerializableException Problem

    I am getting the following exception when trying to serialize a Stack of objects.
    java.io.NotSerializableException: java.lang.reflect.Method
    The objects that I am trying to serialize already implements serializable.
    What could be the problem?

    The problem is that java.lang.Method is not serializable and some class somewhere has a non-static non-transient reference to a Method.

  • Java.io.NotSerializableException when overwrite the JTable data into .txt file

    hi everyone
    this is my first time to get help from sun forums
    i had java.io.NotSerializableException: java.lang.reflect.Constructor error when overwrite the JTable data into .txt file.
    At the beginning, the code will be generate successfully and the jtable will be showing out with the data that been save in the studio1.txt previously,
    but after i edit the data at the JTable, and when i trying to click the save button, the error had been showing out and i cannot succeed to save the JTable with the latest data.
    After this error, the code can't be run again and i had to copy the studio1.txt again to let the code run 1 more time.
    I hope i can get any solution at here and this will be very useful for me.
    the following is my code...some of it i create it with the GUI netbean
    but i dunno how to attach my .txt file with this forum
    did anyone need the .txt file?
    this is the code that suspect maybe some error here

            }i had found a new thing that when i just double click the cell without change any data inside the table
    and click the button "Save". the same exception which is
    java.io.NotSerializableException: java.lang.reflect.Constructor
    will come out again.

  • Java.io.NotSerializableException: com.tangosol.util.internal.ConcurrentCoun

    Hi,
    I am working on a small prototyep project trying to understand how coherence works.
    I have a object that creates an instance of entry processor and invokes the cache. I get following error. Entry processor is serializable - the app can write an instance of EP into a file.
    Using same setup if I merely call put() it works fine for me.
    Any idea what coherence is doing here ?
    Thanks

    The problem is fixed.
    In my EP, process() was returning "entry" instead of modified object. Comparing my code with some other samples helped me.
    So it is all down to my mistake.

  • Java.io.NotSerializableException error when starting 8.1 app server

    I am running JES 054Q with uwc deployed on the app server 8.1 (along with am, portal, and da). I am getting a java.io.NotSerializableException for com.sun.uwc.common.util.UWCPreferences when the application server starts.

    I think this might occur if you don't have the patch for SunAlert 46042 installed. There's more information on this critical Solaris security vulnerability, which was reported back in 2002, at http://sunsolve.central.sun.com/search/document.do?assetkey=1-26-46042-1
    Can you run the following command to check if you have patch 109326-09 installed and let us know the result?showrev -p | grep 109326If you don't have 109326-09 or higher installed, you should install it as soon as possible. You can follow the link from the SunAlert. Better yet, install the latest Solaris 8 recommended patch cluster from http://sunsolve.sun.com/pub-cgi/show.pl?target=patches/patch-access to make sure your system is fully patched and up to date.

  • Java.io.NotSerializableException when using POF over Extend

    I changed a class to use POF and it seems to work fine among TCMP cluster members but when apps connect with Extend I get an exception indicating that maybe either the extend proxy or client app is not correctly configured to use POF.

    Looks like I spoke too soon. Moving the <serializer> to the correct location in the Extend client XML config did fix the problem I was seeing but it created a new problem. It appears the Extend client wants to use POF for everything including non-POF services like the one handling the Serializable (non-POF) object oms.Order. That's what I gather from this exception
