Swing UI Serialization

I wrote a JFrame application with many components, such as JMenuBar, JTabbedPane, JTextArea, JScrollPane, ...
I want to keep the state of the UI ( width, height, location, ... ) every time it exits. So i serialize the whole JFrame instance to a file. And when the application is started again, it will load the serialized file to cast back the instance. There are no exception in the process of serializing the instance.
but when i cast back the instance, it has some problems. I found that the UI Manager seems not working although the size and location are all right. When i resize the frame, the components doesn't rescable according with the size of the frame. Sometimes even javaw.exe will die and Windows ask me to send bug report to Microsoft. But i think it's not the problem of XP.
Does anyone have idea on what the problem i got ?
my platform : WinXP, JDK1.4

I see you are using JDK1.4.

  • Javax.swing.DefaultPopupFactory serialization error

    Hi,
    I get a java.io.NotSerializableException for the class javax.swing.DefaultPopupFactory this seems to be a private class, because I cannot find anything about it.
    The only swing components I am using are some JFrames with buttons, textfields, etc. and a few dialog boxes via JOptionPane.showMessageDialog(...);
    How do I get rid of this error?
    TIA,

  • J2me swing, cdc and window

    my company has developed a working version of swing w/ serializable on the desktop and like to import them into a pda. when i research this option online and i find out that only cdc can do that. however, when i download cdc and it seems that the package is only linux. where can i download a package that can used on window. i need to have swing on the pda, can cdc support all swing component? if not, what other options can i have?? i read online that j2me does not fully support swing, is that true?? i am a new programmer in j2me and really appreciate any help that i can receive.
    many thanks

    First you should be aware that CDC is a configuration, so it does not contain any GUI components. In J2ME there are 3 different Profiles which are based on CDC.
    Foundation Profile (FP), Personal Base Profile (PBP and Personal Profile (PP). Only PP contains enhanced Java GUI elements. But it ONLY contains AWT. SWING is NOT supported and is not part of the PP specification.. Some JVMs like Creme from NSI (http://www.nsicom.com/) support Swing as opptional non-specification package. But you must buy the Creme JVM. The IBM VM J9 supports a reduced version of SWT (a GUI Framework), but not SWING. So generally it is very difficult to use SWING on a PocketPC.

  • Swing + (vs.) Serialization

    Hi!
    Right now I'm working on a Tool for the visual creation of JavaBeans (it's a bit like the BeanBuilder).I use a JFileChooser to choose a file and i tryed to serialize various Swing-Components. The Serialization works without any problems, but after the JFileChooser disappears and the "Main-Frame" trys to repaint i get the following exception:
    java.lang.NullPointerException
    at javax.swing.plaf.basic.BasicTableUI.getPreferredSize(BasicTableUI.jav
    java.lang.NullPointerException
    at javax.swing.plaf.basic.BasicTabbedPaneUI.paint(BasicTabbedPaneUI.java
    :480)
    The really strange thing is, if i just click cancel or close the File-Chooser-Dialog, i don't get this exception i just get it if i click ok.
    Does anyone have a solution for this problem??
    Thanks,
    Chris

    I don't know exaclty why this happens (therefore I need to see more of the code), but maybe (maybe maybe) you're disposing some of the display parts to early? Remember: JFileChoosers should be hidden, not disposed, upon close. Does your code refer to objects contained in the JFileChooser after you approve a choice?

  • Serialize Swing Document - java.io.InvalidClassException

    Hi,
    I'm tryin to serialize a javax.swing.text.Document from a JTextPane (DefaultStyledDocument). This works without problems and I can deserialize it in the same app.
    Unfortunately I'm getting the following error if I try to deserialize it with another app.
    java.io.InvalidClassException: javax.swing.text.DefaultStyledDocument; local class incompatible: stream classdesc serialVersionUID = 940485415728594881, local class serialVersionUID = 940485415728614849The UIDs are always the same above. The data was transmitted over network. The data is valid, both byte arrays in both apps have the same Hash.
    Any help appreciated! :-)
    Best Regards,
    Stephen

    Problem solved!
    It was java.lang.String fault!
    I converted the byte[] array of the serialized object to a String.
    String str = new String( bytearray );and back.
    byte[] array = str.getBytes();Data was corrupted when the String was constructed from the byte array. It is not possible to convert the byte[] array of a serialized object to a string using String() constructor!
    You have to en/decode it with base 64!

  • Problem with writing and reading using serialization

    I am having a problem with writing and reading an object that has another object in it. The purpose of the class is to write a order that has multiple items in it. And there will be several orders. This is for an IB project, where one of the requirements is to utilize a hierarchical composite data structure. That is, it is "one that contains more than one element and at least one of the elements is a composite data structure. Examples are, an array or linked list of records, a record that has one field that is another record, or an array". The code is shown below:
    The error produced is

  • Domain design causing full object graph serialization

    Hello,
    I work on a project, based on 3-layer-architecture. We have rich client developed on swing, application server and we persist our domain objects in the database.
    We map the domain objects using hibernate, send the same objects (means, we use POJOs and don't use DTO) via spring from application server to the server and visa versa in case the objects are to be saved, deleted etc.
    We use an object identity store on the client side, in which all already loaded objects are stored.
    My challenge is as follows:
    - Since an object is stored in the object store, the same certain object is used in every GUI module. Imagine, we have customer, account and a list of transactions per account. In practice, let's say:
    1 customer
    2 accounts
    1000 transactions per account which ever exist
    - In one of the modules, the used loaded all list of transactions. So, at that moment, 1 customer object, 2 accounts and 2000 transaction objects are bound to each other via java references (object graph).
    - On another module, the user wants to edit a very small attribute of customer object, say he corrects his birthday date and saves it.
    - Saving operation sends the customer object to the server. But the problem is, a very big object graph hangs on this one little customer object and are serialized to the server, although the
    service.save(customer);is called, and this costs extremely much time for our application.
    boldSOLUTION:*bold* We solved the problem with a hack, as we used the serialization over XStream framework from Thoughtworks in xml-format. We could set a cut in the serialization and have serialized only the customer object for that use case.
    So the problem for the save-use case was solved. This has a disadventage: the loading time (server-client (de-)serialization) using xml is longer than the java standard, especially remarkable if you load a big number of objects.
    I've read many articles about the enterprise architectures which are related to domain objects, dto, serialization. It is not uncommon to avoid DTOs and use POJOs on the server and client as well, if the domain objects don't contain business logic. So, I just wonder, how the problem above should be solved smartly, if the non-DTO, say POJO alternative is chosen.
    I appreciate your opinions.
    I hope my question is not too long. Thanks in advance,
    A sample code:
    (The concrete case in our application requires the navigability from customer to account)
    public class Customer implements Serializable {
         private Set<Account> acounts = new HashSet<Account>();
         // Getters, setters
    public class Account implements Serializable {
         private Set<AccTransaction> acounts = new HashSet<AccTransaction>();
         // Getters, setters
    public class AccTransaction implements Serializable {
         private String operation;
         private Timestamp timestamp;
         // Getters, setters
    }Alper

    Thanks for the quick answer.
    The numbers are just wildly guesses, in order to keep the sample simple.
    Actually we develop a system for automobile industry. So, instead of customer, you may think of a company, like Ford. Account would be then Fiesta. Instead of AccTransaction we may think a huge number of car pieces (clima, motor, radio, etc.).
    So hierarchically we have
    Company (Ford, Opel, etc)
    Model (Fiesta, Astra, etc.)
    Piece (1000 pieces per model, so Fiesta, Opel have 1000 different pieces each)
    The problem is, if I loaded the Ford->Fiesta->1000x pieces for one view and then switch to another view. In the second view, I rename Fiesta to Fiesta II, and want to save this renaming operation using:
    What exactly does that represent?
    If you want to rename an existing car then you need logic to do exactly that. You do not copy the entire tree.
    If however you do want to copy the entire tree then that is in fact what you must do. Although I seriously doubt that there is a valid business requirement for that. In terms of efficiency though you could write a proc that did that rather than propogating the tree.
    Although further if you do in fact have two cars which use the same inventory item(s) then, again, you do not copy the entire tree because you are not creating a brand new inventory item. Instead you should only be pointing to an existing item.
    I wonder how this problem is solved smartly, if you guys share domain objects between the client and server, and avoid DTO.The first step is to start with actual business requirements.

  • Converting swing components into some readable format

    Hello all,
    A requirement for the application I'm writing is for it to email automatically generated reports to various clients. My problem is that I'm not sure what would be the best format to send the reports. The reports are attached to the email and the sent via JavaMail.
    I have 2 modes of thought at this stage:
    1. Convert a Report (Printable Swing component) to HTML and either attach this or embed it in an email. Question here is how do I convert the Report to HTML?
    2. Print the Report using Adobe Distiller. Once the pdf is created, attach it to the email and send. Problem is that it's unlikely that other users of my software have Distiller. Any Swing to PDF packages that anyone knows of?
    To give you some idea of exactly what I'm doing, please look at the following 2 links.
    1. A screen shot of the Report:
    http://www.genepi.waimr.uwa.edu.au/radar/storage/report.jpg
    2. The Report after it's been printed with Distiller:
    http://www.genepi.waimr.uwa.edu.au/radar/storage/report.pdf
    Note: The previous files will be removed from the server in a couple of days.
    Also, I'm open to any other suggestion! So if anyone has a good idea, please post it!
    Thanks,
    Muel.

    Thanks for your reply.No problem. Interesting problem, as a matter of fact.
    Those reports are created dynamically from querying a
    database. A Report itself is a JDialog, the
    content-pane of which uses a custom LayoutManager.
    The LayoutManager controls a Book and decides whether
    or not to add JLabels to the current ReportPage (a
    Printable JPanel), or to create a new ReportPage and
    add them to it.This is where I don't quite agree with your approach. I don't know if you're familiar with the MVC concept because this is typically the issue you're dealing with here. I hope I'm not misinterpreting what you said but it seems you are storing the content of your database query directly in a particular View (a violation of the MVC principle).
    What you need to do is create a true Model which will hold the logic of what your Reports really are. From what I understood with your image, this class should contain member variables such as addresses, a title, funny notes ;) ...
    Displaying your report in a JDialog is all about creating the most appropriate View for that Model. Using a custom document with its own LayoutManager, JLabels... is, IMHO, a very pragmatic, convenient choice. It is not the only possible choice however. What if, in the future, you wanted to allow the user to copy / paste the report outside your application ? What if, you wanted to allow him/her to edit it prior to printing it?
    Your other requirements involve a printable version of your report and one that can be sent by email. It turns out that HTML is a good pick. Personally, I once had to print HTML and the advices I found at http://www.fawcette.com/javapro/2002_12/online/print_kgauthier_12_10_02/ were quite precious (paging is nicely handled). Moreover, sending html in a mail is piece of cake.
    All it comes down to is how to produce that HTML. Forget about my suggestion of creating a StyledDocument. It might work but writing HTML directly is much faster and easier. The only real constraint here is that the produced HTML should be 3.2 valid. In your case, this serialization should be conducted on the Model, NOT on the View.
    I forgot to mention that once you'll have produced that "html report writer" class, you'll have to reconsider using a JTextPane for your Report display JDialog.

  • The Problem in serialization.

    The serialization issue is a trivial one at the moment. However the threat of a version change is imminent considering the next release of JDK 6 "Mustang" may have considerable improvements especially on the Swing side. Therefore, I strongly encourage you to write your own code to persist the tree data into a file. Such a logic is much preferable as it will over-come the issues with serialization.
    The main problem with a version change is that every serializable class uses a special random number stored in a private static field called serialVersionUID. So when the serializable class is serialized, this number is also persisted to the serialized form.
    When the object is de-serialized, the number is also deserialized. Java checks the de-serialized number against the serialVersionUID field of the class and verifies if the two match. If they do, it means that the deserialized data is in the right format of the class. If they differ, a InvalidClassException is thrown. Every new version of the class changes this unique number. Hence an object serialized with an older version of the class will not be allowed to be de-serialized by a new version of that class and vice-versa.
    This mechanism allows developers to version their new releases and ensures that serialization and deserialization operations remain consistent across multiple-versions and prevent invalid state of the object.

    The serialization issue is a trivial one at the moment. However the threat of a version change is imminent considering the next release of JDK 6 "Mustang" may have considerable improvements especially on the Swing side.Don't make statements like this unless you know what you're talking about. Do you know that Sun's JDK release policies prevent them from doing that in the middle of a release? and that they haven't done such a thing in 13 years? Do you have any actual evidence that they are going to change serialVersionUIDs in the middle of a release?
    Therefore, I strongly encourage you to write your own code to persist the tree data into a file.
    I would strongly encourage developers not to use Serialization on Swing objects at all, which curiously enough is what the Javadoc has been saying for ten years. You should use java.beans.XMLEncoder for this. That's what it is for.
    Such a logic is much preferable as it will over-come the issues with serialization.Home-grown code is never preferable to what is provided in the JDK.
    The main problem with a version change is that every serializable class uses a special random number stored in a private static field called serialVersionUID.That's not a 'problem'. That's part of the solution.
    Every new version of the class changes this unique number.Only if you don't declare your own static final long serialVersionUID.
    This mechanism allows developers to version their new releases and ensures that serialization and deserialization operations remain consistent across multiple-versions and prevent invalid state of the object.Exactly. I suggest you read the Versioning section of the Serialization specification before posting again on this topic, and also read up on Long Term Persistence in Java Beans. You have much of this information back to front, and you don't appear to have heard of either defining your own serialVersionUID or Long Term Persistence.
    And your claim that Sun will change serialVersionUIDs in the middle of Java release 6 is just ludicrous.

  • Rendering of Swing components

    Hi,
    As the renderer is used to be client independant, is it suitable to send back to the client a serialized view of Swing components (using the new XML serialization format) ?
    This could allow server-side management of the client's look-and-feel and total move of the business on the server.
    It might sounds weird and I'm not totally clear with myself anyway.
    I think a little "deamon" should handle the requests to the server and the demarshalling step of the server response.
    Any point of view on this ?
    (this is just a thought of an alternative use of the renderer capabilities coz todays it only sends back HTML tags)

    Hi,
    personally, I do not have too much experience with Swing.
    There is a project on sourceforge that implements your idea but is not based on Java Server Faces.
    It's called SwingML:

  • Using swing to develop EJB project

    Hi, Folks
    I am using jbuilder7 to develop swing connect to ejb project, one requirement is that i should doing control with the editable table. That requirement make me to tied with JBuilder component JDBTable. However the development time would become remarkable long. does anybody have experience of using fancy swing and EJB in the same project?
    thansk in advance.

    forget to tell you I am using JDBTable already. the problem is that how
    could i serlize the dataset to EJB in a easy way? ok, you don't need to serialize your dataset to trasmit to server side. Class com.borland.dx.dataset.DataSetData implements Serializable interface already, so you can send your dataset to server and do not care about serialization. But what to do with this DataSet on server side is very interesting question ;). As for me, it's not very handly to pull out your data from Dataset on server side (DataSet "looks" like client-side class). But, of course, it's up to you.
    unfortunlly I should doing add, delete, edit from my table. So its
    pretty complex to deal with this sort of issue.Why complex? I don't think so. For example, you may set 2 buttons: "Set" and "Delete" under your Jtable view and just "to fish" data client entered in your Jtable string, pack this data in your own serializable model and send this data to server session facade. As for me that's very handly and fast. And there is no complexity...
    Regards.

  • RMI Callback after serialization in Weblogic 10.3

    I have an application with a JRE1.6 Swing client and a J2EE server running on weblogic 10.3 (JRE1.6)
    For certain operations the server does a RMI Call back to the swing client. So the RMI Object(UpdateListener) is passed to the server during the business call.
    public interface UpdateListener extends java.rmi.Remote{
         void update(int action, Object data) throws RemoteException;
    My client class implements the this interface to get the CallBack. The problem is that, after reaching the server when i persist and read back the RMI Object from database, i'm unable to do the callback. The stacktrace is
    java.rmi.ConnectException: Could not establish a connection with 4079602057493999578C:192.168.7.20R:4131263118401458263S:127.0.0.1:[7001,7001,-1,-1,-1,-1,-1]:domain:Admin_Server, java.rmi.ConnectException: Destination is not a server; No available router to destination; nested exception is:

         at com.ibsplc.iaviation.utility.realtime.CallBack_1030_WLStub.update(Unknown Source)
    When i do the callback before persisting, the callback is working. I thing it is some thing to do with the serialization and WEblogic.
    I'm pasting sample code.
    //Server method
    public void doBusiness(UpdateListener rmiObject, String status) {
         //This call works fine and i get the callback in client
         try {          
              rmiObject.update(0, "Direct CallBack is working");
         }catch(IOException ioe) {
              ioe.printStackTrace();
         //This call doesnot work and i get the exception stacktrace above.
         //This call was working fine in Weblogic 8.1 (JDK1.4)
         try {
              ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
              ObjectOutputStream os = new ObjectOutputStream(byteStream);
              os.flush();
              os.writeObject(rmiObject);
              os.flush();
              byte[] byteArrayOfData = byteStream.toByteArray();
              os.close();
              ObjectInputStream in1 = new ObjectInputStream(new ByteArrayInputStream(byteArrayOfData));
              UpdateListener rmiObjectAfterSerialze = (UpdateListener) in1.readObject();
              System.out.println("Trying call after after serlialze");
              rmiObjectAfterSerialze.update(0, "This call is not working");
         }catch(IOException ioe) {
              ioe.printStackTrace();
    Is this something to do with Weblogic10.3? Do i have to do something to reactivate the rmiObject after serialize and deserialize?
    I had posted this in core java forum and was suggested to post in weblogic forum.
    http://forums.sun.com/thread.jspa?threadID=5436290
    Any help is greatly appreciated.
    Thanks

    I agree with that and we have removed this kind of callback the new version of the application. But the old version is still being used and had to be recently migrated to weblogic10.3, that is when the issue popped up.
    I have made the client implementation class Activatable. The code is pasted below. But still the issue persists. Do i have to do something else after deserialization to activate the stub class?
    public class CallBack extends Activatable implements UpdateListener {
        public CallBack(CallBackListener callBackListener) throws RemoteException{
         super(null,0);
        public void update(int activity, Object data) throws java.rmi.RemoteException {
            System.out.println("CallBack Reached");
    }

  • Created serializable object, but get "Class not found" on "createObjectMessage()" cal

    I'm using OC4J 9.0.2.1 and JDeveloper 9.0.2 with Oracle db. I have a set of queues created in the database.
    Before I try to send my request, I create an instance of the serializable object I want to send. I do all of my queue connection setup, then I call:
    queueSession.createObjectMessage(request);
    Where "queueSession" is a QueueSession obtained from "queueConnection.createQueueSession()".
    When I step over this function call, I get the following:
    oracle.jms.AQjmsException: JMS-109: Class not found: com.attws.it.bsa.felix.mci.common.ServiceInfoRequest
    (The indicated class name is the type of the "request" object.)
    What could I be doing wrong?

    The code below creates the following classes when I compile it (using jsk1.3):
    DistanceBarApplication2.class
    DistanceBarApplication2$1
    DistanceBarApplication2$2

  • Serialization of JTable

    Hi,
    we encounter some exceptions trying to serialize a JTable to XML:
    java.lang.NoSuchMethodException: javax.swing.plaf.basic.BasicTableUI$PropertyChangeHandler.<init>()
         at java.lang.Class.getConstructor0(Class.java:1930)
    We already patched the PropertyChangeHandler and gave it a default C'tor, but this would not work either. (Obviously inner classes make some problems here...)
    Does anyone have an idea what this comes from?
    Does anyone encounter similar problems?
    Thanks,
    Mauritius.

    Hi,
    we do not have any data in the table, except the names of the columns in the TableHeader. This is for a GUI editor, where only the properties of the JTable shall be edited.
    We are some steps further in seeking the problem, but still haven't found a solution:
    We try to serialize a JScrollPane containing a JTable. If you write an example that just creates the two and saves them to XML, this works fine. But if you add a Button to your application triggering an action which then saves the XML file, the described exceptions are thrown. If you leave the JScrollPane around the JTable away in the latter case, it also works.
    Our solution will probably be to write the JTable contained in a JScrollPane individually, storing only the JTable, as this works. When loading the file again and a JTable is found, a JScrollPane will be put around it. This is not satisfying, but should work.
    Greetings,
    Mauritius.

  • Serialization vs xmlencoder bean

    Hi,
    I would like to be able to save/load a DefaultTreeModel object from file.
    However the Java 5 api contains this warning for all Swing components.
    Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.
    So is XMLEncoder the only longterm option for saving Swing objects?
    Also do the objects I encode have to be Java beans?
    So is it recommended I use XMLEncoder for Swing objects and Java serialization other objects?
    Regards,
    Nikolas.

    A look into the API docs for XMLEncoder will give you a sample example of how to use it.
