JTabbedPane and Serialization

Hi, I want to Serialize a JTabbedPane to a file but I am experiencing lots of problems :
Firstly, I get an exception :
java.io.NotSerializableException: javax.swing.plaf.basic.BasicTabbedPaneUI$MouseHandler
I can override this in out custom plaf, but then this throws out pluggable look and feel. Is there any other way I can fix this ....
Also I have had to change lots of code to get these to Serialize e.g cutomizing the BasicTabbedPaneUI and other classes to implement Serializable, and I get a bizarre problem where I write my Swing JxInternalFrame to disk, and then when I goto dispose of it, it throws a completely different Exception in firePropertyChanged within JTabbedPane.
It tries to cast a JTabbedPane within the class BasicTabbedPaneUI$PropertyChangeHandler and the source is a Viewport... If I remove the Serialize to Disk code, then this does not occur!
I am a little baffled why this happens ... can anyone help?

My objective is to Serialize out the JxInternalFrame with all it's components to disk.
We have an Application that Dynamically creates GUI interfaces using XML. Instead of creating the JxInternalFrame and all its components from the XML String, I thought it would be quicker to Serialize the Object to disk and re-read once the Frame once it had initialliy been built, for caching purposes.
It takes about 4 seconds to build a 6MB JxInternalFrame with all its components (JTabbedPanes, JTextFields, JCombos etc....), and I want to minimise this to be almost instant ... i.e as if using JInternalFrame.setVisible( true or false ).
I have not looked at XMLEncoder/Decoder yet, I will have a look and see if this will help or if this is fast enough.
Bare in mind I could be opening a Screen many times, but do not want to initiate it again from raw XML AND I do not want to store Huge objects in memory.

JTabbedPane and InsertTab method

Hi at all!!!Sorry for my bad english!!
For a university project I want to implement a copy of notepad. Only I want to manage a more document and I think that it is possible through the JTabbedPane and it works.
But I don't know how I can implement a button that add/remove a tab during the runtime.
Is there someone that can help me???
thank u
giuliano

Your main window should have [AddNewTab] and [RemoveTab] buttons.
In their event handler, launch a dialog and accept required user inputs.
After you dispose the dialog, call JTabbedPane#add(), addTab() or remove().

JTabbedPane and removeTabAt() method

Hello,
I use in my application a JTabbedPane and i want allow the user to remove a tab of this JTabbedPane. When the JTabbedPane change i need to perform some traitement.
So i use a ChangeListener to be informed of all changes of my JTabbedPane.
But, when i removed a tab which is not in last or first position i'm not informed by the change.
Thanks for your help.
Guiguch

I had the same problem. I fixed it by overriding the remove() method to fire a StateChanged event:
tabbedPane = new JTabbedPane()
     public void remove(int tab)
          super.remove( tab );
          int after = getSelectedIndex();
          // The selected tab remained the same after this remove, consider
          // it a state changed
          if (after == tab)
               fireStateChanged();
};

Drag and Drop questions and Serialization in the 1Z0-852 Upgrade exam?

Hi,
Does anyone know if the drag and drop items and serialization have been removed from the 1Z0-852 Java SE 6 Programmer Certified Professional UPGRADE exam?
I know that they have been removed from the 1Z0-851, but not sure about the upgrade exam.
Thanks in advance,
Alvaro

Marshall and Serialization

Hello There:
Can any one please educate me the difference between marshaling an object and serialize an object. They looked the same to me. they both flat the object to a readable format and maintain the state of the object. What's the difference, why both terms are used. Where do I find the definition of 'marshal'? Thank you very much!

Entry processor performance and serialization

Our application invokes an entry processor from a .Net extend client. We are seeing very poor performance the first few times the processor is invoked (typically 60ms vs 2ms). I was expecting this to be due to the overhead of the initial TCP connection but this doesn't appear to be the case. Here is a typical set of timings from the beginning of invoking the EP on the client:
5ms: Object starts being deserialized on proxy
7ms: Deserialization is finished, and serialization begins
9ms: Serialization is complete.
55ms: Deserialization begins on the storage node
58ms: Deserialization complete on storage node
58.5: Entry processor invocation complete
60ms: Serialization of result is complete
My questions are:
- What is happening between the end of serialization of the object by the proxy and deserialization starting on the storage node?
- Given that the cache is POF enabled, why is the proxy deserializing and reserializing the entry processor?
Version is 3.7.1.6

Hi Rob,
Config is below. defer-key-association-check is not set. The timings were established by logging the POF serialization in each process so its definitely the proxy that is doing it.
Regards,
Dave

JTabbedPane and focus problem.

Hello. I currently have a JTabbedPane which contains the various panels that make up different tabs. These tabs are extensions of panels, and are seperate classes imported into the class which contains my JTabbedPane and then added. The frame which conatins my JTabbedPane also has a button, which when pressed I wish it to look at the tab which is currently active, and call a method from the class which this tab refers to. The problem is that I don't know how to get my button to determine which tab is currently active. Any help will be gratefully recieved.

Use getSelectedComponent() or getSelectedIndex() of your JTabbedPane object.

JTabbedPane and one Button for all Tabs

Hello everybody,
im new here an would say HELLOOO to everyone
So ive got an issue.
I am creating in "class A" tabs for a JTabbedPane. In "class B" i create the JTabbedPane and creat instances of class A and add them to the TabbedPane.
in Class B i also create a button, for save actions. When i click the button, a method "save()" will be called and read from every tab the Strings out of textfields.
My problem now is, that it dont work, i call the save method with the instance from the tab, but it dont getText() from the textfield.
For example:
//create an instance tab, parameter is the save file
Tab myTab = new Tab(file);
//other code
(Tab)myTab.save(); //here i eclipse cast to Tab automatically
the save-Method in class A (Tab):
save() {
sysout(texfield1.getText)
BTW how can i highlight code in this forum?

You can add syntax highlighting by going into the advanced editor, that will add a button for it. Unfortunately there are no quick code tags :/
After you find the button post your ACTUAL code. not just some random snippet which looks like your code. What you posted doesn't even compile.

JTabbedPane, and JPanel.

Hi im going thrue swing tutorials here on sun. And wonder a bit about hierarchy. I use JTabbedPane and every class have there own JPanel that i add to the extended JPanel. I show below with example.
In Main class
public JFrame mstFrame() {
        JFrame frame = new JFrame("Main Frame");
        JTabbedPane mstPane = new JTabbedPane();
        mstPane.addTab("Start", new StartPage());
        frame.add(mstPane);
        frame.setVisible(true);
        return frame;
    }In StartPage Class
public class StartPage extends JPanel {
    JPanel createProjectPanel = new JPanel(new GridBagLayout());
     GridBagConstraints c = new GridBagConstraints();
     JScrollPane createCustomerPane = new JScrollPane();
     c.gridy = 1; // second row
     c.gridx = 0; // first cell
     createProjectPanel.add(createCustomerPane ,c);
add(createProjectPanel);Does this destory the hierarchy, or is it okey to do it this way?

It makes sense to have each tab represented by a panel, so I don't reallly understand the question.
public class StartPage extends JPanel
    JPanel createProjectPanel = new JPanel(new GridBagLayout());
    add( createProjectPanel );However, it is unecessary to create a second panel since your class already extends JPanel. Just add the scrollPane directly to the class.
setLayout( new GridBagLayout() ):
JScrollPane createCustomerPane = new JScrollPane();
add(createCustomerPane, c);

Comparable and Serializable Interfaces in MIDP

Hi All,
I have developed a program in java which implements Comparable and Serializable Interfaces. After, I decided to run the program in J2ME. But later on, I found that MIDP doesn't implement these interfaces.
Some one can help me how to implement my own interfaces.
Thank you

Thank you for replying to me.
My problem is to compare to objects in MIDP.
You know that in java is possible to implements directly the Comparable interface but in MIDP is not the same. So I think it requires to create your own. Is that my question.
I need some to help me. just to avoid the implentation of comparable interface from the java lang package.
Thank u.

What is serialization and serializable

what is serialization and serializable,Can any body explain me please.

hi
Serialization in java is the process of making the object flat which can later be stored on your disk like a normal flat file. the serailized object can be found useful mainly when using RMI and EJB where we persist cobjects so that they can be sent online (thru cable) by this we mean for objects to be distributed the prerequiste is tht they should be serialized. For this we have a interfacein java called "Serializable". the class tht needs serialization of its object should implement this class. this is a marker interface(the interface tht contains nmo methods)
hope the concept is clear if not please mail me to : [email protected]
bye
thnx and regards

Hi, i have a problem with a web application that is running on an Application server (BEA WebLogic 7.0). I have only the war file of the web application and i must know if in this war there is a class that is not serializable.
How can i find it ? Is there a tool that can help me to find not serializable classes ?
Thanks.

One way to do that is to decompile Java classes with Java decompiler and see which one doesn't implement Serializable interface. Here is a link to a good decompiler: http://www.kpdus.com/jad.html
