    Angry Can't get it to save stuff with JFileChooser

    I don't know how to get the FileWriter to get the text typed in the file name area in the JFileChooser, and it never saves the file, or, if it does, it doesn't save anything and the file keeps getting blank. How do you get it to save the background and the text in the Background and everything?

    I don't know how to get it to save it so if I created a java database sorta thing with a JTable, it could be saved and keep the text in the tables there, instead of losing it, while loaded, and it would save.

    How do I do that?

     * End Date:  
     * Project Title: Church Hymn Book Program
     * Description: Uses JComboBox to select all songs, shown in alphabetical order.  Also, typing in a 
     * page number will automatically call the setSelected() method to the song with that number.
     * Selecting a song will also automatically set the text in the pageNumber text area to that
     * page number.  There is another JComboBox that will choose colors. Also, there is another 
     * JTextArea that has verse numbers.  That will only display that verse, unless "Display all"
     * is checked in JCheckBox check.  There will be no exit button, but the JMenuItem exit under the 
     * JMenu options under JMenuBar menuBar will allow the user to exit.  Also, there will be a JComboBox
     * for font types and font colors.  There will be two more JMenuItem under JMenu options that will 
     * set the background color and the foreground color of the JPanel, to the color specified in each of the 
     * sub-items of those two JMenuItems.

    Just look at the save ActionListener part.

    I only added the imports and stuff because you keep asking for them.

    Also, when I tell it to exit and then tell it no, it opens a blank JFrame. I'm wondering if it's saving but somehow saving nothing. Also, why is it doing that when I exit?

    Your program is too large to work with.
    Can you make a small program that compiles and executes to demonstrate the problem?

    Ok, here's a question.

    Where do you tell it what data to save to the file?

    I dont know anything about saving using JFileChooser, but I can google. See if the saveFile() method helps you with actually telling the file what to contain: Java JFileChooser Examples

    Where do you tell it what data to save to the file?
    Hard question to answer.
    The quick answer is somewhere in your code.
    The "what data" is really hard. What do you want to be able to retrieve later?

    I dont know anything about saving using JFileChooser,
    JFileChooser is a way to have the user select where to write a file. That's what it does, let the user tell the program where or if.
    You can logically replace using that by just hard coding a path in your program.
    Given a path to where the file should go (choosen or hardcoded) then you write the file at that path.

    I want the everything to be there. For instance, make a JTable, add text to it, hit save, and then load it and have the text still in it. Plus I wouldn't mind having the background and the JPanel come up too. I basically, though I quite realize to do so might well be anything but basic, want to have it show what I had made originally in the program come up, but with certain text fields, textAreas, and JTables, that's for another one that I'm practicing here first before I make it, to be there.

    Basically to almost get an auto setText() for certain things. Like saving the text and settings in a Microsoft Word document is about the best I can can describe what I'm trying to do.


    Also, what does FileOutputStream class do?

    I usually hardcode my output paths and use JFileChoosers for my input paths. It actually never occured to me that I could let the user select where it goes. However, usually the only file manipulation I do involves either directly editing the input file or creating an output file identical to my input file with a few changes and preserve the input file. So my files usually go in the same directory as the input file and I just never thought about it.

    A file output stream is an output stream for writing data to a File or to a FileDescriptor. Whether or not a file is available or may be created depends upon the underlying platform. Some platforms, in particular, allow a file to be opened for writing by only one FileOutputStream (or other file-writing object) at a time. In such situations the constructors in this class will fail if the file involved is already open.

    FileOutputStream is meant for writing streams of raw bytes such as image data. For writing streams of characters, consider using FileWriter.

    Got that from the API. It actually makes sense, which is more than can be said for most of the class descriptions.


    I would think that you need to figure out how to write to either .doc,docx, or .rtf and use those formats to write your files. Or, some would criticize this, but if you wanted the largest range of formatting options, .xlsx would probably be the best.

    Default Re: Can't get it to save stuff with JFileChooser

    If you are working to save certain data into a file, you must first settle on a specific file type so that you know where and what things are when you reopen the file. Just saving it to a file is one thing, but having the means to make sense of it is a whole other issue - especially when you are talking about saving data from multiple components. One option you may have is to Serialize the classes into a given file....this will allow you to use an ObjectOutputStream and ObjectInputStream and rely on the java virtual machine to do the file writing and reading, all you need to do is tell the stream which object(s) to read write (the drawback to this method can come into play later when making changes to objects - previously saved files may not be forward compatible).

    As to why your code results in emtpy files, I concur with Norm that it is much easier to lead you in the right direction if you can boil that code down to as few lines as possible to reproduce the problem you are having.

    Is there a way I can add the Components to the saved version? How do you Serialize something?

    Suppose I have a JPanel, which has a title as class extends JFrame, a JTextArea, and a couple of buttons.

    How do you tell the saver
    save
    {
     
    Panel
     
    Panel.setVisible(true);
     
    JTextArea
     
    JTextArea setVisible(true);
     
    JTextArea(setText(userInputtedText));
     
    add(button);
    add(button2);
    add(button3);
     
    button.setVisible(true);
    button2.setVisible(true);
    button3.setVisible(true);
     
    add(button's ActionListener());
     
    add(button2's ActionListener());
     
    add(button3's ActionListener());
     
    }

    Default Re: Can't get it to save stuff with JFileChooser

    I'd suggest that you write a small test program with a few simple classes and work on writing them to a disk file using a ObjectOutputStream and then read them back with a ObjectInputStream and verify that you get back all of what was written out.
    No GUI needed. Use println() to show success or failure.
    When the technique is mastered, then move it into the larger program.

    JFileChooser only lets you select one or more files/directories. The actual saving out of the data is a separate issue and should behave exactly the same as when using a hard-coded path.

    In order to serialize an object, you just need to have the object implement the Serializable interface (easy), and also make sure every component inside of that object is Serializable (hard because you have to include all fields that get inherited).

    To write out an object, simple create an ObjectOutputStream to the file in question, then call writeObject() on the object you want to write out.

    For an example of this, see Writing Objects to a File with ObjectOutputStream. Reading objects back in has a similar idea. See: Reading objects from file using ObjectInputStream.

    What do you mean that I have to include all of the fields that get inherited? Also, can it only be saved once and not saved over? What's not forward compatible? By fields, do you mean if I have a text area and it gets text I have to serialize the text too, or do you mean all the fields, like INFORMATION_MESSAGE, or HORIZONTAL_SCROLLBAR_ALWAYS, etc?

    Also, does any class have a method to check to see if a Class/component is serializable?

    a method to check to see if a Class/component is serializable?
    Try instanceof to test a class.

    if(theObject instanceof Serializable)
    {
        // the object implements Serializable
    }

    And if it isn't an instance of Serializable, does that mean I can't use it? If I can use it, what did you mean by "fields"?

    Hey, I got something to work!

    However, it's not quite what I was hoping for. Maybe if it were .exe or .jar it would work. Also, are a JTextArea and its text Serializable?

    Yes, you can only serialize objects that are.

    I thought I could actually, but I could only if I serialized all of the fields and all the fields it inherited.

    So how do you write Objects that aren't serializable?

    ---------------Editing-------------------------

    Hey, I just thought of something. Couldn't I just, if a class doesn't implement Serializable, could I make a subclass of it that does and thus be able to write it?

    For instance, say JTextArea won't serialize. Could I make a subclass called myJTextArea that extends JTextArea and that implements Serializable?

    Best way to answer all these "what if" questions is to write a small test program and see what happens.

    Lightbulb Re: Can't get it to save stuff with JFileChooser

    I have no clue what sort of file a regular GUI would be compatible with. I tried .rtf and it gave me just a Word doc with code, though it wasn't the same code, exactly anyway, that I had used to make the components. i tried jar and it didn't like it. I tried .exe and it didn't like it. Do I have to write something to make it loadable from anywhere or just from the program itself?

    How do you get it to "de-serialize" stuff?]

    Default Re: Can't get it to save stuff with JFileChooser

    If you serialize an object to a file using an output class, you use the corresponding input class to read the object back into a java program and recreate the object as it existed when it was written out. There is nothing you can do with the file that contains the object except read it back into a java program.

    Ok, but how do you get it to read the objects back in?

    I gave a sample program.

    How did you write them out? Take the class name and replace Output with Input

    I know I use ObjectInputStream and FileInputStream

    but what method?

    I tried using an ObjectInputStream.readObject() but it doesn't appear to do what I want.

    Perhaps I need to get it to remove all my current components first before reading in the updated ones.

    Also, when it's reading in, do I need to originally save it in a .java in order to be able to read it back in correctly?

    How do you get default de-serializing?

    Also, if default de-serializing happens to be abstract, what kind of super calls do I need?

    Also, do I have to tell it to close the reading in when it runs out of objects?

    Please explain "what I want".

    do I need to originally save it in a .java
    No you can use any file extension that you want. Chose one that won't confuse the OS. Like .dat or .ser

    Best way to answer all your questions is to write a small simple program with a small simple class with some data and a get method. Create an object from the small simple class with some data, serialize it to a file, read the object back in and call the method to get the saved data to see it matches what was saved originally.
