    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE HERE
    [/code]
    to get highlighting and preserve formatting.

    Does it say anything in the API doc for the classes you are using about displaying SWF files?

    file is not loading properly
    Please explain what it means to "load properly".

    Why do you think the code you have posted is capable of displaying swf files?

    it will not display
    What is supposed to be displayed?

    Have you tried the code with a simple html file to see if it is displayed?

    not able to display html file
    First work on getting something simple like an html file to display.
    Make sure you get the full text of any error messages by calling the printStackTrace() method in the catch blocks.

    Default Re: How to display .swf files in java code JEditorPane using eclips platform

    There are 3 immediate problems that you need to fix first.

    1. Multiple JEditorPane instantiations

    In your code you have:
    Quote Originally Posted by chetu7845 View Post

    window_pane=new JEditorPane();
    window_pane.setBounds(10, 50, 600, 600);
    pane.add(window_pane);
    ...
    window_pane = new JEditorPane("http://www.yahoo.com")
    {
        public boolean getScrollableTracksViewportWidth() 
        {
            return true;
        }
    };
    ...
    The 2nd JEditorPane instantiation is unnecessary, in fact it causes problems for #2 below. Remove it.

    2. Lack of stack trace display
    Quote Originally Posted by chetu7845 View Post
    ...
    public void actionPerformed(ActionEvent ae)
    {
        JFileChooser fc = new JFileChooser();
        int result = fc.showOpenDialog(null);
        if (result == JFileChooser.APPROVE_OPTION)
        {
            File file = fc.getSelectedFile();
            ...				
            try 
            {
                if(ext.equals("swf"))
                {
                    window_pane.setPage(address_tf.getText());
                    System.out.println("hi");
                }
            } 
            catch (MalformedURLException e) 
            {     // new URL() failed
                window_pane.setText("MalformedURLException: " + e);
            }
            catch (IOException e)
            {               // openConnection() failed
                window_pane.setText("IOException: " + e);
            }
        }
    }
    ...
    Make it a habit during development to always print out the stack trace to standard error via e.printStackTrace(), or log the exception stack trace into a file. Because of #1 above, the exception that is thrown in the code above is not set into window_pane. Consequently, the code fails silently.

    3. JEditorPane.setPage() requires a URL

    The exception mentioned in #2 is a MalformedURLException. This is thrown by
    window_pane.setPage(address_tf.getText());
    Make the Java API docs your friend. In this case the relevant doc page is JEditorPane (Java Platform SE 7 ). You'd see that there are 2 versions of the setPage() method:
    • setPage(String url)
    • setPage(URL page)

    Either way you need to provide it a URL, in String form or a URL object, and not a file path. Since you already have obtained a File object earlier via File file = fc.getSelectedFile(), you can simply set the page using
    window_pane.setPage(file.toURI().toURL());

    After you have fixed the above, as Norm suggested, try to display a simple HTML file first. This implies you need to either modify or temporarily remove
    if (ext.equals("swf"))

    Btw note that you can set up JFileChooser to filter and display just the types of files that are of interest. See How to Use File Choosers (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components).

    You should first become familiar with the capabilities of the Components you are using (usually by reading the API docs). Presuming 'swf'/'fla' are referring to a Adobe flash media - at this time JEditorPane does not have this capability, which from glancing at all the posts above seems to be what you are trying to do.

    Please elaborate on how you'd like it to work. E.g., do you want to display the swf file as if it was in a browser? I see on the GUI there are sections for DOM Structure and Attribute. How will they be used?

    copeg is right that JEditorPane does not support swf. JEditorPane (Java Platform SE 7 ) lists the supported content types. Therefore the solution (if exists) depends on the answers to the questions above.

    What packages and classes do you have for displaying swf files? There are none in standard java to do that.
    properties of the swf image file
    What packages and classes do you have that will get that information from a swf file?

    Please reconfirm that it is SWF files that you need to deal with, and not SVG files. Also, please elaborate on the aim of this college project - what your prof expects you to learn from this project. I'm asking because I'm struggling to see what you might want to put into the DOM structure pane, but if it is SVG that you need to deal with, then it makes complete sense.

    If you're 100% sure that you need to work with SWF, then Transform SWF For Java might be of help. It is a library that can read/write SWF files. Since you mentioned "image", I'm assuming you'll need to extract image(s) from the file, in which case do an Internet search using the search term "extract frame|image site:flagstonesoftware.com". E.g., one of the results from my search is Flagstone Software - View topic - Extract a frame to Java BufferedImage. You can also widen your search using the search term "java flagstone transform swf extract".

    Those requirements are NOT part of standard java. You will need to use packages from other sources to do it.
    Several links have been provided to other sites that might be useful for you.
