JEditorPane - setPage

How does one interrupt the loading of a HTML page in setPage of a JEditorPane? Have a situtation where clicking on different URL's should
stop the loading of the previous page...
Thanks

If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)", that demonstrates the incorrect behaviour.

Don't forget to use the "Code Formatting Tags", so the posted code retains its original formatting.

hi all
if anyone can help me...please help

But how can I cause GUI thread to run in my thread
group? As I suppose GUI thread is started by JVM and
is something separate from my code - I can get a
reference to GUI thread but don't know how to
manipulate or replace it...One alternative is to completely separate the GUI code from your code.
Your code, which is wrapped in appropriate try/catch blocks, runs on its own thread and does its own processing. When it's done with that processing, it queues the results on the event thread for display. If an exception occurs during your processing, then you queue something that notifies the GUI.
The simplest way to implement this is to spawn a new thread for each operation. The Runnable that you give to that thread looks like the following:
public MyOperationClass implements Runnable
    public void run()
        try
            // do your exception-generating code here
            SwingUtilities.invokeLater( new MyGUIUpdateClass(param1, param2));
        catch (Exception e)
            SwingUtilities.invokeLater(new MyExceptionReporter(e));
}This is only a bare-bones solution (and hasn't been compiled). Since it separates the GUI from actual processing, you'll probably want to display a wait cursor while the processing thread is doing its thing. You'll probably end up implementing a class that implements this pattern. You may also want to create a producer-consumer thread, so that the user won't invoke, say, a dozen different operations at once.
However, this sort of code is absolutely essential to Swing programming. Most apps do extensive non-GUI processing, such as database queries. If you run such queries in the GUI thread, your GUI will freeze.
Sun has named this pattern "SwingWorker", although I don't think they've fleshed it out very fully: http://java.sun.com/products/jfc/tsc/articles/threads/threads2.html

JEditorPane, setPage and EDT

The setPage(URL url) method for JEditorPane creates a thread and then loads the URL specified. In our software we're using something to check if all work dealing with Swing components is being done on the EDT. The code for this can be found here:
http://www.clientjava.com/blog/2004/08/20/1093059428000.html
Anyway, it turns out that the setPage method is not doing its work on the EDT, which seems like a bug since modifying a component off the EDT can lead to problems. Anyone want to shed some light on this topic or tell me if there's anything that can be done about it? Thanks.

I am using setPage(URL) method to display files selected from a fileTree.
I am facing a file locking problem, because of the the PageLoader thread spawned by the setPage method.
The file is locked temporarily some times and prevents other applications to edit it.
Can anyone help me what should I do to solve this problem?

JEditorPane.setPage - detecting that asynchronous image loading is complete

Hi,
I'm using a JEditorPane to load and display an html page of a url by using
setPage(String url) ... and I've added a progress bar to show the user that loading is still occuring.
Currently i'm detecting that the page has finished loaded by listening for the property change event named "page", like this:
    this.viewEditorPane.addPropertyChangeListener(
      new PropertyChangeListener() {
        public void propertyChange(PropertyChangeEvent event) {
          if (event.getPropertyName().equals("page")) {
            loadingProgressBar.setIndeterminate(false);
            System.out.println("... finished loading");
      });I appreciate that images are loaded asynchronously.
So what I'm wondering is how I can detect that all these associated images have also completed loading?
Thanks ... Dougall

if you want to load images synchronously you can use like, (i got it from this forum only)
public class SynchronousHTMLEditorKit extends HTMLEditorKit {
    public SynchronousHTMLEditorKit() {
    public ViewFactory getViewFactory() {
        return new SynchronousImageViewFactory(super.getViewFactory());
    static class SynchronousImageViewFactory implements ViewFactory {
        ViewFactory impl;
        SynchronousImageViewFactory(ViewFactory impl) {
            this.impl = impl;
        public View create(Element elem) {
            View v = impl.create(elem);
            if((v != null) && (v instanceof ImageView)) {
                ((ImageView)v).setLoadsSynchronously(true);
            return v;
}

JEditorPane.setPage halting other threads

I'm in the process of creating a program which loads a html-file while I'm running another process at the same time. It seems like setPage halts my process after a short while.
As an example I slightly altered a piece from a tutorial (http://www.apl.jhu.edu/~hall/java/Swing-Tutorial/Swing-Tutorial-JEditorPane.html)
to include a button which is counted down with the help of a timer. As you can see, it's halted for about a second or so after a short while.
Is there any way I can keep the countdown going fluently?

Thank you very much for the replies so far. :)
I am currently on a machine with duo-core, but I'd like to make my program compatible with the ones with single as well anyways. I guess I could find a way to have the processes run sequentially instead of parallely, but it would be really neat if I could get it working as I've intended. :)

Transfer all purchases from the iPad to iTunes on your computer, backup the iPad and then sync one last time.
Then go to Settings>General>Reset>Erase all content and Settings to completely erase the iPad.
Connect the new iPad to your computer and launch iTunes, restore from the backup of the old iPad and then sync with iTunes. You should be prompted to restore from the backup when you connect the new iPad to your computer's iTunes, but you can select it on your own as well.

JEditorPane setpage() problems

Hi all!!
I am developing a SWING application wich consists of a JFrame that contains a splitpane with a JTree on the left side and a JPanel with a cardlayout on the right one.
Once the user navigates through the tree on the left different cards get loaded on the right panel.
My problem is that when I show the card where a JEditorPane is located and use the setPage(url) to modify the document to be shown nothing happens, meaning that it doesn�t change the document that is displayed (the one URL that I passed on creating the JEditorPane). I mean, the card gets loaded, and I have confirmed that the URL that I pass exists and I pass different ones as well, but nothing seems to happen and the document remains the same.
Please, can you give me any hints of why this is happening? Can I repaint the card or something??
Is there any relationship between the CardLayout and the unability to setPage the JEditorPane.
Please Help!!
Here is the code:

I've had this Problem when I was building a HTML-Editor-Applet.
The Problem was, that there was a Style-Attribute like e.g. text-decoration:underlined. If I removed the underlined style the Attribut was text-decoration:none, but the getText() method just cared about the Style with the name text-decoration to handle this Element as underlined. I had to build my own getText() method by examing all the Elemntes from the Document and set the html-Tags for the style-attributes.

JEditorPane.setPage() final phase takes a while!!!

Hi Java users,
I'm displaying a document on a JEditorPane. I am using a SwingWorker to launch a thread that will accomplish the document load. However, there is a point when the SwingWorker has already finished his job (I now this since the finished() code has been executed), and it takes a few seconds more to display the document during which period I don't have any means to inform the user that all is in order and tell him to be patient. The JEditorPane shrinks to a tiny little white rectangle (almost a point) then -few sec. later- the document is shown. How can this issue be solved???
Also, hard question, in spite of using the SwingWorker sometimes (withou any systematical pattern, randomly) the GUI "freezes". How is this possible?
Thanks for your help in advance,
Balint

setPage already launches a separate thread to load
the page; hence the method may return before the job
is actually done: that terminates the SwingWorker
construct. You control that via set/get
getAsynchronousLoadPriority, which in turn use the
AbstractDocument.AsyncLoadPriority priority: only if it
not set (<0) the document will load synchronously.
The GUI may freeze because it has less priority than
needed. I use the following function   private static void lowerThreadPriority()
      Thread t = Thread.currentThread();
      int p = t.getPriority();
      if (p > Thread.MIN_PRIORITY)
         t.setPriority(p - 1);
   } to lower the priority of a SwingWorker, as they
start with the same priority of the GUI.
The GUI thread needs to gain read access to the document
to update the display as new data is being loaded. So,
it is important that the function that loads the doc
does not lock it for writing for the whole process, if
you want data to become visible before loading ends.

Loading JEditorPane from an XML file parsed by

an XSL translator.
the JEditorPane setPage needs a URL, I'm wondering if there is anyway way to have the XSL tool write directly to the JEditorPane?

If the XSL translator is producing HTML, and it can be run at the command line and send its output to stdout (as many of them can), then there's an approach to a solution.
JEditorPane has a read() method that takes an InputStream as a parameter. You could use Runtime.getRuntime().exec() to run the XSL translator, then use getInputStream() from the resulting Process object to capture its output, and give that InputStream to JEditorPane.read().
That's an outline of what I would try. Runtime.exec() is a notoriously irritating thing to get working, so it might fail, but you could give it a try.

Problem using Proxie server with Authentication & JEditorPane

Hello
I don't know if anyone has done this and if someone has I would really appreciate any help you could give me. I need to display a web page in a JEditorPane but the web page is accessed through a proxie server that uses authentication. I have tried using the setPage with username:[email protected] URL format for authentication but it doesn't work.

URGENT: JEditorPane (a Java Browser) displaying HTML form

Hi,
I am using JEditorPane to display the wb pages but geeting problem as
I don't get any kind of event when I click on the HTML form SUBMIT button though it does work but didn't allow me to get the URL of the new page that I got after hitting this SUBMIT button..
I searched the whole net and it seems to me that lot of people got this problem...
As I need this for my project please HELP me as soon as possible.

This may be too late for you (hopefully not), but I had the same problem a little while ago and just figured out how to fix it. Basically, you need to examine the Element structure of the html yourself and manually handle the form, as far as I can tell. There are several ways to display a URL in a JEditorPane, but the most straight-forward (JEditorPane.setPage(URL url)) doesn't actually store the Element structure anywhere accessible. Here's the code to load the page:
JEditorPane contents;
HTMLEditorKit kit = new HTMLEditorKit();
HTMLDocument htmlDoc = new HTMLDocument();
contents.setEditorKit(kit);
contents.setDocument(htmlDoc);
URL url = new URL("http://blahblahblah.com");
contents.read(url.openStream(), htmlDoc);Now that you have the page loaded correctly, you can access to the Elements within. You can use htmlDoc.getDefaultRootElement() to get the root and then iterate recursively through all the child Elements, checking out the Attributes of each. This will look for the submit button and add a listener to it for you:
private void parseElements(Element elem) {
    AttributeSet atts = elem.getAttributes();
    //If this is the submit button, add a listener:
         Object model = atts.getAttribute(StyleConstants.ModelAttribute);
         Object type = atts.getAttribute(HTML.Attribute.TYPE);
         if ((type != null) && (type.equals("submit"))) {
             DefaultButtonModel btn = (DefaultButtonModel) model;
             btn.addActionListener(new ActionListener() {
                 public void actionPerformed(ActionEvent event) {
                     System.out.println("Yay!");
    //Recurse
    for (int i = 0; i < elem.getElementCount(); i++)
         parseElements(elem.getElement(i));
}Of course, printing out "Yay!" is not really very helpful. When you're parsing through the Elements, check for the attribute StyleContsants.ModelAttribute. If that exists, you can cast it to the correct type of Model (see the documentation for HTMLDocument.HTMLReader.FormAction for information about what types of models to expect from what types of HTML elements) and store it until the "submit" button is pressed. Then all you have to do is get all the data from the models, format it and submit it to the action URL in either a "get" or a "post." The action URL is stored, in Java 1.3, in the HTML.Tag.Form attribute of one of the Elements (I don't remember which one). Getting that attribute returns a SimpleAttributeSet, and you get the HTML.Attribute.Action out of that. In Java 1.4 it's easier to find, you just have to look for the HTML.Attribure.Action attribute in one of the Elements.
Why isn't this all automatically done for you? I don't know. Good luck.

Displaying a webpage in a JEditorPane from a JApplet

Hi.

I seem to recall something about an applet only being allowed to access pages on the same server. Is there any way to display an external webpage in a JEditorPane? Thanks.

Unless you sign the applet's jar, you can only fetch urls from the same host as the applet was downloaded from. Part of the sandbox security restrictions.
So go look up jarsigner for details.

JEditorPane doesn't redraw if URL same

I'm generating HTML by styling an XML file using XSLT to a temp HTML file and using jEditorPane.setPage( tempURL ) to display it. No problem there. However if I regenerate new content to the same file name and ask JEditorPane to draw this then it says to itself "this is the same URL I put up before so I'm not going to redraw it" - even though the actual contents of the file have changed.
I don't want to have to use a different temp file for each run, or even to flop back and forth between 2 temp files (which I believe would work).
How do I get JEditorPane to redraw if the file name is the same as the previous call?

Here's my solution - I replace the HTMLEditorKit if it's not the first pass through. I found that the EditorKit is an instance of HTMLEditorKit for every pass except the first (which doesn't have a problem).
EditorKit ek = displayJEditorPane.getEditorKit();
if( ek instanceof HTMLEditorKit ) {
     // Needs to be replaced
     HTMLEditorKit htmlEditorKit = new HTMLEditorKit();
     displayJEditorPane.setEditorKit( htmlEditorKit );
// Display the HTML document
displayJEditorPane.setPage( resultURL );I'll spread my Duke Dollars around to everyone who offered a suggestion later today if I don't hear of a better solution.
Thanks.
