Displaying html page in JEditorPane

yeh, yeh, i know the editorPane.setPage(url) function. the problem is that the file i need to display (help.html) is on local drive, in the same dir as the class with the editorPane. so what url do i make [i don't know in which dir the class will be]. i tried to make it relative: URL url = new URL("help.html"), but it didn't work. this:
s = "file:\\"
+ System.getProperty("user.dir")
+ System.getProperty("file.separator")
+ "Help.html";
URL helpURL = new URL(s);
doesn't work either.
i work on win 95, jdk 1.3.
HELP ME!

Problem in displaying html page in JEditorPane....

Hi All,
i was trying to display a html page in a JEditorPane. i was able to do that when i'm displaying a html page from a local machine.. But when i try to get the page from some website, it giving me
"exception access denied (java.net.SocketPermission www.java.sun.com resolve)"
exception. But if i run the same code thru JBuilder, its working. But thru appletviewer or thru IE or Netscape its throwing the error.. Any suggestion or help is highly appreciated....
Thanks

Java Applets are very secure, what is good. Java applets are extremely secure
what is bad. So Applet cannot open TCP connection to any host rather than its
home host. So you cannot get the resources from any other server (what is common to
HTTP).
In JBuilder iit works cause JBuilder is used for development and security in deevelopment
is not an issue. But it confuses then you see.

Working with JEditorPane to display HTML page

iam loading html page into JEditorPane .
how to get the html form data to validate
give me soluation for this problem ...
thanks ....

Search for occurences of <img> tags in the stream and replace its src="" contents by for example src="image?id=orginatingimagefilenameorso" and write kind of an ImageServlet mapped on "/image*" which streams the right images to the response.
You may find this ImageServlet example useful: http://balusc.blogspot.com/2007/04/imageservlet.html
After all, why are you streaming HTML files through a servlet instead of just linking to them? Aren't they public accessible or so? If this is the case, consider creating a virtual host on the application server so that you can just access those files through a simple plain vanilla URL.

How to go to anchor html link from external html page in JEditorPane

Hi people,
I've been trying to jump to an anchor link from an external html page in JEditorPane, and I cannot get it working, I'm sure it can be done somehow...
The HTML page has a link like:
Hello
and this is loaded into JEditorPane ok.
The HyperlinkListener implementation:
public void hyperlinkUpdate( HyperlinkEvent e )
try {
if ( e.getEventType() == HyperlinkEvent.EventType.ACTIVATED )
editorPane_.setPage( getClass().getResource(
MyDialog.this.getBaseURL().concat( e.getURL().getFile().substring(
e.getURL().getFile().lastIndexOf( "/" ) + 1 ) ) ) );
if ( e.getURL().getRef() != null )
editorPane_.scrollToReference( e.getURL().getRef() );
else return;
} catch ( IOException ioe ) { ioe.printStackTrace(); }
This code loads the new html file ok, but it does not scroll to the anchor. The MyDialog.this.getBaseURL() just returns something like com.name.package, I construct the URL by using this base url and the name of the html file to open.
ANy help, thanks

he! I'm not alone in my desperation. Take a look at my problem:
I've got a JEditorPane (not editable) inside a JFrame. The JEditorPane is loaded with the HTML text and all the links to anchors are working properly when I click on them.
BUT
If I try to go to an anchor from outside this JFrame I can see how the JEditorPane scrolls to the right anchor and suddenly it scrolls back to the place where the caret was located!!!
The "funny thing" is that my code is working in jdk1.3.1 but this is happening in jdk1.4.2. Is it a bug?!?!?!
How could I figure out what position I have to set the caret to for every anchor in order to get the scroll working correctly???
My implementation of hyperlinkUpdate (working properly, here isn't the problem):
   jEditorPane.addHyperlinkListener(new HyperlinkListener() {
      public void hyperlinkUpdate(HyperlinkEvent e) {
        if (e.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
          MiEditorPane src = (MiEditorPane)e.getSource();
          src.goToAnchor(e.getDescription().substring(1));
    });My object jEditorPane is an instance of this class:
class MiEditorPane extends JEditorPane {
    MiEditorPane() {
      super();
    public void goToAnchor(String anchor) {
      super.scrollToReference(anchor);
}And this is the method I call from outside the JFrame containing the JEditorPane:
public void goToAnchor(String anchor) {
     jEditorPane.goToAnchor(anchor);
}Any help greatly appreciated ...

You have deleted your page, but you have not deleted your page?
Which is it?
If you never saved it it is gone. If you saved it in Lion (OSX 10.7) with Pages 09 v4.1, there should be versions available when you mouse overv the document name at the top of the window.

Displaying HTML page from JFrame

Any Way to display HTML pages on Applet

Hi All,
Is there any way to show web pages on Applet?
Is it possible ?

I am not aware of a simple way to display HTML in an applet. However, I have used the JEditorPane to display HTML documents. Handling links, etc. with this component requires some effort. Also requires Swing.
Have you considered using the applet to display a page on the browser. (i.e. getAppletContext().showDocument(URL, [frame name]))? Just an idea.
Good luck.

Displaying HTML Page

I am having problems getting my HTML file to actually display. I think I can retrieve the file properly - I'm not getting any errors saying I can't. But when I do retrieve it, I just get a white scrollpane, instead of a scrollpane containing the webpage it should be. The following code is for an object constructor that creates the window that shows the webpage. Any help would be greatly appreciated. Thanks.
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
import java.net.URL;
import java.io.IOException;
public class OnlineHelpWindow extends JFrame
     public OnlineHelpWindow()
          super("Online Help");
          Container c = getContentPane();
          JEditorPane editorPane = new JEditorPane();
          editorPane.setEditable(false);
          String s = null;
          try
               String prefix = "file:" + System.getProperty("user.dir") + System.getProperty("file.separator");
               URL url = new URL( prefix + "index.html" );
               System.out.println(url);
          catch (Exception e )
               JOptionPane.showMessageDialog(null, "Unable to load URL: " + s,
                                                            "Unable to load URL",JOptionPane.WARNING_MESSAGE);
          JScrollPane editorScrollPane = new JScrollPane(editorPane);
          editorScrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
          editorScrollPane.setPreferredSize(new Dimension(250, 145));
          editorScrollPane.setMinimumSize(new Dimension(10, 10));
          c.add(editorScrollPane);
          pack();
          show();
}

I think you forgot to put the html page in the editor
try putting the url in the constructor, so the url must be define first.
JEditorPane editorPane = new JEditorPane(url);
It should work
