HTML in JEditorPane question

Hello
I am having trouble with displaying HTML with image maps in JEditorPane component. I am trying to load a simple html file as follows:
<html>
<IMG SRC="monk.gif" HEIGHT="255" WIDTH="262" ISMAP USEMAP="#mapareas">
<map NAME="mapareas">
<area SHAPE=CIRCLE COORDS="107,158 132,162" HREF="basic.htm" ALT="Basic Page">
<area SHAPE=default HREF="index.html">
</MAP>
</html>
There is no problem with displaying the image. It's rendered fine without any problem. But, When I click on the circle area, I can't seem to get the URL corresponding to the map area. I tried the HyperlinkEvent::getDescription() and HyperlinkEvent::getURL() methods and both of them return the reference to the map as opposed to the reference specified for the specific map area ( in my case, "sample.map" instead of "basic.htm" ).
Can someone tell me if HTML with image maps is supported in EditorPane? if so, how do I get the reference to the map area clicked?
thanks in adv

JTextComponent.viewToModel
then get the element at that location, either the character or
paragraph element, then get its StyleContext.NameAttribute value, which is a HTML.Tag.
That was a fun walk round the API, to find out more, I recomend reading through JTextComponent, and its Model/View Split section.

Problem to display Animated Gif from HTML into JEditorPane

I have a problem displaying animated gif that comes from URL (HTML) into JEditorPane.
Let me show you the source I have:
* @author Dobromir Gospodinov
* @version 1.0
* Date: Dec 6, 2002
* Time: 6:47:53 PM
package test.advertserver;
import javax.swing.*;
import java.awt.*;
import java.io.IOException;
public class Test {
 public static void main(String[] args) {
 JFrame frame = new JFrame();
 JEditorPane ed = new JEditorPane();
 try {
 ed.setPage("http://localhost:8200/servlet?key=value");
 } catch (IOException e) {
 e.printStackTrace();
 JPanel panel = new JPanel();
 panel.setPreferredSize(new Dimension(500, 500));
 panel.add(ed);
 frame.getContentPane().add(panel);
 frame.pack();
 frame.setVisible(true);
}Part of the returned from servlet HTML includes an img tag:
<img src="/images/MyAnimatedGif.gif" alt="animated gif comment" width="480" height="50" border="0">Let us assume that MyAnimatedGif.gif has 10 frames and gif is looped - when the 10th is dipslayed it has to display the 1st and so on.
JEditorPane displays frames from 1 to 10 correctly but does not start from the first again. Instead JEditorPane displays a broken image.
I locate where the problem arise:
JEditorPane has an HTMLEditorKit that creates javax.swing.text.html.ImageView instance for every IMG tag.
And here is the problem:
ImageView has an ImageObserver necessary for the asynchronous image download. ImageObserver has the imageUpdate method. But this imageUpdate method is never called with ALLBITS flag raised up. Instead, after the last frame of MyAnimatedGif.gif is downloaded the imageUpdate method is called with flag ERROR raised up. Obviously this is a bug of Sun's implementation. Finaly the flag ALLBITS has to be received for normal end of image observing. But ALLBITS flag does not come.
So, can anybody help me how to load an animated gif within JEditorPane completely.
Thank You in advance,
Dobromir Gospodinov
P.S. If somebody of you wants to debbug what happens within ImageView will have to implement it (and related classes too, because of the limited package visability) borrowing the source from Sun's ImageView.

I'm also having this problem with java 1.4.1 I discovered that some animated gifs work fine, while others stop animating. Running with java 1.3.1 fixed the problem. I'm going to report this as a bug
Here's my code:

Display HTML in JEditorPane

Hi
I am trying to display a String containing HTML text on a JEditorPane.
I have downloaded the HTML from a webpage using sockets, and now I want to display the downloaded page. I have a project in school about sockets.
This is why I can't use getPage(URL);
The following is the code I am using:
String temp = "String with HTML text"
HTMLEditorKit htmlEdKit = new HTMLEditorKit();
JEditorPane.setEditorKit(htmlEdKit);
JEditorPane.setContentType("text/html");
JEditorPane.setEditorKitForContentType("text/html", htmlEdKit);
JEditorPane.setContentType("text");
JEditorPane.setText(temp);
When I run the code, all that is displaying is the raw HTML code, with all the tags. As I understand it, this is how it should be done.
What is wrong, would appreciate some help.
/David Mossberg

it's not necessary to use socket but if use socket get the inputstream from it.
in = socket.getinputstream(); //return inputstream from socket
htmldoc = JEditorPane.getDocument(); //return the htmldoc in JEditorPane
if(htmldoc.getlength()>0)
htmldoc.remove(0,htmlDoc.getLength());//if the htmldoc has some content then remove it
reader = new InputStreamReader(in);//construct a new reader from in
JEditorPane.getEditorKit.read(reader,htmldoc,0); //read new content into the htmldoc from reader
Hope the above code helps you.

Java word HTML microsoft com question

Hi:
I am very new to Java and I don't need to you write any code for me, so please don't flame me :D
I am in the process of planning a utility that will convert/assemble Microsoft Word Docs into HTMLs and then build search/sort/etc functionalities on the HTMLs.
My question: I guess this can be done in Java via COM bridge in Windows. Is it the same on Macintosh/Apple platform? Do Apple even have a COM interface as well that a Java program can utilize? If not and I am limited to the Windows platform, I might not even need use Java at all.
Any other suggestions toward this idea is greatly appreciated. I got it to work with Perl and some freeware utlity that convets Word->Txt, and I then generate HTML from Txt with my links and stuff. I just want to make it more user friendly by providing some kind of interface/configurations.
Thanks!
Ray

I have not used it, but you might look into POI to parse the word docs, then you can output whatever you want - you might look into ECS to generate the HTML.

Good luck

Html in JEditorPane

Hello again! I am in the following situation. I have succeeded in loading an HTML document in a JEditorPane component. My question is can I recognize somehow if a click is performed on an image of the html document or on the text of the html document? If there is a possibility I would very much appreciate if you'd share it.
Thank you.

JEditorPane question

Hello Gurus,
Can some one help me with this.
I read a page using URL
after all the stuff I get the page( which is an HTML text) and display it in JEditorPane,it shows the html part ok but it just prints out the javascript on the page as text and it does not do anything when I click on a link on this page,I am new to this swing stuff,so please bare with me if my questions do not reflect me as an intellectual :-)

JEditorPane and HTMLDocument don't have code built in for parsing and formatting javascript. If you're going to try to correct this, take a look at the HTMLDocument.HTMLParser class

Hi kashif10,
JEditorPane or JTextPane are the classes to use. You can have both bold and italic for a text portion.
See http://java.sun.com/products/jfc/tsc/articles/ for an overview of articles covering the swing text package.
Or try application SimplyHTML at http://www.lightdev.com/template.php4?id=3 it is open source and has a lot of documentation too.

HTML DB Licensing question

Hi guys,
Given the following scenario:
Machine1- Oracle Standard Edition1
Machine2 - Oracle Http Server
Do I have to license Machine2 in any way or by licensing Machine1 does that cover the license for the Oracle Http server running on Machine2.
Reason: I want my database running inside my firewall on Machine1 with Machine2 sitting out in the DMZ.
Thanks

Sergio and company,
I'd like to suggest that someone official definitively answer this question.
Oracle is reaching out to the low budget and low experience users in a big way. It's an enormous market opportunity in my opinion. But how can we, your advocates for HTML DB, sell these systems to our executives without a solid understanding of the costs? To do so could risk personal jeopardy.
Could you publish a list of several configurations options with the capabilities of each and the cost?

HTML DB License question

Hello everyone,
I have a question regarding licensing of HTML DB, is HTML DB covered under the Oracle 9i and/or 10g database license or licensed separately?
Thank you.
Haider.

Actually, Oracle HTML DB is included as a part of the
following database licenses:
- Oracle 9iR2
- Oracle 10g SE One
- Oracle 10g SE
- Oracle 10g EE
Thus, if you have a current license for Oracle 9iR2
or 10g, you're licensed for Oracle HTML DB.
Don't forget Oracle XE, which has HTMLDB 2.1 embedded as the database management tool and application builder to boot!

Inserting HTML into JEditorPane

I have a window with a JEditorPane on top and a JTextField below it. I need to be able to type raw HTML into the edit field and have it appended to the HTML document displayed above.
For example if I type...
This is bold
I need to append that to the document. However I want the style to stick. Notice I did not close the tag above. I want the next line I enter into the edit field...
and so is this but not this.
I want this to appear bold up until the closing tag and then return to normal. The problem is that every time I append new text to the document the style is restored to normal.
I insert the text with the following code. I send the contents of the JTextField to the following function when I hit return.
void processInput(String input) {
try {
HTMLDocument doc = (HTMLDocument) output.getDocument(); // output is my JEditorPane
editor.insertHTML(doc, doc.getLength(), input, 0, 0, HTML.Tag.BODY); // editor is HTMLEditorKit
// relevant catch clauses
Basically I want the two broken input sequences to appear in the editor as one seamless entry. I want to be able to type these two entries and have them show up as if they were entered as one entry.
entry 1:This is bold
entry 2: and so is this but not this.
I want to somehow cause this to be displayed as if I typed...
This is bold and so is this but not this.
Is there a way I can do this?
Thanks.
-Russ

as i understand you you want to write
entry 1:This is bold
entry 2: and so is this but not this.
in two lines
Try this
entry 1:This is bold 
entry 2: and so is this but not this.

Applet use with HTML// also appletviewer question

I am new to the language. I am trying to start an applet in a folder that I created on my hard drive(C:). I have included the following code in my HTML in my folder.
<applet code="NotHelloWorldApplet.class"
width= "300" height= "300">
</applet>
I have already compiled the program; I have the net beans 1_4_2 compiler, and it has compiled without errors.
The code is :
import java.awt.*;
import javax.swing.*;
public class NotHelloWorldApplet extends JApplet
public void init()
Container contentPane = getContentPane();
JLabel label = new JLabel("Not a Hello, World applet",
SwingConstants.CENTER);
contentPane.add(label);
I have also downloaded Plug-In; if that means anything. When I open the HTML folder a grey box appears; then at the bottom of the window it says that it cannot find the file; even though the file exists(I have looked with the file finder and it is in my file directory). Is it in the wrong directory? How does the file folder in windows know how to run and execute a java program with the preceding HTML code. This is the method explained in a current text book that I am using. It tells me to
1. to compile the source code into class files.
I used the compiler and I successfully created a .class file, (obviously the title of the program is .java program, but the class file does exist.
Then 2. add the above code in the HTML program(which I did).
I would like to get applets running but do not know how to correct this problem. Is there more HTML code that I need to run a java program in the folder's code.
Also, the textbook I am using tells me to preview the applet with appletviewer. I loaded the appletviewer into the editing screen and it is a bunch of hieroglyphics. One of two possible problems are that it is not included with the Net_Beans_1.4.2(it was from another download) or the download was contaminated. Anyway, the question I have is; is appletviewer an application that is viable with Net_Beans_1.4.2 and if it is from where and how do I run or execute it to preview my applets before I run them inside an HTML document.

Sounds to me like you're having trouble with NetBeans, not applets or appletviewer. You should consult their docs on how to access their version of appletviewer.
It also sounds to me like you're using the book CoreJava by Horstmann/Cornell.
Notice that they package TextPad with their book. This is for a good reason. It is very easy to be suckered into thinking you know what is going on when you have an IDE that does stuff for you. I know. I programmed in VB for a while, and I thought I knew how to do Windows programming. But I didn't. VB was doing all the work for me while I was drawing boxes on the screen and patting myself on the back. It took several major blows to the ego before I found out that all I really knew how to do was how to draw a bunch of silly boxes.
New programmers should start out with a text editor. They get a better feel of what is going on.
I don't know how NetBeans works -- even now I prefer TextPad over any IDE I've tried. But appletviewer works in the same way the java and javac command works, except that the argument it takes is the name of the html file which contains those applet tags (<APPLET>).
I have some thoughts on your problem:
1) you have an html file somewhere, but you don't know where. It is somehow created in a "window". the tag
applet code="NotHelloWorldApplet.class"
means "look in this directory for the class NotHelloWorldApplet.class" So if the html file you have created is not in this directory, how will appletviewer (or NetBean equivalent) know where it is? (hence, "class not found")
2) Is this correct? You have downloaded the plug-in for your browsers, but you didn't try using your browsers to see the applet?
If so, try this: go to IE or Netscape (or whatever you favorite browser is) and try in IE File-->Open and hit the browse button, or in Netscape File--> Open File
Next, try to find the file "NotHelloWorldApplet.html" or whatever it is you called the "window". Open the html file.
If it doesn't work, check to see if the html file is in the same directory as the class file (repeat procedure, but now look at files of type "All")
3) You can make an html file with notepad. You don't need anything special. Just type in the html code that Horstmann/Cornell include into notepad and save as an html.
Does this help?

Inserting HTML in JEditorPane

Extremely frustrating trying to work with the HTML editing model (JEditorPane - content type text/html). I am using 1.4.2_06. Tying some basic actions to buttons or keystrokes is no problem (eg bold, italic etc.) but the most NB things like being able to drop a in where the user presses enter doesn't seem possible. Has anyone found a way to drop in HTML at the caret? Would hugely appreciate any ideas.
Matthew

Ok, figured it out myself:
notesArea.getInputMap().put(KeyStroke.getKeyStroke("enter"), "enterAction");
notesArea.getActionMap().put("enterAction", new HTMLEditorKit.InsertHTMLTextAction("InsertBR", " ", null, HTML.Tag.IMPLIED, null, null));

Rendering html in JEditorPane

hi
i have a problem in JEditorPane.
when i rendering a html with frameset then i cannt resize the frames (like JSplitPane) but it working in browser.
so how i do it in JEditorpane??
thanks

I think it just ignores it, but I could be wrong. If you want to do what you are saying, I think you need some custom document or something. The standard classes aren't going to help much, as far as I can tell.
