JEditorPane.... HTML file
Please Help...
I have been trying to add an HTML file to my JEditorPane
using the setPage(URL/String) methods, I have had no luck,
it throws some "unknown protocol: c" i understand that it
is expecting a protocol like http:, the likes, but how do
I bypass this as I want it do display an html file which
is on my local drive... I do not want to use setText(String)
setting my HTML tags in string...
Thanks in advance
Kaneval
Create a file object for you local html file. Convert
this file to a URL object.
File htmlFile=new File(fileName);
URL myhtmlUrl=htmlFile.toURL();
Then you can use this URL object to display the html
page.
Thanks a lot

HTML file is not being shown properly in the JEditorPane
Hi,
I am using JEditorPane to display an HTML file from the local disk. This HTML file contains the html tables. Now when this file is getting displayed in the JEditorPane, one top row grid is not being displayed in the editor pane. content of the row is there...but the column grid is missing. All other rows and columns are being shown but the first row-column grid which contains the heading for column.
Also when I m printing the content of this JEditorPane using Java Print API then no grid is being printed on the paper. content is coming properly but no table grids. when i have taken the print out of the original html file from the browser then table grids are being printed out properly.
Please do help me out in showing the HTML file in the JEditorPane properly and printing the same.
Many Thanks,
gshankarHi,
JEditorPane renders HTML with many limitations.
You can use JDIC for the same. refer: jdic.dev.java.net
But JDIC does not work on windows 98.

Print HTML file inside JEditorPane
Hi Guys,
I'm trying to print the contents of a JEditorPane - actually, a html file that I read and display in that component from the underlying file system. I've had the class that manages the JEditorPane implement Printable - the following is my print() implementation:
public int print(Graphics graphics, PageFormat pageFormat, int pageIndex)
throws PrinterException {
if (pageIndex > 0) {
return (NO_SUCH_PAGE);
} else {
Graphics2D g2d = (Graphics2D) graphics;
g2d.translate(
pageFormat.getImageableX(),
pageFormat.getImageableY());
ivTextArea.paint(g2d);
return (PAGE_EXISTS);
}I've got another method that gets called when a print button is clicked:
class .... {
PrintJob pj;
PageFormat pf;
private void printMe() {
if (pj == null) {
pj = PrinterJob.getPrinterJob();
pf = pj.defaultPage();
pf.setOrientation(PageFormat.PORTRAIT);
pf = pj.pageDialog(pf);
pj.setPrintable(this, pf);
try {
pj.print();
} catch (PrinterException e) {
throw new RuntimeException(e);
}Clearly I'm doing smth wrong, since only a single page gets printed and moreover the formatting is awful [text gets cut instead of moving on the next line]. Can someone help?
Thanks much!if (pageIndex > 0) {
return (NO_SUCH_PAGE);This is why you only get a single page.
page gets printed and moreover the formatting is
awful [text gets cut instead of moving on the next
line]. Can someone help?Yeah. Your best bet is either to put the editorpane in a scrollpane and just print what's visible, OR, you can take the print graphics object, convert it into a graphics2D object, and call scale on that by comparing component.getWidth/height to PageFormat.getImageableWidth/Height
I'm attaching my StandardPrint class. It uses the pageable interface to carry the number of pages + page format as well. I'm not sure if I did the scaling here or not, but I've done it before so I know it works :-) Also, I've got methods for previewing the print, which can save a lot of paper.
Please feel free to have and use this class, but please do not change the package or portray this as your own work

JEditorPane - How to display XML Linked HTML File in JEditorPane ?
Dear Friends,
I have a HTML File consisting of stylesheet, xml linked (for data) and with headers, footers...
When i called a ordinary html file using setpage property of JEditorpane..it's working no problem...but when i call the html file having xml linked or buttons...it's not properly displayed....
If anybody hits this problem....pls...help me....
Regards,
V.PrasannaIf you only need to display it, consider your HttpServletRequest just as byte stream. :) Just read from ServletInputStream and write it back into ServletOutputStream of HttpServletResponse.
If you want to process incoming XML, please give some details first, what exactly you want to do. :) -
JEditorPane problem with showing html file
Hey,
I have a JEditorPane in which I would like to show a HTML file that is stored in the same directory (local, not from the web).
String url = "index.html";
try
JEditorPane htmlPane = new JEditorPane(url);
htmlPane.setEditable(false);
frame.add(new JScrollPane(htmlPane));
catch(IOException ioe)
System.err.println("Error displaying " + url);
} It should also work once the whole program is "packaged" into a .jar file.
With the code above I cant get the index.html file to be displayed in the htmlPane.
Any suggestions?
thanks.The JEditorPane has a method called setPage that loads a URL into the pane, you can always transform internal jar locations to URLs using e.g. CurrentObject.class.getResource("/internal/jar/location/text.html")

Writing html file in a jeditorpane
I have read one of your threads titled as "How to insert a string in a JEditorPane (Urgent)". according to this thread I am using insertString() method to write in an jeditorpane. what I am writing is an html file. when I used insertString() method it doesn't show the html content in my jeditotpane. it displays the source code of my html file. I have setContentType("text/html"); moreover I used setText() and it shows the html file correctly but it over writes the previous content of jeditorpane. please help me to be able to
write to a jeditorpane without overwriting and displaying html file properly not its source code.
following is my code:
fr = new FileReader("myfile.html");
BufferedReader br = new BufferedReader(fr);
while ((lineread = br.readLine()) != null)
find.append(lineread);
do{
last = find.lastIndexOf("str");
Integer index = myJEditorPane.getSelectionEnd();
String temp = index.toString();
start=find.indexOf(temp, end);
end=find.indexOf("str", start);
Document doc = mynewContentPane.getDocument();
try{
doc.insertString(doc.getLength(),find.substring(start, end),null);
catch(BadLocationException exc){

If you mean a JEditorPane then please use the correct case, so we can be confident you refer to the J2SE class, as opposed to a 3rd party jeditorpane that we neither know, nor support.

How to put an HTML file into JEditorPane
Hi
I am doing an aplication on swing.But I don't know how to add a html file to the JeditorPane keeping the html file on the source code. i.e my html file is in my source code.Then how to add this source code to Jeditor pane.
Thanks
Srikanthi srikkant,
ur html code is inside the source code..? are you working on applets..? if ur html file can be read as a file and the file stream can converted to a string and put into a Jeditor pane using the setText() method. for editing HTML text a editor called javax.swing.text.html.HTMLEditorKit can be used.
Refer to JAVA API for further clarifiactions and examples. -

Is there to set one link's color in JEditorPane, when reading HTMl files?
I jsut want to set ONLY ONE link a certain color. How do I do that?
Thanks.
VirumIf you are just getting the JEditorPane to read in a HTML file then you would have to specify the HTML on the link you want, i.e. set the attributes on the "a" tag or use a style sheet.
Or course you could dive into the HTMLDocument used by the HTMLEditorKit and set the attributes for the specific "a" tag but then you would have to try and find it in there...good luck!
Or of course you could modify the HTML file prior to loading it into the editor... -
Html files, images and JEditorPane
Hello all,
I've got some HTML file that need be displayed in a JEditorPane. Those HTMLs contain image references and I'm using relative paths to those jpegs, for example:
<img src="image.GIF">
...where image.gif is in the same folder as the HTML file that contains the reference. Now I'm displaying this HTML file inside a JEditorPane and I get only a placeholder instead of the image; only text gets displayed properly.
Here's how I'm constructing the JEditorPane instance:
pane = new JEditorPane();
pane.setEditable(false);
pane.setContentType("text/html");
HTMLEditorKit kit = new HTMLEditorKit();
kit.createDefaultDocument();
pane.setEditorKit(kit);and later...
try {
URL u = new URL("file", "localhost", ivHelpPath);
pane.setPage(u);
} catch (IOException iox) {
}I saw on some other thread that I should be setting the document's base URL for the reference I get from getDocument(), but that does not seem to work when I use "http://localhost/" to make my URL object.
So... help! :)
Thanks much.Not sure what you're trying to do with new URL( "file" "localhost", ...
Try this code and see if it helps you - display a page that already exists though - perhaps that's the diff?
JTextPane() jtp = new JTextPane(); //JEditorPane();
jtp.setEditable( false );
JScrollPane jsp = new JScrollPane( jtp,
JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED );
( ( HTMLEditorKit ) ( jtp.getEditorKit() ) ).setLinkCursor( new Cursor( Cursor.HAND_CURSOR ) );
jtp.addHyperlinkListener( new HyperlinkListener() {
public void hyperlinkUpdate( HyperlinkEvent hle ) {
try {
if ( hle.getEventType() == HyperlinkEvent.EventType.ACTIVATED )
jtp.setPage( hle.getURL() );
} catch( Exception e ) {
// do something;
});... There's also code here that will activate hyperlinks which you may or may not want. But this will display embedded .gif files. -

Thanks
RamRam,
I have had printing problems too a year and a half ago. I used all printing apis of java and I still find that it is something java lacks. Now basically you can try autosense. To check whether your printer is capable of printing the docflavor use this PrintServiceLookup.lookupPrintServices(flavor, aset); . If it lists the printer then he can print the document otherwise he can't. I guess that is why you get the error.

I want to display a HTML file that is stored locally on my machine.
Hello,
I am having a problem with my paths (I believe). I have created a JEditorPane that reads in a HTLM page. If the page is form the web it works fine:
page_jep.setPage("http://www.google.com");However I want to display a HTML file that is stored locally on my machine.
I have tried the following but cant get it to find the stored page:
page_jep.setPage("file:///index.htm");
java.io.FileNotFoundException: \index.htm (The system cannot find the file specified)I have tried putting the index file in both the root directory ( C ) and also the same place as where the class files are.
Any help will be gratefully received,
Harold ClementsNope, I have tried it:
page_jep.setPage("file://c:\\index.htm");Gives me:
java.net.UnknownHostException: c
