Insert String to JTextPane as hyperlink

Question

Hi,
I have a JTabbedPane with 2 tabs, on each tab is one panel.
On first pannel I add JTextPane and I would like to insert in this JTextPane some hyperlinks.
I found some examples in forum, but doesn't work for me.
Could somebody help me ?
Thank's.
Here is my code :
JTextPane textPane = new JTextPane();
textPane.setPreferredSize(new Dimension(500,300));
HTMLEditorKit m_kit = new HTMLEditorKit();
textPane.setEditorKit(m_kit);
StyledDocument m_doc = textPane.getStyledDocument();
textPane.setEditable(false); // only then hyperlinks will work
panel1.add( textPane,BorderLayout.CENTER); //add textPane to panel of
//JTabbedPane
String s = new String("http://google.com");
SimpleAttributeSet attr2 = new SimpleAttributeSet();
attr2.addAttribute(StyleConstants.NameAttribute, HTML.Tag.A);
attr2.addAttribute(HTML.Attribute.HREF, s);
try{
m_doc.insertString(m_doc.getLength(), s, attr2);
}catch(Exception excp){};
The String s is displayed like text not like hyperlink..

Hi , You can take a look at this code , this code inserts a string into a StyledDocument in a JTextPane as a hyperlink and on clicking fires the URL on the browser.

                               // Build a command string which looks like "browser1 "url" || browser2 "url" ||..."
                               StringBuffer cmd = new StringBuffer();
                               for (int i = 0 ; i < browsers.length ; i++)
                                    cmd.append((i == 0  ? "" : " || " ) + browsers[i] +" \"" + url + "\" ");
                               rt.exec(new String[] { "sh", "-c", cmd.toString() });
               catch (Exception ex)
                    ex.printStackTrace();
             public void actionPerformed(ActionEvent e){
                     execute();
}Here , what I have done is associated a mouseListener and a mouseMotionListener with the JTextPane and I have created the hyperlink look with a Style of blue color and underline and have added the LINK_ATTRIBUTE to that Style which takes care of listening to mouse clicks and mouse motion.
The browser can be started in windows using the default FileProtocolHandler using rundll32 and in Unix/Sun we have to take a wild guess at which browser could be installed , the first browser encountered is started , in Mac open command takes care of starting the browser.
Hope this is useful.
