opening hyperlinks in a JEditorPane

[dunkymunky]

I've got a JEditorPane that is correctly displaying HTML hyperlinks, but all it does is display them, how can I make it so that when someone clicks on this hyperlink, it opens up their default web browser and opens the correct page?

This is the code I have so far:

public interface HyperLinkListener {
  public void hyperlinkUpdate(HyperlinkEvent e);
} 
public void hyperlinkUpdate(HyperlinkEvent evt) {
 
    if (evt.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
      try {
        LinksList.setPage("http://www.facebook.com");        
      }
      catch (Exception e) {        
      } 
    }
}
 
    private void links(){
 
                    LinksList.addHyperlinkListener(this);
        String[] linksarray = new String[10];
        int i = 0;
        LinksList.setContentType("text/html");
 
        try{    
        BufferedReader links = new BufferedReader (new FileReader("links.txt"));
 
        while(i<10){
            linksarray[i] = links.readLine();
            i++;
 
        }//end while
 
        i=0;        
        while(linksarray[i]!=null){
            LinksList.setText(linksarray[i]+"\n");
 
 
            i++;
        }//end while
    }//end try
 
    catch (FileNotFoundException e){
    errorMessageDialogue(e.getMessage());
    }//end catch
 
    catch (IOException e){
    errorMessageDialogue(e.getMessage());
    }//end catch
 
 
    }//end links

The JEditorPane is called LinksList, it reads HTML code from a file called links.txt and then displays it, with the standard blue colour and underlining...can anyone suggest what the code might be?

Why are you defining your own HyperLinkListener interface? It won't be called
by your JTextPane. Use the one supplied by the core classes. Once you've
got the HTTPHyperLinkEvent you can get the URI that was clicked. Give that
URI to the Desktop.browse() method and you're done.

hmm...thanks for the reply...but still not sure how to go about it...?

Did you read the API documents w.r.t. the relevant classes or did you expect
boiler plate code?

i've gone all over the API, and looked at other examples on the internet, but just cant seem to get it working properly...boiler plate code would be much helpful (im assuming boiler plate code is basic, skeleton code :P )

Ok, again: the JEditorPane fires an event when a hyperlink is clicked. Your
hyperlink listeners receive that event. The event captures the URI that has been
clicked on. A Desktop object can fire the system's default browser given a
URI.

So all you have to do is register a HyperLinkListener implementation to the
JEditorPane (don't define your owen HyperLinkListener interface because that
won't work). When it receives a HyperLinkEvent it grabs the URI from it and
passes it to the Desktop class.
