Make a href="" clickable in labels/messages?

Question

Is it possible to add a click-sensitive URL in a message dialog?
I add HTML formatted text as the message via JOptionPane.showMessageDialog(). adding "<a href=" tags are rendered correctly (they are displayed blue and underlined) but nothing happens when i click in this "link" ... of course(?).
is it possible to make such a link "click-sensitive" so that the user can click on this link in the dialog and the URL is opened in the browser (or at least in a Java component capabale of displaying HTML web sites)?

This is definitely not the end solution to your problem, but maybe somewhat atleast....
Btw, if possible I'd like to see the code you use to make an url link.
package pax.ui.resources;
import java.io.IOException;
* A class to execute an URL in a browser.
* Under Unix, the system browser is hard-coded to be 'netscape'.
* Netscape must be in your PATH for this to work. This has been
* tested with the following platforms: AIX, HP-UX and Solaris.
* Under Windows, this will bring up the default browser under Windows,
* usually either Netscape or Microsoft IE. The default browser is
* determined by the OS. This has been tested under Windows 95/98/NT/XP.
* Used as: PaxBrowserControl.executeURL("url");
* Note: It's a must to include the url type, either "http://" or "file://".
* Code written by Unknown, edited by Martin Ulfvik, aka Paximir.
public class PaxBrowserControl
     // Used to identify the Windows platform.
private static final String WIN_ID = "Windows";
// The default browser under Windows.
private static final String WIN_PATH = "rundll32";
// The flag to display an url under Windows.
private static final String WIN_FLAG = "url.dll,FileProtocolHandler";
// The default browser under Unix.
private static final String UNIX_PATH = "netscape";
// The flag to display an url under Unix.
private static final String UNIX_FLAG = "-remote openURL";
     * Tries to run a given argument, (String url),
     * as an adress in an open or new browser.
public static void executeURL(String aURL)
     Process process;
String cmd = null;
String os = System.getProperty("os.name");
try     
     // Checks if the operating system is Windows.
if(os != null && os.startsWith(WIN_ID))
cmd = WIN_PATH + " " + WIN_FLAG + " " + aURL;
process = Runtime.getRuntime().exec(cmd);
else
// Under Unix, Netscape has to be running for the "-remote"
// command to work. So, we try sending the command and
// check for an exit value. If the exit command is 0,
// it worked, otherwise we need to start the browser.
cmd = UNIX_PATH + " " + UNIX_FLAG + "(" + aURL + ")";
process = Runtime.getRuntime().exec(cmd);
try
// Waits for exit code and checks if the command worked.
// 0 = worked. If its not 0 startup of browser is neededed,
if(process.waitFor() != 0)
cmd = UNIX_PATH + " " + aURL;
process = Runtime.getRuntime().exec(cmd);
catch(InterruptedException aInterruptedException)
System.err.println("Error bringing up browser, command=" + cmd);
System.err.println("Caught: " + aInterruptedException);
// When a browser could not be executed.
catch(IOException aIOException)
System.err.println("Could not invoke a browser, command=" + cmd);
System.err.println("Caught: " + aIOException);
     // End of executeURL(String).
     // End of class PaxBrowserControl.
     * Main method for Debugging and Testing purposes.
     * Just paste the method into the PaxBrowserControl class and uncomment it.
/*     public static void main(String args[])
          // Runs the url "http://java.sun.com" in an open or new browser.
          executeURL("http://java.sun.com");
          // End of method main(String).
