The following code requires JHyperLink to be added to your build path   JHyperlink stackOverflow   new JHyperlink  Click HERE                     https   www stackoverflow com      JComponent   messageComponents   new JComponent     stackOverflow     JOptionPane showMessageDialog null  messageComponents   StackOverflow                   JOptionPane PLAIN MESSAGE     Note that you can fill the JComponent array with more Swing components   Result

Maybe use JXHyperlink from SwingX instead  It extends JButton  Some useful links   Class JXHyperlink SwingX  Consider JXHyperlink As An Alternative To Buttons

Update I ve tidied up the SwingLink class further and added more features  an up-to-date copy of it can be found here  https   bitbucket org dimo414 jgrep src tip src grep SwingLink java     McDowell s answer is great  but there s several things that could be improved upon  Notably text other than the hyperlink is clickable and it still looks like a button even though some of the styling has been changed hidden  While accessibility is important  a coherent UI is as well   So I put together a class extending JLabel based on McDowell s code  It s self-contained  handles errors properly  and feels more like a link   public class SwingLink extends JLabel     private static final long serialVersionUID   8273875024682878518L    private String text    private URI uri     public SwingLink String text  URI uri       super        setup text uri          public SwingLink String text  String uri       super        setup text URI create uri           public void setup String t  URI u       text   t      uri   u      setText text       setToolTipText uri toString         addMouseListener new MouseAdapter           public void mouseClicked MouseEvent e            open uri                 public void mouseEntered MouseEvent e            setText text false                 public void mouseExited MouseEvent e            setText text true                           Override   public void setText String text       setText text true          public void setText String text  boolean ul       String link   ul     lt u gt   text   lt  u gt     text      super setText   lt html gt  lt span style   color   000099    gt        link   lt  span gt  lt  html gt         this text   text         public String getRawText        return text         private static void open URI uri        if  Desktop isDesktopSupported            Desktop desktop   Desktop getDesktop          try           desktop browse uri           catch  IOException e            JOptionPane showMessageDialog null               Failed to launch the link  your computer is likely misconfigured                 Cannot Launch Link  JOptionPane WARNING MESSAGE                 else         JOptionPane showMessageDialog null             Java is not able to launch links on your computer               Cannot Launch Link   JOptionPane WARNING MESSAGE                 You could also  for instance  change the link color to purple after being clicked  if that seemed useful   It s all self contained  you simply call   SwingLink link   new SwingLink  Java    http   java sun com    mainPanel add link

I d like to offer yet another solution  It s similar to the already proposed ones as it uses HTML-code in a JLabel  and registers a MouseListener on it  but it also displays a HandCursor when you move the mouse over the link  so the look amp feel is just like what most users would expect  If browsing is not supported by the platform  no blue  underlined HTML-link is created that could mislead the user  Instead  the link is just presented as plain text  This could be combined with the SwingLink class proposed by  dimo414   public class JLabelLink extends JFrame    private static final String LABEL TEXT    For further information visit    private static final String A VALID LINK    http   stackoverflow com   private static final String A HREF     lt a href      private static final String HREF CLOSED       gt    private static final String HREF END     lt  a gt    private static final String HTML     lt html gt    private static final String HTML END     lt  html gt     public JLabelLink         setTitle  HTML link via a JLabel        setDefaultCloseOperation JFrame DISPOSE ON CLOSE        Container contentPane   getContentPane        contentPane setLayout new FlowLayout FlowLayout LEFT         JLabel label   new JLabel LABEL TEXT       contentPane add label        label   new JLabel A VALID LINK       contentPane add label       if  isBrowsingSupported              makeLinkable label  new LinkMouseListener                pack       private static void makeLinkable JLabel c  MouseListener ml        assert ml    null      c setText htmlIfy linkIfy c getText           c setCursor new java awt Cursor java awt Cursor HAND CURSOR        c addMouseListener ml      private static boolean isBrowsingSupported         if   Desktop isDesktopSupported              return false            boolean result   false      Desktop desktop   java awt Desktop getDesktop        if  desktop isSupported Desktop Action BROWSE             result   true            return result      private static class LinkMouseListener extends MouseAdapter         Override     public void mouseClicked java awt event MouseEvent evt            JLabel l    JLabel  evt getSource            try               URI uri   new java net URI JLabelLink getPlainLink l getText                   new LinkRunner uri   execute              catch  URISyntaxException use                throw new AssertionError use          l getText       NOI18N                    private static class LinkRunner extends SwingWorker lt Void  Void gt         private final URI uri       private LinkRunner URI u            if  u    null                throw new NullPointerException                      uri   u              Override     protected Void doInBackground   throws Exception           Desktop desktop   java awt Desktop getDesktop            desktop browse uri           return null              Override     protected void done             try               get              catch  ExecutionException ee                handleException uri  ee             catch  InterruptedException ie                handleException uri  ie                        private static void handleException URI u  Exception e            JOptionPane showMessageDialog null   Sorry  a problem occurred while trying to open this link in your system s standard browser     A problem occured   JOptionPane ERROR MESSAGE            private static String getPlainLink String s        return s substring s indexOf A HREF    A HREF length    s indexOf HREF CLOSED         WARNING   This method requires that s is a plain string that requires   no further escaping private static String linkIfy String s        return A HREF concat s  concat HREF CLOSED  concat s  concat HREF END        WARNING   This method requires that s is a plain string that requires   no further escaping private static String htmlIfy String s        return HTML concat s  concat HTML END              param args the command line arguments     public static void main String   args        SwingUtilities invokeLater new Runnable               Override         public void run                 new JLabelLink   setVisible true

If  lt a href  link  gt  doesn t work  then    Create a JLabel and add a MouseListener  decorate the label to look like a hyperlink  Implement mouseClicked   event In the implementation of mouseClicked   event  perform your action   Have a look at java awt Desktop API for opening a link using the default browser  this API is available only from Java6

You might try using a JEditorPane instead of a JLabel   This understands basic HTML and will send a HyperlinkEvent event to the HyperlinkListener you register with the JEditPane

You can do this using a JLabel  but an alternative would be to style a JButton  That way  you don t have to worry about accessibility and can just fire events using an ActionListener     public static void main String   args  throws URISyntaxException       final URI uri   new URI  http   java sun com        class OpenUrlAction implements ActionListener          Override public void actionPerformed ActionEvent e            open uri                     JFrame frame   new JFrame  Links        frame setDefaultCloseOperation JFrame EXIT ON CLOSE       frame setSize 100  400       Container container   frame getContentPane        container setLayout new GridBagLayout         JButton button   new JButton        button setText   lt HTML gt Click the  lt FONT color    000099   gt  lt U gt link lt  U gt  lt  FONT gt               to go to the Java website  lt  HTML gt         button setHorizontalAlignment SwingConstants LEFT       button setBorderPainted false       button setOpaque false       button setBackground Color WHITE       button setToolTipText uri toString         button addActionListener new OpenUrlAction         container add button       frame setVisible true          private static void open URI uri        if  Desktop isDesktopSupported            try           Desktop getDesktop   browse uri           catch  IOException e       TODO  error handling            else      TODO  error handling
