Pagina a partir de JMenuItem de novo

Tenho o seguinte codigo para abrir uma pagina de internet pelo JMenuItem (não sei se falta alguma coisa):

…

menuItem = new JMenuItem("Pesquisa");
  menuItem.setMnemonic(KeyEvent.VK_P);
  menuItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_5, ActionEvent.ALT_MASK));
  
  menuItem.addActionListener(
      new ActionListener() {
         public void actionPerformed(ActionEvent event) {
             Runtime.getRuntime().exec("start iexplore http://www.google.com.br");
       }
 
  }
                   
  );   

  menu.add(menuItem);

…

Dá o seguinte erro na compilação: “unreported exception java.io.IOException; must be caught or declared to be thrown Runtime.getRuntime().exec(“start iexplore http://www.google.com.br”);”

Alguém pode dá uma mão aí?

Tente fazer isso:

try

{

Runtime.getRuntime().exec(“start iexplore <a href="http://www.google.com.br">http://www.google.com.br</a>”);

}

catch(Exception e)

{

e.printStackTrace();

}

menuItem.addActionListener(

new ActionListener() {
 
          public void actionPerformed(ActionEvent event) {

             try 
             { 
                Runtime.getRuntime().exec("start iexplore http://www.google.com.br"); 
             } 
             catch(Exception e) 
             { 
             e.printStackTrace(); 
             }
         
         }
 
     }
                   
  );

Assim, eu não tive problemas de compilação, mas na hora de executar o programa (quando eu dou um clique no JMenuItem) aparece as seguintes mensagens (e não realiza a tarefa):

Para WinXP:

try
{
	Runtime.getRuntime().exec(new String[] {"cmd.exe","/c", "start", "http://www.google.com.br"});				
}
catch(Exception ex)
{
	ex.printStackTrace();
}

Para Win9x

try
{
	Runtime.getRuntime().exec(new String[] {"command.com","/c", "start", "http://www.google.com.br"});				
}
catch(Exception ex)
{
	ex.printStackTrace();
}
