JOptionPane isn't showing

JOptionPane is not showing.. Please check my code:

public void actionPerformed(ActionEvent e) {
     // TODO Auto-generated method stub
     //if (e.getActionCommand().equals("Ok")){
     if ( e.getActionCommand().equals(btnOk) ){
              if(connect(txtUser.getText(), txtPass.getText() ) ) {
                  JOptionPane.showMessageDialog(null, "WARNING", "Valid user!", JOptionPane.INFORMATION_MESSAGE);
              }
              else {
                        System.out.print("Wrong password!");
              }

     }
 }

my connect method, please check this.

public boolean connect(String usr, String pwd){

     try {
         Class.forName("com.mysql.jdbc.Driver");
         connection = DriverManager.getConnection(
                     "jdbc:mysql://localhost:3306/USERS", "root", "root" );
          PreparedStatement ps = 
                  connection.prepareStatement( "SELECT lname, fname FROM employees where fname=? and lname =?" );
          ps.setString(1,usr);
          ps.setString(2,pwd);

         resultSet = ps.executeQuery();


       if(resultSet.next()) {
                return true;
       }

     } catch (Exception e) {
         e.printStackTrace();
     }

     return false;
 } // end of connect method

I don't know what's wrong with my code. any help would be appreciated. thanks

If it does not print Wrong password! it means that it does not pass the e.getActionCommand().equals(btnOk) line. Make sure btnOk is a String and it is the String you are looking for.

If it prints Wrong password, it is straighforward why this happens.

btnOk sounds like a button to me, not a String (but without any extra code snippets we just have to guess that), so be careful not to test equality between the String actionCommand and a button.
