Gostaria de esclarecer uma duvida em relação a envio de dados para servlet.
estou fazendo um trabalho para iniciante em javaweb no netbeans que é para fazer uma tela de login e senha que tenho que enviar estas informações para uma servlet e ela tem que validar, fiz de um jeito mas queria saber se tem uma outra maneira para eu fazer sem ter que habilitar o comentário do protected void processRequest(HttpServletRequest request, HttpServletResponse response.
segue os dados:
