  2. Dear Sir/Madam,

    I want to wrtie a sudoku program and need to read numbers from mobile.But I have a problem.

    I am trying to read keypad of mobile in gamecanvas with netbeans. The code is :
    protected void keyPressed(int keyCode){
    if (keyCode == KEY_NUM1) { something }
    if (keyCode == KEY_NUM2) {something }
    if (keyCode == KEY_NUM3) { something }
    In IDE emulator it can read 2,4,5,6,8 keys and in my mobile(SonyEricsonw880) only 1,3 keys work.
    How can I solve the problem?
    Yours faithfully

    Cordial saludo.
    Me gustaría saber si usted podría darme información a cerca de cómo establecer conexiones en J2ME, entre un celular y una página https y visualizar en la pantalla la información, pues he buscado e intentado de varias maneras, pero no he logrado el resultado que necesito. Estoy trabajando con NetBeans.

    De antemano agradezco la colaboración que me pueda brindar.

    Saludos cordiales.

  4. Jenny. Hace mucho tiempo que no he tocado J2ME.

    La forma el utilizar un HttpConnection para leer la pagina. Si quieres visualizarla vas a tener que interpretarla. Lo otro es abrir el browser por medio de un ContentHandler.
