    Real devices on real
    networks might have root certificates that are specific to the manufacturer or
    wireless carrier. Check with your device manufacturer or wireless carrier for
    details on signed MIDlets.

    When running my
    MIDlet, a security alert is displayed. Why can’t I dismiss the alert?

    You are probably
    trying to access a protected API (for example, opening a connection) from your
    commandAction() method, which is locking the UI thread. Access
    protected APIs from a separate thread. Refer to the NetworkDemo for an example
    on how this can be done.
