    Suggestion regarding j2me http request

    I'm doing j2me stock price applicaton. I want to give a http request to the server and get the price from server. I got the price.

    But my question is when i click refresh command, i want to update the price for every 5 seconds.

    1. how can i give continous http request for every 5 second.?

    2. when i connect to server, always asking permission to connect the server, how can i avoid that dialog..?

    Note : I'm using J2MEPolish TableItem to update the prics.

    Help me,
    kumar.

    Code:
    if (c == refresh) {
                timer = new Timer();
                timertask =  new MyTimerTask();
                timer.schedule(timertask,1000,1000);
            }
    In run() method of the timer class I have http connection to get the price.

    Code:
            public void run() {
                downloadPage(url);      
            }
    For every sec, its asking permission dialog to connect http, and values also not changing. how to solve this?

    please help me,
    kumar

    Actually device should not ask for it, i have designed so may applications that connect to server n no of times at first time only device asks and once it is set to "allow for session" it wont ask any further on which device you are testing have you tried testing on other devices .

    What i request you is increase timer to to five minute or more value test it once again .if the problem gets solved then it is the issue of cache being stored in the mobile else problem might be at server side

    Re: Suggestion regarding j2me http request

    Thanks for ur reply,

    Another doubt..?

    When i perform http connection in command handling listerner like,

    Code:
     if (cmd == cmdSend) {
                   sendHttpPost(EnteredID); 
    			}
    I got this error
    Warning: To avoid potential deadlock, operations that may block, such as
    networking, should be performed in a different thread than the
    commandAction() handler
    I know this is come only in emulator not in real devices. Right now, My testing team is testing apps in emulator only.

    how can i avoid this in emulator..?

    is this possible .?

    use threads in your application ,by Doing that above warning would not be shown and even it is good design practice also help your application to work on devices smoothly

    keep code as

    new Httppost().start();

    }
