copied!<p>You first need to register for the Blackberry Push service <a href="https://www.blackberry.com/profile/?eventId=8121">here</a></p> <p>They will then send you an email in a couple of days with the app ID, port and push initiator password etc.</p> <p>On the client side you can then listen for push requests:</p> <pre><code>var port = 100; // Change this to the port you received from RIM var appId = "The app ID you received from RIM"; var serverUrl = "http://pushapi.eval.blackberry.com"; var max = 100; var wakeUpPage = "index.html"; function init() { var ops = {port : port, appId : appId, serverUrl : serverUrl, wakeUpPage : wakeUpPage, maxQueueCap : max}; blackberry.push.openBISPushListener(ops, pushReceive, pushRegister, simChange); } function pushReceive(data) { try { var message = blackberry.utils.blobToString(data.payload); return 0; } catch(err) { } } function pushRegister(status) { if (status == 0) { alert("success"); } else if (status == 1) { alert("network error"); } else if (status == 2) { alert("rejected by server"); } else if (status == 3) { alert("invalid parameters"); } else if (status == -1) { alert("general error"); } else { alert("unknown status"); } } window.onload = function() { init(); } </code></pre> <p>Also make sure you have <code><feature id="blackberry.push" /></code> and <code><feature id="blackberry.utils" /></code> in your config.xml.</p> <p>What I also noted was that when the app is closed the pushReceive() doesn't get called. You can bypass this by running the app in the background: </p> <pre><code>function handleExit() { blackberry.app.requestBackground(); } blackberry.app.event.onExit(handleExit); </code></pre> <p>and use <code>blackberry.app.requestForeground();</code> to bring app to the front.</p> <p>The other thing which took me a while to figure out was that it might take a while before pushRegister() is called (this registers the PIN on BIS). So make sure this gets called otherwise you will never be able to receive push messages.</p>
