We would like to have some material on how to write applications which can push information to the BlackBerry handheld. We have materials which gives the basic architecture and outline but nothing about coding. Can anyone help us, if possible with some sample codes also ?

Thanks in advance

Hi Rajeev.

It depnds on what you would like to push. My book explains how to push out a channel, etc. and the sample PHP code is included in the download. I would start there to see the technique.

Cheers.

Hi Craig,

Thank you for the reply.

I went through the details for Push in Chapter 11 and 12 in the Professional BlackBerry download.

We basically want to integrate an existing application with BlackBerry. We are looking at automatically popping up an alert to the user in his BlackBerry when there is an update in one of our tables in the Database / App server. When the user clicks on the alert on his BlackBerry he will be redirected to an URL which will prompt him for further actions.

Are there any classes / methods which will help us do this ? Is any reference to this scenario available in the BlackBerry Professional download, if possible with sample codes ? We are using BlackBerry JDE 4.0.2 and also have the MDS and Device simulators.

Thanks in advance
Regards,

Rajeev

Hi Rajeev.

It sounds like you could achieve this with a Channel. If you look at the sample code you will see a PHP file which allows you to push a Reliable Channel. When you do this you have options to force a popup on the screen (these extra commands are detailed in the book). When the user clicks OK, the channel is not invoked however, but the user can simply click on it to be directed to the URL.

I hope that this helps.

Craig.
