Hi,

I'm new to mobile web development.
During my first exercise (this tutorial) I got the following error,

XML Parsing Error: junk after document element
Location: http://localhost/mobile/
Line Number 2, Column 1:Warning: file_get_contents(json/DeviceAtlas.json) [function.file-get-contents]: failed to open stream: No such file or directory in C:\wamp\www\mobile\Mobi\Mtld\DA\Api.php on line 123
^

If any one knows why its appearing please help me to sort out this..
Also I'm using PHP and Apache higher versions than the minimum requirements.
If there is any specific extensions to be ON before we use the coding please let me know..
Please Help!
Thank you.
