I had created a new app in grails, and my colleague was trying to access this app after copying this folder to his local machine.

When he created a fresh application, grails created the application, however he was not able to run the application. The same was case with the copied application.

Section 3: How to play audio files in HTML5 The sweetest and simplest way to play audio files is HTML5. You will agree with me after seeing the following code: <audio src="audiotest.ogg" autoplay>   Your browser does not support the <code>audio</code> element. </audio> Was I right in guessing your reaction?
