Hi all,

I am trying to follow the following documentation page: link

I have at the moment local audio files locates at my folder: /home/remie/Downloads/Audio

Below is my example:

I use the following source tag: src="/home/remie/Downloads/Audio/error_01.wav" and activate the controls with controls="true"

However it displays a set of audio controls but i cannot play my sound file.

Should the sound file exist in the Java Project or can it reside somewhere else?

Hi rmalik,

The src attribute will accept a url relative to the ServletContext. (the root of your webapp) This said, you can still use a file located outside of your ServletContext by using the setContent() method on Audio, and passing the File directly:

myAudio.setContent(new AAudio(new File("D:\\test\\file.mp3")));

(test here on windows, but works the same on linux)

You can do this in a composer, or by returning the AAudio in a getter of your viewModel in MVVM

Hi MDuchemin,

Thanks you for your reply! It was exactly what i was looking for!

However i have still a small question. I noticed that i have to place the audio tag in my zul. I would really like just to create a new Audio object in my VM (Like Audio audio = new Audio()).

When i do this and i debug the line i see that my page is null:

if (_page != null) {
            getAttachedUiEngine().addResponse(key, response, priority);
        } else if (response.getDepends() != this) {
            final UiEngine uieng = getCurrentUiEngine();
            if (uieng != null)
                uieng.addResponse(key, response);
        }

Do you know how i can attach my current page to the Audio component?

I was to quick to ask. You can set it with audio.setPage(Executions.getCurrent().getDesktop().getPage("indexPage")); Thanks again MDuchemin.

yes you have to add a component to a page either as a root component via setPage() or as a child below another component via setParent(). This is the equivalent of adding the component in a zul page. the result will be the same.
