Unable to embed templates in Symfony2

Question

I want to add some content in Symfony 2. I do it as follow:

{% embed "sub.html.twig" %}
{% block sourcecode %}
    <div class="tab-pane" id="5" name="textsource">
        <textarea id="source" class="span6"></textarea>
    </div>
{% endblock %}
{% endembed %}

When I run this then it is showing that it is unable to find sub.html.twig. What should I do?? And in sub.html.twig I am using the following code:

{% embed 'AcmeTaskBundle:Default:index.html.twig' with {} %}

Please try to change

{% embed "sub.html.twig" %}

to

{% embed "AcmeTaskBundle:Default:sub.html.twig" %}
