Need help for using doctrine entity and Symfony 2 libraries in an extension

[eftakhairul]

Hi,

I am making an module extension named civicrm voice broadcast (extension is not any CMS specified and CiViCRM version is 4.4.5). I want to use Doctrine Entity for DB persistence and Symfony 2 libraries. Can anybody help me with code snippets or any implemented extension with Doctrine as well as Symfony 2 libraries?

As discussed, you should review the CiviHR extensions to see how they do it. If you have more specific questions that would be better.
