Question: I would like to use Doctrine 2 in ZF2 project. I have done some researches. I found this:
<http://www.jasongrimes.org/2012/01/using-doctrine-2-in-zend-framework-2/>

Unfortunately, I don't have CURL nor composer installed. And when I tried to install CURL first. I had errors i don't manage to solve.

Is there an easy solution to integrate Doctrine 2 in ZF2 ?

Answer: 
I spent a lot of days trying to find a good solution to integrate Doctrine 2 into ZF2. Finally, I managed to do it with this skeleton application: <https://github.com/iwalz/zf2-doctrine2-getting-started>

It has a very good readme, if you follow the steps, success is guaranteed!
You have the official Doctrine ZF2 Module written by Doctrine team

<https://github.com/doctrine/DoctrineModule>

Composer or CURL are a easy way of download that sources and register the namespace. You can do the same downloading the sources and registering the module
