title: Unable to use Propel 2 (Class not found)
body: <p>I'm tryng from several days to setup and use Propel now 2.0. PHP version is 5.4.4-14+deb7u5</p>
  
  <p>What I have done:</p>
  
  <p>0) Fresh LAMP with a folder "test" in /var/www</p>
  
  <p>1) Composer.json with</p>
  
  <pre><code>{
      "require": {
          "propel/propel": "2.0.*@dev"
      }
  }
  </code></pre>
  
  <p>(also tried with the alpha indicated in home page, no success, download but i cannot use)</p>
  
  <p>2) It download all necessary files.</p>
  
  <p>3) I can launch "vendor/bin/propel" and it exit after some green text.</p>
  
  <p>4) I create the schema.xml with foreign keys indicated in <a href="http://propelorm.org/documentation/02-buildtime.html" rel="nofollow">http://propelorm.org/documentation/02-buildtime.html</a></p>
  
  <p>5) I set up buildtime.cconfiguration</p>
  
  <p>6) I can create the <code>sql:build</code> and the model:build (I find the bookstore.sql in generated-sql and the classes in generated-classes)</p>
  
  <p>7) <strong>I CANNOT insert the sql</strong>. I launch <code>sql:insert</code>, no error at screen but no insert in database (connection/password is okay, double checked).</p>
  
  <p>8) I load myself SQL in database.</p>
  
  <p>9) I create an index.php with this:</p>
  
  <pre><code>&lt;?php
  // setup the autoloading
  require_once 'vendor/autoload.php';
  use Propel\Runtime\Propel;
  use Propel\Runtime\Connection\ConnectionManagerSingle;
  $serviceContainer = Propel::getServiceContainer();
  $serviceContainer-&gt;setAdapterClass('bookstore', 'mysql');
  $manager = new ConnectionManagerSingle();
  $manager-&gt;setConfiguration(array (
    'dsn'      =&gt; 'mysql:host=localhost;dbname=my_db_name',
    'user'     =&gt; 'my_db_user',
    'password' =&gt; 's3cr3t',
  ));
  $serviceContainer-&gt;setConnectionManager('bookstore', $manager);
  
  echo 'All ok, for now...';
  
  $author = new Author();
  $author-&gt;setFirstName('Jane');
  $author-&gt;setLastName('Austen');
  $author-&gt;save();
  
  /* /end of php file */ 
  </code></pre>
  
  <p>The echo is printed normally but next row script exit with error 500 and in Apache log I read "Class author not found".</p>
  
  <p>Is there some other config to adjust other than indicate in the guide?</p>
