Doctrine2: What is wrong with the association between these entities? - doctrine

Question

I am trying to work through simple examples to see all the changes in Doctrine2.
Please take a look at the following entity snippets:
VCat.php
namespace Application\Models;
/**
* #Entity
* #Table(name="v_cat")
*/
class VCat
{
/**
* #Id #Column(type="bigint")
* #GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #OneToMany(targetEntity="VScat", mappedBy="vCat") )
*/
private $vScats;
namespace Application\Models;
VScat.php
namespace Application\Models;
/**
* #Entity
* #Table(name="v_scat",indexes={#index(name="FK_v_scat",columns={"vcatid"})})
*/
class VScat
{
/**
* #Id #Column(type="bigint")
* #GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ManyToOne(targetEntity="VCat", inversedBy="vScats")
* #JoinColumn(name="vcatid", referencedColumnName="id")
*/
private $vCat;
vcatid is the Foreign Key column in table v_scat
This is the query I am trying to run:
$categories = Zend_Registry::get('em')
-> createQuery('select c.name, sub.name as sub_name from \Application\Models\VCat c JOIN c.VScat sub WHERE sub.active = 1 and c.active = 1 and c.id = sub.vcatid')
-> getResult();
And this is the error:
(string:130) [Semantical Error] line 0, col 69 near 'sub WHERE sub.active': Error: Class Application\Models\VCat has no association named VScat
It seems right, but I am obviously missing something.
UPDATE Now I get this error, which refers to the table column name in mysql. Is that incorrect? I thought I needed to tell Doctrine somehow that this property belongs to this field in the DB.
Error: Class Application\Models\VScat has no field or association named vcatid

It's the property on VCat you need to reference not the entity type.
JOIN c.VScat sub
should be:
JOIN c.vScats sub
