mongodb with zf2 gives an error The class was not found in the chain configured namespaces - mongodb

Question

I know I miss something in the configuration.
Can anyone provide the steps for this configuration
Mongo is running in my terminal properly.
when connect with zend in sequential way it works . but in procedural way it gives error.
this is global config file
'driver' => array(
'odm_default' => array(
'class' => 'Doctrine\Common\Persistence\Mapping\Driver\MappingDriverChain',
'drivers' => array()
)
),
when I write
$dm = $this->getServiceLocator()->get('doctrine.documentmanager.odm_default');
$user = new User();
$user->setName("Gembul");
$dm->persist($user);
persist then it gives class not found error

Answer 1

When I found this error then I modify my database class means that change the comments in my model class in document section .
use Doctrine\ODM\MongoDB\Mapping\Annotations as ODM;
/**
* Description of User
*
* #author kiwitech
*/
/** #ODM\Document(collection="user") */
class Users
{
protected $dm;
/** #ODM\Id */
private $_id;
/** #ODM\Field(type="string") */
private $_first_name;
/** #ODM\Field(type="string") */
private $_last_name;
/** #ODM\Field(type="string") */
private $_login_name;
/** #ODM\Field(type="string") */
private $_email;
/** #ODM\Field(type="string") */
private $tp_id;
/** #ODM\Field(type="string") */
private $_is_active;
/** #ODM\Field(type="string") */
private $_role_id;
function get_id() {
return $this->_id;
}
function get_first_name() {
return $this->_first_name;
}
function get_last_name() {
return $this->_last_name;
}
function get_login_name() {
return $this->_login_name;
}
function get_email() {
return $this->_email;
}
function getTp_id() {
return $this->tp_id;
}
function get_is_active() {
return $this->_is_active;
}
function get_role_id() {
return $this->_role_id;
}
function set_id($_id) {
$this->_id = $_id;
}
function set_first_name($_first_name) {
$this->_first_name = $_first_name;
}
function set_last_name($_last_name) {
$this->_last_name = $_last_name;
}
function set_login_name($_login_name) {
$this->_login_name = $_login_name;
}
function set_email($_email) {
$this->_email = $_email;
}
function setTp_id($tp_id) {
$this->tp_id = $tp_id;
}
function set_is_active($_is_active) {
$this->_is_active = $_is_active;
}
function set_role_id($_role_id) {
$this->_role_id = $_role_id;
}
}
then I easily solve this bug :)
