Whats wrong with this Hibernate question?

Hello!

I have implemented Hibernate as a databas layer and every thing seems to work well.

But I have some problems with my hql-statements. Hopefully you guys could give me a hint.

I got a table like:
/*
+-------------------+----------+------+-----+---------+----------------+
| Field            | Type    | Null | Key | Default | Extra          |
+-------------------+----------+------+-----+---------+----------------+
| id                | int(11)  | NO  | PRI | NULL    | auto_increment |
| nUserID          | int(11)  | NO  | MUL |        |                |
| mobilephonenumber | char(50) | NO  |    |        |                |
+-------------------+----------+------+-----+---------+----------------+
*/

This table is mapped to a class like:
package model.hibernate;

public class Product
{
    private Long id;
    private Long nUserID;
    private String mobilephonenumber;

    public Long getId()
    {
        return id;
    }

    private void setId(Long id)
    {
        this.id = id;
    }

    public Long getnUserID()
    {
        return nUserID;
    }

    public void setnUserID(Long nUserID)
    {
        this.nUserID = nUserID;
    }

      public String getMobilephonenumber()
      {
          return  mobilephonenumber;
      }

      public void setMobilephonenumber(String  a)
    {
        mobilephonenumber = a;
      }
}

It is mapped like:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

    <class name="model.hibernate.Product" table="products">
        <id name="id" column="id">
            <generator class="increment"/>
        </id>
            <property name="nUserID"/>
            <property name="mobilephonenumber"/>

    </class>

</hibernate-mapping>

It is also registerd in the hibernate.cfg.xml like:
        <mapping resource="attentionizer/model/hibernate/Product.hbm.xml"/>

I tries to create a query like:
Object[] parameters = {customer.getId()};
Collection products = CollectionService.getCollection("from Product where Product.nUserID = ?", parameters );

The code for the query looks like:
    public static synchronized Collection getCollection(String hsql, Object[] parameters)
      {
        HibernateUtil.getSessionFactory().getCurrentSession().beginTransaction();

        Query query = HibernateUtil.getSessionFactory().getCurrentSession().createQuery(hsql);

        if(parameters != null)
        {
            for(int i = 0; i < parameters.length; i++)
            {
                query.setParameter(i, parameters[i]);
            }
        }

        List result = query.list();

        HibernateUtil.getSessionFactory().getCurrentSession().getTransaction().commit();
        HibernateUtil.getSessionFactory().close();

        return result;
    }

But I just get this error:

500 Internal Server Error
org.hibernate.hql.ast.QuerySyntaxException: Invalid path: 'Product.nUserID' [from model.hibernate.Product where Product.nUserID = ?]
    at org.hibernate.hql.ast.ErrorCounter.throwQueryException(ErrorCounter.java:59)

    at org.hibernate.impl.QueryImpl.list(QueryImpl.java:74)
    at tools.CollectionService.getCollection(CollectionService.java:36)

So if any one could help me out it would be great!
