орг.спящий режим.бумага HQL. АСТ. Исключение QuerySyntaxException

---

Привет,
Я новичок в hibernate и столкнулся с проблемой, которая заключается в том, что org.hibernate.hql.ast.QuerySyntaxException класс, который я использовал, не сопоставлен
вот мои файлы, которыми я пользуюсь :
presistence.хм

<<pre>?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"

	xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
	<persistence-unit name="MainTest">
		<class>com.hibernate.Course</class>
		<properties>
			<property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost/test" />
			<property name="javax.persistence.jdbc.user" value="root" />
			<property name="javax.persistence.jdbc.password" value="password" />
			<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
			<property name="hibernate.ejb.cfgfile" value="hibernate.cfg.xml" />
		</properties>
	</persistence-unit>
</persistence

>l
и мой основной класс:

package com.main;

import java.util.Iterator;
import java.util.List;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;

import com.hibernate.Course;
import com.hibernate.Factory;

public class MainTest {

	public static void main(String[] args) {
		MainTest mainTest = new MainTest();
		mainTest.listDatabase();

	}

	public void listDatabase() {
		SessionFactory session = Factory.getSessionFactory();
		Session session1 = session.getCurrentSession();

		Transaction transaction = session1.beginTransaction();
		Query query = session1.createQuery(" from Course ");
		// List course =
		// Factory.getPrimaryEM().createQuery("from course").getResultList();
		List course = query.list();
		Iterator iterator = course.iterator();
		while (iterator.hasNext()) {
			Course course1 = (Course) iterator.next();
			System.out.println(course1.getCourseId());
			System.out.println(course1.getCourseName());
		}

	}
}

и наконец-то класс конечно :

package com.hibernate;

import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Table;

import org.hibernate.annotations.Entity;

@Entity
@Table(name = "course")
public class Course {
	private int courseId;
	private String courseName;

	@Column(name ="idCourse")
	@GeneratedValue(strategy = GenerationType.AUTO)
	public int getCourseId() {
		return courseId;
	}

	public void setCourseId(int courseId) {
		this.courseId = courseId;
	}

	@Column(name ="CourseName")

	public String getCourseName() {
		return courseName;
	}

	public void setCourseName(String courseName) {
		this.courseName = courseName;
	}

}

Вот исключение, которое у меня есть:

Я использовал Facroty в качестве фабрики для sessionFactory.
