javax.persistence.PersistenceException：没有名为EntityManage

我正在尝试按照我老师的文档提供的信息建立一个简单的jpa 2.0项目.我已经在这几个小时了,但不管我做什么,当我尝试创建一个EntityManagerFactory时,我总是得到这个异常：
我发现了很多关于这个例外的类似问题,但没有我能够解决的解决方案.我在这做错了什么？

我从Eclipse创建了这个项目(没有命令提示符)

Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named course
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:56)
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:34)
    at message.SaveMessage.main(SaveMessage.java:8)

package message;

import java.io.Serializable;

import javax.persistence.*;

@Entity
public class Message implements Serializable {

    private long id;
    private String text;

    public Message() {

    }

    public Message(long id,String text) {
        this.setId(id);
        this.setText(text);

    }

    @Id
    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;

}

        EntityManagerFactory emf = Persistence.createEntityManagerFactory("course");
        EntityManager em = emf.createEntityManager();

        tx.begin();

        Message message = new Message(1,"Hello world");
        em.persist(message);
        tx.commit();
        em.close();
        System.out.println("message saved");
