与ManyToOne关系的未知实体错误

Question

OK, so I've designed a basic CRUD an an exercise. It has 2 tables Jobs and Employees. I'm trying to create a many to one relationship, but when I click the link to go to the Employee Entry page it throws an error that kicks off with the @ManyToOne referencing an Unknown Entity.

Here is what I've got in my Employees.java

String jobName;

@ManyToOne(fetch=FetchType.EAGER)
@Fetch(value = FetchMode.JOIN)
@JoinColumn(name = "Job_Name")
@Column (name='jobName')
public String getJobName() {
return jobName;
}

public void setJobName(String jobName) {
this.jobName = jobName;
}

Any idea what i"m doing wrong and how to resolve this?

As per your comment,i think you can define relationship between these two entities like below.

@Entity
@Table(name="employee")
class Employee{

  @Id
  @GeneratedValue
  private Integer id;

  @ManyToOne
  @JoinColumn(name = "job_name")
  private Job job;

 // other column and getter and setter
}

@Entity
@Table(name="job")
class Job{

      @Id
      @GeneratedValue
      private Integer id;

      @Column(name="job_name")
      private String jobName;

      //provide other column and getter setter

}
