I’m trying to get EclipseLink to work with Spring (MVC and spring-data) version 3.1.1 and I’m running to a problem right from the outset. The error below occurs on starting up Tomcat (v7.0). I’ve searched for the error but come up with very little and I’m not sure where to go next. There is some talk of this problem occurring when using interfaces with Entity classes but as you can see my User.java class extends nothing.

@Entity
@Table(name = "user")

@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
private Long id;
@Column(name = "first_name")

You are importing the wrong
@Idannotation. remove the spring one, add the javax.persistence one.Replace
