Question

I have two classes: User and Video:

@Entity    
class User{
    @Id
    int id;        
    String name;
}

@Entity
    class Video{
    @Id
    int id;        
    String url;
    User user;
}

When i use this I get the following error:

Could not determine type for: User, at table: Video

I’m using Hibernate through Tapestry. Any suggestions?

Answer 1

Very simple: You need a @ManyToOne annotation on the user field:

@Entity
class Video {
    @Id
    int id;

    String url;

    @ManyToOne
    User user;
}

See the Javadoc for more information.
