My Model is NOT an Entity Bean registered with this server?

Question

I'm using Playframework for the firstime in combination with Ebean.

Now I want to use MySQL as database so I added:

db.default.driver=com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://localhost:3306/TestDb"
db.default.user=root
db.default.password="test"

to my Application.conf file.

I disabled the evolutionplugin in the Application.conf file because I don't want to use it.

evolutionplugin=disabled

I added the ebean default location for my models:

ebean.default="models.*"

In my package models I've got a class User like this:

import play.db.ebean.Model;

import javax.persistence.Id;

public class User extends Model {
    @Id
    private Integer id;
    private String firstname;
    private String lastname;
    private String email;
    private String token_facebook;
    private String token_google;
    private String reg_date;
    private String id_facebook;
    private String id_google;

    public static Finder<Integer, User> find = new Finder<Integer, User>(
            Integer.class, User.class
    );
}

Now I just want to retrieve every user like this:

User.find.all()

This gives me:

[error] play - Cannot invoke the action, eventually got an error: javax.persistence.PersistenceException: models.User is NOT an Entity Bean registered with this server?
[error] application -

My database has every field that my User class has.

Anyone an idea?

Answer 1

I found the problem.

I forgot to annotate the class with the @Entity annotation.

This solved the problem.
