Persistence Ebean not working in Play 2.0

To get to know myself with the Play 2.0 platform, I followed the 2.0 2.0 tutorial. Unsubmissive, I cannot get Ebean persistence to work. Mine Task.java

looks like this:

package models;

import java.util.*;

import play.db.*;
import play.data.validation.Constraints.*;

import javax.persistence.*;

@Entity
public class Task {

    @Id 
    public Long id;

    @Required
    public String label;

    public static List<Task> all() {
        return find.all();
    }

    public static void create(Task task) {
        task.save();
    }

    public static void delete(Long id) {
        find.ref(id).delete();
    }

}

But when running the application find

and save

cannot be resolved. I guess I forgot to import the module, but I can't figure out what's on it ...

As Dan W. said, you need to extend the class Model

:

@Entity
public class Task extends Model {
    ....
}

You also need to add the following static method:



public static Finder<Long,Task> find = new Finder(
    Long.class, Task.class
);

Also add the following lines to the file application.conf

to include the database:

db.default.driver=org.h2.Driver
db.default.url="jdbc:h2:mem:play"
ebean.default="models.*"

I believe you need to extend the class Model

.

@Entity
public class Task extends Model {
    ....
}


Hope it helps.
