Question

I am new to play framework. tried to follow the tutorial http://www.playframework.org/documentation/1.2.4/guide2

when i added the following user class (as instructed in tutorial)

package models;

import java.util.*;
import javax.persistence.*;

import play.db.jpa.*;

@Entity
public class User extends Model {

    public String email;
    public String password;
    public String fullname;
    public boolean isAdmin;

    public User(String email, String password, String fullname) {
        this.email = email;
        this.password = password;
        this.fullname = fullname;
    }

}

I receive the following error:

A JPA error occurred (Cannot start a JPA manager without a properly configured database): No datasource configured

what am i doing wrong ?

Answer 1

I think you might need to configure the database in the application.conf. As you are running the tutorial, using the H2 in-memory database is sufficient. To do that, just uncomment the following line in the application.conf:

db=mem
