Hello everyone,

I have a strange error with play java 2.4.
My test app (Hibernate - MySQL) work in dev mode but when I try to deploy or just try the production mode with the command testProd hibernate go wrong.

There is the stack trace :

public class Application extends Controller {
    @Transactional
    public Result index() {
        JPA.em().find(Person.class, 1L);
        return ok(index.render("Your new application is ready."));
    }
}

And my model :

package models;

import javax.persistence.*;

@Entity
@Table(name="Person")
public class Person {
    @Id
    @GeneratedValue
    @Column(name="id")
    private Long id;

    @Column(name="lastname")
    private String lastname;

    @Column(name="firstname")
    private String firstname;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getLastname() {
        return lastname;
    }

    public void setLastname(String lastname) {
        this.lastname = lastname;
    }

    public String getFirstname() {
        return firstname;
    }

    public void setFirstname(String firstname) {
        this.firstname = firstname;
    }
}


Any idea?

Regards

Set

PlayKeys.externalizeResources := false
in your build.sbt
This should fix it.

Check out https://github.com/playframework/playframework/issues/4590 (the last comments are probably the interesting ones).

Best Regards,
