How to generate object @Entities from database?

Question

I want to generate JPA's @Entitys from database (but I want it to be object oriented). for Example

@Entity
@Table(name = "badges")
public class Badges implements java.io.Serializable {

    private Integer id;
    private User user;
    private String name;
    private String date;

It would be cool if it also support ManyToOne, OneToMany, Parent and ManyToMany.

P.S. I tried JBoss Tools(Hibernate Tools) and I did not work for me.

Use JBoss Tools (formerly hibernate tools).

Quote from their site:

Reverse Engineering: The most powerful feature of Hibernate Tools is a database reverse engineering tool that can generate domain model classes and Hibernate mapping files, annotated EJB3 entity beans, HTML documentation or even an entire JBoss Seam application in seconds!

I tried, but I was not able to configure it :( and when I did it It just did not generate the files.

Make sure you have the latest version of the jboss tools and follow this tutorial: docs.jboss.org/tools/3.1.0.GA/en/hibernatetools/html/…

I have 3.2.0, maybe It just doesnt support MySQL. However I dont see any pictures there that shows it generates object oriented @entities(I get it to generate @entities with fields like Integer userId).

@01: a) MySQL is supported if you supply the mysql driver jar b) see the exporter section docs.jboss.org/tools/3.1.0.GA/en/hibernatetools/html/… : 'Generate EJB3 annotations' is what you want.
