One of the cooler hidden features in jOOQ is the JPADatabase, which allows for reverse engineering a pre-existing set of JPA-annotated entities to generate jOOQ code. For instance, you could write these entities here: @Entity public class Actor { @Id @GeneratedValue(strategy = IDENTITY) public Integer actorId; @Column public String firstName; @Column public String lastName; @ManyToMany(fetch … Continue reading jOOQ 3.10 Supports JPA AttributeConverter

A Beginner’s Guide to Using Java EE with jOOQ

A DBA’s point of view of Hibernate
A very nice little rant on Hibernate: http://jeffkemponoracle.com/2011/11/25/3-reasons-to-hate-hibernate While I don't agree 100% (e.g. CRUD/OLTP really is different from OLAP, and Hibernate is a strong CRUD tool), I certainly share most of his feelings.

With the upcoming release 1.6.4 and the implementation of #198, jOOQ will start to better integrate in "standard" J2EE architecture. While jOOQ is being developed as an alternative to JPA, it should not compete with it. This means that there are some parts in JPA which can easily co-exist with jOOQ in a J2EE application: … Continue reading jOOQ makes a step forward towards JPA
