Question

I’m trying to build an implementation agnostic maven module which relies on JPA2. Unfortunately, the only Maven JPA dependency is JPA1 based, and consequently, I cannot use EntityManager.detach() method as that is a JPA2 option only.

Ideally, I’d love to be able to specify my javax.persistence dependency in my Pom, and require the app/container to supply the JPA2 implementation. Unfortunately, I cannot find any such dependency.

Is my only choice at this point to declare hibernate-jpa-2.0-api 1.0.0.FINAL as a provided dependency?

Answer 1

The Hibernate JPA 2 classes (javax.persistence…) are here:

<dependency>
    <groupId>org.hibernate.javax.persistence</groupId>
    <artifactId>hibernate-jpa-2.0-api</artifactId>
    <version>1.0.1.Final</version>
</dependency>
