Hi Jean-Baptiste, Short answer : this is normal.
Explanation : The orginal version of the geronimo-jpa spec jars was copied from the EJB specification (version 3.0 at the time). So JPA 1.0 was named geronimo-jpa_3.0_spec-1.0.jar in Geronimo. With JPA 2.0 the name changed to geronimo-jpa_2.0_spec-xxx. I believe this is the 'more correct' format for the name, but it's really a question for the geronimo folks. Hope this helps, -mike On Tue, Sep 22, 2009 at 8:52 AM, Jean-Baptiste BRIAUD -- Novlog < j-b.bri...@novlog.com> wrote: > Hi, > > the version of Geronimo look older in OpenJPA 2 compared to OpenJPA 1.2.1 > ... > > One can found geronimo-jpa_2.0_spec-1.0-EA8-20090902.182716-4.jar in > OpenJPA 2 > and geronimo-jpa_3.0_spec-1.0.jar in OpenJPA 1.2.1. > > Is it normal ?
