Recently Spring Roo 1.0.0 was released. However for those interested in using Roo with EclipseLink (in other words for those with a fervent disdain of Hibernate) please note that this is not yet supported. The related online discussion is on the forum and there is an open JIRA for integrating it which you can vote on and watch. Apparently EclipseLink 2.0.0 has a dependency on JPA2 API which is causing issues. It’s a real shame that EclipseLink isn’t supported yet as it would have been useful on one of our projects going forward but this integration can always be done by hand.
