Stuart released a couple of Seam 3 modules -- XML and Persistence over the weekend. Check out his blog.
Seam XML allows you to configure your CDI beans via XML - very useful and as it has pretty minimal dependencies (just the CDI API and the interceptors API) usable now. I know Stuart plans to move to an API complete beta very soon. You can check out the module page for more on the roadmap
This alpha of Seam Persistence brings JPA and JTA support to CDI outside of Java EE (Stuart has both working on Tomcat) as well as transactions for managed beans anywhere, conversation scoped persistence contexts, and Hibernate Search integration.
On Seam Persistence roadmap are tests for all containers, integration with Envers, easy manual flush mode control and more -- check out the module page
Nice, I've been fielding a lot of questions about transaction handling and LIE's recently with some of the Java EE 6 demo apps /archetypes I've put out, and aside from talking about the issues of EJB transaction handling and rolling your own, I usually tell people to wait and see what Seam 3 brings. I'll be taking a look at it this week and blog about it a bit.
Cheers,
Andy Gibson
