Re: [weld-dev] persistence and transactions outside Java EE

I don't see why would want to introduce a new kind of thing. Just let managed beans have declarative txns.

I came up with an idea that may be worth considering. Perhaps the Java EE platform can recognize another class of bean that has persistence and transaction capabilities, but not the rest of EJB. Here's my proposed breakdown, in terms of airplane seat classes (I was on an airplane at the time). First class - EJB session bean Business class - local transactional bean Coach - Simple managed bean The main differientiator of a "business class bean" from an EJB is that it would have the option to use local transactions, just like an application-managed JPA persistence unit. It would also not support any HA concerns. But it would be a drop in replacement for so-called "lightweight" transaction beans that Spring offers. Then, we wouldn't need to do anything special in Weld / Seam 3. All we would need is to be able to support these types of beans in a servlet container, the same way that Weld supports those environments. But it would be a standard part of Java EE (6 MR1 or 7). If we feel like we need to support this use case in Seam, then clearly there is still something missing in Java EE. -Dan On Wed, Nov 18, 2009 at 6:10 PM, Gavin King < <gavin.king(a)gmail.com&gt; gavin.king(a)gmail.com&gt; wrote: > I think we should try and follow the Java EE models as closely as > possible for this stuff.
