JBoss AS 7.0.1 "Zap" has been released today. It's been one month since AS 7.0.0 was released, so this new release has come in quick time. This new release includes a lot of bug fixes (135 issues in total) that have been mainly reported in the community. Apart from the bug fixes the major features/additions to 7.0.1 are as follows:

* Better JPA integration and plug-ability


As many of you might already know, AS 7.0.0 came bundled with Hibernate 4 version. Users could still package Hibernate 3 within their application and use it. But many users reported issues with Hibernate 3 bundled within their application. Moreover, 7.0.0 did not have a way to allow other JPA implementations (like EclipseLink) to be integrated. As such, major changes were implemented in 7.0.1 to introduce better JPA plug-ability. The JPA reference guide for AS7 is good place to look at the details.

* MDB support


AS 7.0.0 had 2 distributions. One, a purely "web-profile" certified distribution which included EJB3.1 "Lite" support (as mandated by webprofile spec). The other distribution (named "everything") had some more features in addition to "web-profile". EJB3.1 "Lite" doesn't include MDB support. So in AS 7.0.0 we didn't have MDB support. Many users in the forums asked for MDB support to be included in the near future. We decided that it would be good to include it in 7.0.1 and as such, we now support MDBs in the "everything" distribution of 7.0.1. We have had some very good community feedback, on the MDB support, while the development was in progress. So thanks to that feedback, we were able to fix some issues with MDB integration, right in time for the 7.0.1.

So try out the MDB support available in the "everything" distribution of AS 7.0.1 and let us know how it goes.

* EJB3 pool configurations


AS 7.0.0 had hardcoded pool configurations for Stateless session beans. There wasn't a way to configure the pool for the beans. In AS 7.0.1 we have introduced a way to configure pools for Stateless session beans and MDBs. We also allow disabling pools for both Stateless session beans and MDBs. Disabling pools benefits in some cases where the bean construction isn't heavy (like not much in @PostConstruct etc...). I'll blog more about the EJB3 pool configurations in a separate post.

* Ability to bundle application specific JSF version


Users can now bundle their own version of JSF in their applications.

7.0.1 (and AS7 in general) has had a huge community feeback and contribution. A lot of the issues that have been fixed, have been raised by our community members. A big thanks to them for helping us all along, towards AS7 efforts!

As always, give the new release a try and let us know how it goes. We are always looking for inputs to make AS7 better. Report any issues or ask for help in our user forum

I plan to write some more posts around 7.0.1 in the coming days. Also, keep a watch on other blogs from JBoss AS developers and community members around AS7.
