Sun addresses the broader question of Java EE 5 compatibility here.
Optimistically, one may expect Java EE 5 production releases of the above servers by the first anniversary of Java EE 5

Sun Java EE 5 RI (based on Glassfish) and Weblogic 10 Preview are Java EE 5 compliant.

JBoss and Oracle are not fully compliant yet, however supports most features of EJB 3 that you need. Hibernate and TopLink Essentials the JPA providers used by JBoss and Oracle respectively are fully compliant EJB 3 JPA 1.0 compliant

Does anyone know if Weblogic 9.2 plus the MP1 patch supports EJB3? Or do we have to wait for Weblogic 10.x?

I don't think tomcat will ever support EJB of any version.

Tomcat is web container.

Tomcat is just a servlet container, not an EJB container. There are/have been ways to use it with various EJB containers (e.g. JBoss and OpenEJB), but Tomcat itself never supported EJBs.

Currently, WebSphere 6.1 supports limited set of EJB 3.0 functionality via aplhaWorks:

https://www14.software.ibm.com/iwm/web/cc/earlyprograms/websphere/was61ejb3/



The EJB3 Feature Pack alpha release contains a preliminary implementation of the Enterprise JavaBeans 3.0 (EJB3) specification.

EJB 3.0 introduces major simplifications and ease-of-development improvements to the EJB programming model and the persistence model. These changes are designed specifically to reduce the complexity of EJB programming, through adherence to the following principles:


Plain Old Java Object (POJO)-based development for both Business Logic and Persistence

No dependencies on external framework interfaces (for example javax.ejb.)

Allows unit test outside the app server

Highly leverage defaults -- Only need specify an item if you do not want the default

Highly leverage J2SE 1.5 annotations -- Annotations may be used stand-alone or in combination with XML descriptors

Persistent data objects matching the persistence domain model -- Full support for inheritance and polymorphism

The EJB3 Feature Pack alpha does not provide a full implementation of EJB3 yet. However, there is enough implemented to build basic applications that drive business logic and persistence



I anticipate full EJB 3.0 (and Java EE 5.0) in WebSphere 7.0.

regards,
MZ

I wonder if people are using JBoss + EJB in production.

Thanks.

Yes. I know a couple of production systems using JBoss + EJB 2.x. Not sure about JBoss + EJB 3 applications, since its relatively new.

"When OracleAS will be released ?"

OracleAS 10.1.3.1 and later supports most features of EJB 3, has complete support for JPA annotations/injections support in Servlet and Application client containers.

Why did you choose JBoss?
How did EJB 3 go with JBoss?

Using JBoss for prototype. It is cheaper to develop on and the customer has heard of it. If it performs well, we'll deploy it to production. Looks great on the bottom line as compared to WebLogic.

EJB 3 is choppy since it is still in beta.

Is JBoss Application Server the only download I need?

Do I also need to download other components listed on JBoss download page such as Apache Tomcat, EJB 3 etc?

Just the JBoss Application Server download is enough. You can find it here. Download the "jboss-4.0.5.GA.zip" from there and extract it to some folder on your machine.
 
It is sorta covered in the JavaRanch Style Guide.
