EJB 3.0 specification now becomes proposed final draft. You can access the specifications from JCP Website.
The EJB 3.0 greatly simplifies programming model for EJBs. All types of EJBs are now POJOs and XML descriptors are out of develpoper's way (these are optional)
Here is a link to an article on EJB3 that I wrote about a year back that summarizes how EJB3 is simplifying developer's life. Please note that some code examples are dated since the changes in the API in the latest spec.
EJB 3.0 Java Persistence API standardizes the O-R mapping and entities are now POJOs similar to TopLink and Hibernate. Reference implementation for EJB 3.0 Persistence is derived from Oracle TopLink and open sourced in the Sun's Glassfish project. So you can get started with EJB 3.0!
You can look for EJB3 Samples and articles at the Oracle’s EJB3 Resource Center.
Oracle and JBoss have EJB3 preview implementations for long time and now Sun has EJB3 implementation in the GlassFish. We will now see vendors coming up with implementation that comply with EJB 3.0 proposed final draft. You can review the spec, play with preview implementations and send your feedback to EJB 3.0 expert group at ejb3-pfd-feedback@sun.com.
