Like most situations, it depends!
The specification is finalized so yes it's ready for prime time. The API makes the development easier (and to me more fun) so yes it's ready for prime time.

Having said that note that
1. Not all application server vendirs implement the specs yet. So, if you are set on a server (e.g. WebSphere) check with your vendor first. As of today, WebSphere Application Server doesn't implement these specs yet
2. EJB 3.0 uses some new concepts that were not available before (e.g. annotations), if you are working under tight deadlines, learning curve could be an issue

In a nut shell, only you can decide whether EJB 3.0 is ready for prime time

Thank you for you reply. JBoss supports EJB3 now. Learning curve should be minimal (and easier!) too.

I would want to emphasis that
Not all Application Server supports JEE

JBoss EJB3 is separate from JBoss Application Server. It is Emebeddable EJB3.0 Container.

Adopting EJB3 will also mean adopting Java 5.0

I would say untill we see more participation, EJB3 is not yet ready for Prime Time.

While at my last job we used EJB3 and Hibernate. It was fantastic. Using JBoss App Server you can a fully compliant EJB3 Container. I highly recommend it myself.

Gayatri,
Try https://glassfish.dev.java.net/ and http://www.netbeans.org/. These websites have some good small and easy to digest EJB 3.0 articles, blogs etc. You could also try EJB 3.0 specifications at http://java.sun.com/products/ejb/docs.html - and they are not that hard to read

Mark,
What makes you think JBoss is fully compliant? Not challenging you... just curious

Well, one of JBoss's employees was on the spec team, JBoss was always following the spec as it progressed and quickly updated it while the spec changed, and are right there with the final spec. If it isn't 100% compliant at this time it is at least over 90%. There isn't a certified compliance yet, but that isn't because JBoss hasn't adhered to the spec yet, it is a matter of Sun getting up to speed.

I will also say that I work for JBoss, so that you know where I am coming from.
