Hi Thank you for reading my post Is there any news about when will IBM release its websphere application server certified for Java EE 5 development and deployment?
IBM has released an "EJB3 Feature Pack" for WAS Version 6.1 that will allow you to deploy EJBs that follow the EJB3 specification to WAS. See this link for details.
It's really more something for developers to play with, though, than something you'd want to put into production.
