The EJB3 spec indicates that EJB2 and EJB3 can co-exist in a single application.

I wish to migrate my EJB2 stateless session beans to EJB3 stateless session beans.  

This question does not relate to JPA at all (that is a separate piece of work to be carried out in the future)

I'm running on websphere 6.1 with the EJB3 feature pack installed and patched and the profile is augmented (an ejb3 sample app confirms that it works)

What changes do I need to make to my code, web.xml, application.xml, ejb-jar.xml and other websphere specific bindings to convert a SINGLE ejb from 2 to 3?
