While I have not used it, the Spring Framework provides strategies for
defining Spring Beans which are EJB factories (or something like that.)
Struts 2 works quite nicely using Spring as the Action Factory, which can
take care of resolving all Action dependencies whether or not they are EJBs.

See
http://cwiki.apache.org/S2PLUGINS/spring-plugin.html
for more on using Spring as your object factory

and this Spring documentation on EJBs:
http://www.springframework.org/docs/reference/ejb.html

Hope that helps.
