I've never used it either but I know from other peoples experience that it
works great for EJB 2.1.
I don't know how good it supports Ejb 3 though but you can always ask at
http://forum.springframework.org/forumdisplay.php?f=29.
Cheers,
Peter

Subject: Re: [s2] Struts Dependency Injection and EJB3 - support ? or how
can i Do it?
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.
Joe
