Re: Re: EJB injection issues from .WAR classes?

if injection is not performed by the container,

EJB lookup should work via:

Context.lookup(<mappedName>)

when I declare my EJB's with:

@Stateless(mappedName=<mappedName>)


I think that should work in Web-Frameworks  without container-based
injection too ??
