[Springframework-developer] EJBs and their Bean Factories

[Luke T. <ne...@fr...>]

Looking at the code for the EJB base classes, unless I'm missing 
something obvious (not unheard of), it seems that by default a separate 
bean factory is created for each bean instance.

Is this the desired behaviour? I would have expected them to share one 
for each JNDI key that is used.

At the moment, I have a single beans xml file which holds the 
configuration for my DAOs, AOP stuff etc. and which is used by a set of 
stateless session beans. Each session bean only uses one DAO but it 
seems that if I follow this approach I will end up with an exponentially 
growing number of objects as I add new EJBs. Even if I split each bean's 
configuration into a separate file it still seems inefficient and 
counterintuitive that I end up with an application context per EJB instance.

Luke.
