ConversationScoped, @EJBs and serialization

[vetler]

Hi,

I've googled around for this, but have not found a definitive answer.

The issue at hand, is that PMD (http://pmd.sourceforge.net/) reports that stateless EJBs injected with @EJB do not implement Serializable, and this must be declared transient. Stateless EJBs are passivation capable, right? So there should be no need to declare them transient, if my assumptions are correct.

Is PMD wrong in this case, and can we just disable PMD warnings for this?

TIA,
Vetle

I don't think(tm) stateless EJBs are serialized (what would be the point?). Stateful EJBs are serializable by nature.

Hmmm, yes of course. So then they should be declared transient, and they are reinjected after deserialization of the conversation scoped bean?

I think(tm) a container is free to implement its own strategy how to cache / pool session beans. This includes stateless session beans, I recall I read that some containers pool stateless session beans (thereby saving the creating time).

They will be passivation capable :-)
