Extended Persistent Context
Hello everyone, I would like to know if you think about create an option
that exists in seam 2, that I can open the entitymanager for many requests?

hi rafael,
i guess you are deploying your application in an ee-server.
in such a case you have to be aware of [1] (see the usage with
@PersistenceUnit EntityManagerFactory).
the rest (= wrapping the EntityManager) is the same.

Do you know if the functionality of the link above only works with the
Conversation scope?

hi rafael,
please provide a demo-application which illustrates the issue.
back then it worked and since your own disposer calls #close, it should
still work.

I looked this link when I started my project, but this solution doesn't
work. This solution just create a entity manager with the conversational
scope and the entity manager stay serialized, but with this solution, the
entity manager doesn't stay open during the conversation.
About the best practice of the extended persistence context, here we have a
project in production with seam 2, JSF 1.2, EJB 3 and JPA 1, running in a
JBoss Application Server and this system is used by many people in the
state of Ceará, Brazil. We have around 300 - 400 users concurrent and the
Application Servers are in Cluster.
Can you explain better, this:
"the Deltaspike /CDI style is very nice to work"

I am also curious about best practice for this (right now) and perhaps in
the future. The thing is the Deltaspike /CDI style is very nice to work
with and it would be a preferred API for me.
