[jboss-user] [EJB 3.0] - Re: Displaying EJBs within JavaScript: what about the Entity

[SmokingAPipe]

Any ideas on this?  I've looked around the net and seen that I'm obviously not the only one who is encountering this issue.  You grab your EJBs somehow while in a JSF backing bean, and then when JSP tries to display them, it's an error because they are detached and some members are not initialized.

Solution 1: Use a Filter that keeps an EntityManager hanging around for the duration of the request.  Seems like an ugly way to do it, but I guess that would be "PHP-style", where it automatically frees DB connections when the request is finished.

Solution 2: Use Seam.  Looks like a lot of people like that idea.  I'm thinking about doing it, but I need to get this application in demo soon, and I'm not sure if I want to take on yet another layer of complexity here.  On the plus side, Seam looks quite interesting.  Is this the way to do it?

Solution 3: Anything else?

This is a problem that would be universal in any type of JSP + EJB application, so I'm surprised at how hard it is to find answers on this.  Please let me know if you have ideas.
