how do you implement OpenEntityManagerInView for JEE applications?

[Vladimir Kovalyuk <ko...@gmail.com>]

I came to Wicket from JSF where I used Seam for managing persistence
contexts.
Actually the latest stable version of Seam is incompatible with Wicket 1.4,
and I realized that the project uses just three things from Seam. One of the
critical things is Seam-managed persistence context. When you don't use Seam
long-running conversations it just degrades to something like Open Session
in View.

What solution do you use for JEE applications? AFAIK there are several
projects that use JPA in contextless form. But it does not work so simply
with JNDI and JTA in JEE container.

two solutions come to mind:

1. openEMinViewFilter (see Spring source for such an implementation)
2. custom requestcycle that does this for you (search the list, the
wiki, or see Wicket in Action chapter 13)
