I think the only useful thing you can impelement with a file system
connector is serialization: keep connections from accessing the same file
at the same time. Transactions without versioning would be very difficult.
I don't really see any place for security.

Here is the code I use when you set a 2.x cmp field:

As much as the spec says you shouldn't do io from EJBs, technically you
still can (though I'm not advocating it ;) ). I tried it once and

Pretty sure:

How about using MBean's for that ? Can they be access as normal Beans ?

You used:

It looks like you would need Message Driven Beans.

why not just send the user an email after the order has been processed?
you could process the order using a message-driven bean that sends an email
when completed, since you won't know if the user is still available after
processing the order.

that JBoss uses these either explicitly or implicitly to determine if the
