Hi all,
I have a few questions on CORBA services in EJB. Thanks in advance
for any help!
Suppose that your application server has some of the services you need,
but not all. Suppose that there is an implementation of a CORBA service
that I would like to use, for example the Notification service (included in
CORBA 2.2). Problem is, I don't see how I could reach these services
from within an EJB.
What I'd like to do is implement or buy implementations of the CORBA
services I need, deploy them on an ORB either running in my application
server or 'besides' it. Either way I would like to somehow access these
services from an EJB. I don't know if this is possible or even smart, so I
turn to you:
Is this possible?
How would I call my CORBA service from my EJB?
Does this imply any restrictions on my choice of application server?
Would I need a separate ORB?
I would love to hear other solutions to this problem, too.
Another question I have is related to my first one. The way I have
understood it (please correct me if I'm wrong), all Enterprise JavaBeans are
idle between method calls. Couldn't there be situations when you would
like to have a running process on the server? I have seen postings to this
list about some kind of batch job scheduling service. I think that in the end
they came to the conclusion that it was best to put this service in a thread
of its own. Would this be a general solution to the situation when you want
to have a running process on the server? Isn't this a bit of an 'unclean'
solution?
Thanks for any help,
Fredrik Bromee
