Hello Tim,
before I get your answer I decided to make a complete mess in our
network, so I rewired computers in a way that right now "ubu" is the
first computer connected directly to the Internet. I have inserted a
second network card, configured it with public IP address and
re-configured configured Glassfish. This is fresh V2 build 33 now.
Ubu's iptables configuration includes entry that opens ports: 4848
(for remote administration) 8080 and 3700
In Glassfish webadmin:
1) HTTP Service -> HTTP Listeners -> http-listener 1: Server Name:
my.dnsname.com:8080
2) ORB->IIOP Listeners->orb-listener-1: Network Address: xx.xx.xx.xx
(its my public IP), port 3700
(are the two steps above a proper way to configure Glassfish? Or maybe
I should let them be default and manage this on some higher level?)
I have configured JDBC as well and deployed application's .ear file.
Everything works fine, I cannot tell if it would work if Ubu would be
still as it was before. It must stay like this for few days or even
more, as I cannot close Glassfish until our customer see and try
application...
Thanks for your help,
Witek
p.s.
I opened traffic monitor to see how much data is needed to be
transfered, when I open, for example, the "customer details" form in
our application. I was shocked when I saw that that simple operation
generates 36kB that is transferred from AS into ACC and about 25kB
from ACC into AS. The service looks +/- like this:
//stateless session bean:
Customer c = em.find(Customer.class, id);
return c;
This is more or less the main point of client-server interaction when
opening such a form, maybe few more little queries on very small
entities... The Customer entity bean does not annotate anything as
EAGER or LAZY, so defaults are taken and most of columns are nulls
right now. Do you know if I could try to use some "profiler" to see
exactly which session beans calls generates how much traffic?
