Hi Werner,
re: "For example with netstat I can see, that *2437* is a used port. I am wondering
that I could recognize that this port is used by my testprogram istself"
It really wouldn't do any good. When you make a call on an EJB, it filters down to
Remoting, which, if it can't find a pooled connection to reuse, will create a new
socket, leading to ServerSocket.accept() returning a socket on the server.
It seems like something is preventing the client from completing the initialization of the
connection, but I can't imagine what it is. You could use Wireshark to monitor what
bytes, if any, get sent from the client to the server.

Hallo,
now we have tried to attach jboss to another network interface. We enabled a second
network card with another ip. Then I started the jboss with -b <another IP>.
I wondered, that this do not help. I thought, Ports are unique to a network-card-ip.
Now I have installed the JBoss on another server where he can work alone. This works fine.
But I'm looking for another solution.
Is there any possibility, to reduce the number of request-ports?
At the moment I am experimenting with pooled Invoker.
In conf/standardjboss.xml I have changed the sections for stateless and statefull ejb:

With this configuration change I hoped, that I get a pooled connection for ejb 3.0.
But it seems, that there is something wrong because I still get information, that each
request starts a new WorkerThread with a different port:
2012-03-23 09:26:11,359 INFO [STDOUT] (WorkerThread#1[192.168.1.24:2025]) sayHallo: + 90
2012-03-23 09:26:11,374 INFO [STDOUT] (WorkerThread#0[192.168.1.24:2026]) sayHallo: + 91
2012-03-23 09:26:11,374 INFO [STDOUT] (WorkerThread#1[192.168.1.24:2027]) sayHallo: + 92
2012-03-23 09:26:11,374 INFO [STDOUT] (WorkerThread#0[192.168.1.24:2028]) sayHallo: + 93
Next notice was, that ~ port 4500 the client port is created from ~ 1000 to 4500 and so
on.
But after ~ 4000 fast calls to my test method I get a new exception:
org.jboss.remoting.CannotConnectException: Can not get connection to server. Problem

After this exception I can call my ejb.method again until the next exception.
This exception I also will get, if I use the unchanged standardjboss.xml configuration.
My question:
Is something wrong with my pooled Invoker configuration?
Is this CannotConnectException normal, that I have to expect, or is this only occuring
with my special test?
Where can I configure the parameter for the pooled Invoker? For example port and
pool-size?
Thank you,
Werner

Hallo,
is it possible to configure JBoss, that he uses not so much worker-threads?
Or that the worker-thread uses ports only in a short range?
Thank you,
Werner

Hi Werner,
Sorry for the delay. Have you made any progress?
1) The pooled invoker isn't part of Remoting, and I'm not very familiar with it.
I don't believe it is used by default in any Application Server subsystem.
2) There is no way in Java to control the ports assigned by ServerSockets. However, the
range can be set at the operating system level. For example, see
http://http://www.ncftp.com/ncftpd/doc/misc/ephemeral_ports.html

Hallo Ron,
very interesting this ephemeral ports document.
It could be a good help, because I have recognized, that on Windows 2008 server I have
none problems with blocking.
In Windows 2003 server there is only a range of ca. 3000 ports for uses with client socket
ports.
We want try to change this range.
Thank you for help,
Werner
