Summary: binding problem with more networkinterfaces

Initial Comment:

I encoutered the following problem when migrating my 
client application to citrix (ICA) client. 

The new envirionment is as following:
The citrix clients communicite with each other by means 
of a seperate networkinterface in de range of 
xxx.xxx.34.??. While the second networkinterface ( 
xxx.xxx.33.??) is used for connectivity with backbone to 
all the network servers (for mail/sql/OPENJMS/etc.).

The problem 
When my jms app. is started on one of the citrix clients 
the connection is initialized in about 15 seconds without 
any errors). When sending a message to a Topic, the 
message actually arrives at the OPENJMS server, but 
the citrix client(s) dont't receive the message, while they 
are also listening to this Topic!

We found out that when we connected our OPENJMS 
server to the ICA network (xxx.xxx.34.??) the problem 
disappeared. Then we disabled the xxx.xxx.34.?? 
interface on that server and the clients didn't receive any 
messages again.


From the above I concluded that for some reason the 
ICA client bindings where send to the OPENJMS server, 
while I expected of course the backbone bindings.

Is there something I can do to solve this problem, or is 
this a bug? Any suggestion is welcome. Thx.


Below are the specific code snippets I used in the client 
app:

- for the connection:
        properties.put
(Context.INITIAL_CONTEXT_FACTORY, "org.exolab.jms.
jndi.rmi.RmiJndiInitialContextFactory");
        properties.put
(Context.PROVIDER_URL, "rmi://10.50.34.29:1099/");
	...
        TopicConnectionFactory factory = 
(TopicConnectionFactory) context.lookup
("JmsTopicConnectionFactory"); 

- I used a seperate sessions for sending and receiving 
(spawn from the same connection).

	//for sending
	topicsession = 
connection.createTopicSession(false, 
Session.AUTO_ACKNOWLEDGE);		
	...
	publisher.publish(topic, jms_message, 
DeliveryMode.NON_PERSISTENT, 4, 0);  


	//for receiving
	topicsession_2 = 
connection.createTopicSession(false, 
Session.AUTO_ACKNOWLEDGE);	
	...
	topic = (Topic)context.lookup(topic_name);
	

- OPENJMS version: openjms-0.7.6.1

Yep, using the tcp connector did the job perfectly! The only 
difference is that it takes a view seconds 'to connect' to the 
topic for the very first time.

Thank's a lot!

You may need to use the tcp connector in order for this to work 
properly. It provides support for NAT firewalls/multihomed hosts.
See the configuration reference 
($OPENJMS_HOME/docs/config/reference.html#TcpConfiguratio
n) for more details.

Also note that you should be 
using "org.exolab.jms.jndi.InitialContextFactory" instead 
of "org.exolab.jms.jndi.rmi.RmiJndiInitialContextFactory" - the 
latter doesn't exist beyond version 0.7.6.x.
