I have no problems with the callback server not being able to receive callbacks
from other servers.
I have been trying to work out how to configure the multiplex transport for
jboss messaging and I have to admit I'm still a bit confused since there seem
to be so many different ways it can be configured.
For the JMS scenario, we want the following:
Each JMS connection to map to one multiplex connection using it's own unique
physical tcp connection.
Each JMS connection to be able to receive callbacks along the same tcp
connection.
So far, I believe that can be configured in the following way:
1) Firstly on the jms server I start a connector:
Connector connector = new Connector();
InvokerLocator locator = new InvokerLocator("multiplex://jms-server:9090");
connector.setInvokerLocator(locator.getLocatorURI());
connector.create();
handler = new JBossMessagingInvocationHandler();
connector.addInvocationHandler("JMS", handler);
connector.start();
2) On the jms client, when a new JMS connection is created I need to do two
things:
a) Create a client that will be used for the jms client --> jms server
synchronous invocations:
String locatorURI =
"multiplex://jms-server:9090/?clientMultiplexId=connection1";
InvokerLocator locator = new InvokerLocator(locatorURI);
Client client = new Client(locator);
This will cause a multiplex connection to be created on a physical tcp
connection from jms-client to jms-server.
I have added the parameter clientMultiplexId to identify this connection so
that it can specified when creating the callback server so it knows to use the
same multiplex connection for the callback server.
b) Create a callback server utilising the same multiplex connection created in
a):
connector = new Connector();
String locatorURI = "multiplex://jms-client:xyz/?serverMultiplexId=connection1";
InvokerLocator locator = new InvokerLocator(locatorURI);
connector.setInvokerLocator(locator.getLocatorURI());
connector.create();
connector.start();
This will create a virtualserverinvoker on the client, utilising the same
multiplex connection.
(Question: What port do I specify in xyz? Does this represent a real port? If I
don't care can this be auto-allocated?)
Does that sound about right? Or I am I missing something here?
